Override queryset for admin Inline

[Nick]

I have an admin set up with three inlines.  I would like to filter the
inline's editable options by a variable that is defined in a settings
file.  I can over ride the actual admin pieces for each of the inlines
(they all have full admin screens of their own). But I can't seem to
get the standard def queryset(self, request): etc. over ride to work
for inlines. I have seen a little talk about how inlines require you
to create a new manager to filter the list of options.

Here is my inline admin code:

class CandidateInline(admin.TabularInline):
 model = Candidate

fields = ['%s_vote' % (race_type)]

extra = 0

 ordering = ('party', 'last_name')

## here is where the trouble is starting, I'd like to get rid of
everything that isn't status 1 ###

 def queryset(self, request):
 qs = super(CandidateInline, self).queryset(request)
return qs.filter(status="1").exclude(party="Independent")


and here is the primary admin model that this inline is attached to:

class RaceAdmin(admin.ModelAdmin):


 inlines = [
CandidateInline,
PrecinctInline,
]


form = RaceForm

 fieldsets = (
 ('General Race Information', {

'fields': ('name', 'office_name', 'type', 'county',
'general_winner')
 }),
   ('Partisan Race Outcomes (Runoff)', {
'classes': ('collapse',),
   'fields': ('runoff_winner_d', 'runoff_winner_r',
'primary_advance_d', 'primary_advance_r'),
}),
('Non Partisan Race Outcomes (Runoff)', {
'classes': ('collapse',),
'fields': ('runoff_winner_np',)
}),
 )
   list_display = ('name', 'type', 'county', )
list_filter = ('type', 'office_name', 'county')
ordering = ['name']


 # redefine the queryset to get rid of finals
def queryset(self, request):
qs = super(RaceAdmin, self).queryset(request)
return qs.filter(type="2")

Ah... I didn't think of views.  Haven't used them in a while, but that's
worth a shot, I think, since that way, I might not have to touch the Django
code at all.

Splitting LONGTEXT column to its own table?

[Nick Arnett]

I'm thinking that I could get a pretty good performance improvement on a
couple of tables by moving their LONGTEXT columns into their own tables.
Just wondering if there's anybody here who has done something like that - is
there a way to do this transparently to Django, so I don't have to re-write
every piece of code that uses those tables.

In other words, I'm looking at vertical partitioning, but only across
tables, not databases, as transparently as possible to the code that I've
already written.

Thanks in advance for any pointers.

updating admin values with other fields

[Nick]

I have a save override in my admin file that catches a value from one
field and applies it to another. The values it grabs from a manytomany
field.

I can get it to work, but only when I save twice. It looks like it
needs the manytomany to update with the new values and then it needs
to second save to assigne the values to the other field.

Here is the method override:

 def save_model(self, request, obj, form, change):
obj.primary_winner_r = obj.primary_advance_r.values_list('id',
flat=True)
obj.primary_winner_d = obj.primary_advance_d.values_list('id',
flat=True)
obj.primary_winner_np =
obj.primary_advance_np.values_list('id', flat=True)
obj.save()

Re: save a values_list to a charfield

[Nick]

It is a bit of a last minute deal and will be changed after today, but
we had a handful of "improvements" handed down to us from management
and this was the fastest thing we could come up with using some old
mysql query logic and several already built templates for output.

I appreciate the help.

I am getting this to save but I can't get it to output properly

it's outputting as [16L, 451L, 521L] for a list of id's, which it

save a values_list to a charfield

[Nick]

I am needing to do some duct taping for a project that is going on
right now. In it I need to take a values_list of id's from a
ManyToMany field and save those values to a varchar field so a mysql
query can access the values. I am working with two different sets of
developers and this is the best we can come up with in such a short
period of time


Here is the model:

Candidate
filing_id = models.IntegerField()
name = models.CharField()

Race:
name = models.CharField()
primary_advance = models.ManyToManyField('Candidate')
primary_advnace_list = models.CahrField()

def(save, *args, **kwargs):
primary_ids = self.primary_advace.values_list('id', flat=True)
if primary_ids.count() > 0:
primary_advance_list = primary_ids
else:
primary_advance_list = []
super(Race, self).save(*args, **kwargs)

I've tried this but I'm coming back with empty values for the list
fields.

modelformset vs. inlineformset vs. DIY

[Nick]

I have inherited a project with a tight deadline and I am lost for how
to proceed.

There are two tables: Canididates and Race.

The race table holds 145 different races with information about
precincts, winners of different stages of the race (primary, runoff,
gneral)

The Candidates table has 1100+ candidates, each one is assigned to a
specific race via a FK and a list of three race vote totals (general,
runoff, primary)

I am supposed to create a way to display each race based on a search
and then return the candidates associated with that race so that the
race vote totals can be updated. I will also need to be able to update
values in the Race table.

It would be highly preferable for this to be seemless for the data
input people. I am looking at producing something like this:

Race 1
precincts reporting input - precincts total (static value)
Candidate 1 primary vote input - Candidate 1 status (active,
eliminated)
Candidate 2 primary vote input - Candidate 2 status (active,
eliminated)

winner of primary (list of candidates)

I have most of the form fields and widgets ready to go, but being able
to edit multiple entries in two different tables seemless has me
stuck.  Is this something that I should handle in inlineformsets since
I am spanning an FK? Would I need modelformsets to display all of the
candidates?

I can easily truncate the Race table and change it so that it has a
many to many relationship to all of the candidates instead of the
Candidates having an FK relationship to the race? Would that give me
more flexibility?

Thanks for the help in figuring this out, this has been an incredibly
stressful project.

Re: values() returning more than values

[Nick]

It looks like its returning every organization instance in the table,

There are about 190 organizations and 900 totals entries, each of
which are assigned an organization.

The count on the query is correct, but when I output the actual values
it returns every entry in the table, so I'm seeing multiple duplicate
organizations.

values() returning more than values

[Nick]

I may be misunderstanding the values method but it is returning
duplicate results when I use the distinct method. I have a query that
pulls the values of a column:

Readers = Readers.objects.values_list('organization').distinct()

The count returns 189 results but when I send it to output to a csv it
returns all of the values, with duplicates which is something like 900
entries.

Any help is appreciated.

formatting values list

[Nick]

I would like to format the output of a values_list into something a
little more usable for a CSV.

My view is really simple

def values_view(request)
list = MyModel.objects.values_list('id', 'name', 'type')
template = loader.get_template('mytemp.html')
c = Context({'list': list})
html = t.render(c)
HttpResponse(html)

my template looks like this

{% for item in list %}
{{item}}
{% endfor %}

it spits out a list of things like this:

(u'id', u'name', u'type), (u'id2', u'name2', u'type2)

etc. etc.

How can I format a values_list so I could return something like a
table or csv?

so:

id, name, type
id2, name, type

etc. etc.

Thanks for the help
Nick

The only honest answer is "it depends."  But the good news about Webfaction,

cheapest option and then upgrade at any time.  And downgrade.  They make it
easy.

You'll get warnings from them immediately if you exceed the allocated
memory.

I was able to run a database-intensive app under Shared 1 for a long time.
It was only when I started doing some heavier analysis that I had to bump up
to Shared 2.

Hi,

The offending config entry in my case was:

Firefox 3.6.6

I can reproduce the problem anytime by visiting about:config and
changing "intl.accept_languages" to

*.djangoproject.com will stop responding, (all?) other websites seem fine.

Yep, that's the one!
I tried to open chrome://global/locale/intl.properties as a link in 
Firefox, and (oh, the surprise :P ) it's a settings file.
Either the file doesn't get resolved unto something useful in my 
platform (I'm using ubuntu-based) or it's something depreciated and it's 
a migration issue.
Also checked the Firefox bugzilla and there are indeed a couple of bug 
reports for it.


My feelings still stand. Other than making sure that django itself 
handles such erroneous values gracefully,  the list shouldn't be too 
concerned about it.


Now, I wonder if there's a way we can give a heads-up to the 
djangoproject.com and djangobook.com maintainers a heads-up on this is 
issue, so they can cater for it.

Hi Russ.
I hate to admit that I didn't saved that offending value so someone can 
reproduce this.


My reasoning back then for not raising a bug on django was this:
1. It was an obvious invalid value. As I said, Weave probably introduced 
it at some point (I guess while still in beta) but other than that, it 
could also be a number of things. Fixing that locale value solves it for 
good. So I rinsed, wiped, forgot.
2. I tried to access some other django-powered sites with l10n, and they 
loaded just fine. Only djangoproject.com and djangobook.com had the 
problem. So my guess was that it was caused by something else on that 
sites' stack and not django itself.

3. Improving the error-handling of django just didn't cross my mind.

I hope someone else with the same problem here could provide you with 
the offending value.

Re: Trouble writing a view for a model

[Nick]

I think a choice field is probably best, then you can customize the
presentation in a forms file.

class Question(models.Model):
q_cjoices = (
('choice1', 'choice1'),
('choice2', 'choice2'),
('choice3', 'choice3'),
('choice4', 'choice4'),
('choice5', 'choice5'),
)

title = modelsForeignKey(Title)
choices = models.CharField(choices=q_choices, max_length=100)

In the form declaration you can use this

from models.Questions import q_choices
from django.forms.extras.widgets import RadioSelect

choices = forms.CharField(choices=q_choices, widget=RadioSelect)

That would work unless you want someone to be able add choices based
on individual questions in which case you'll need to use a many to
many field, something like this:

Question(models.Model)
title = models.ForeignKey(Title)
Choice = models.ManyToManyField(Choice)

class Choice(models.CharField)
choice_1 = models.CharField( etc. etc. etc.

__init__ custom form validation

[Nick]

I am working on a validation that will require a field be filled in if
it is another field enters on of three values:

For example:

I have a form

class myform(forms.Modelform):
field1 = forms.CharField
field2 = forms.Charfield
field3_type = forms.CharField(choices=choices)
field3 = forms.DateTimeField(required=True)

def __init__(self, field3_type, *args, **kwargs):
super(myform, self_.__init__(*args, **kwargs)
if field3_type in ('option 1', 'option 2', 'option 3'):
self.field['field3'] = forms.DateTiemField(required=False)

The view:
if request.method == 'POST':
form = myform(request.POST)
field3_type = form.cleaned_data['field3_type']
if form.is_valid():
# some form processing
else:
   form = myform()

When i try to use the form I get an error at the myform() line stating
that __init__ takes exactyl 2 arguments and only 1 is given.

Any thoughts?

Re: www.djangoproject.com

I too have upgraded my Ubuntu systems over several versions in the

weeks, which leaves me wondering how the nonstandard setting got into 
the profile in the first place.



Yea, for some reason, my thoughts went to Weave too. Maybe it has 
something to do with it, maybe it doesn't. Haven't got any more trouble 
since I fixed it though.

Glad I could help :)

Re: www.djangoproject.com

[Nick Raptis]

Sorry for the rant but I can finally express my delayed frustration on 
this bug..


I first I spent some 2-3 hours trying to find out if this problem came 
from a broken ipv6 configuration.
Then, I actually had to delete all my profile files (delete half, find 
out if it solves it, restore, delete half again) until I knew that 
prefs.js (the about:config file) was responsible.
I then checked the more than a 6000 lines of that file in the same 
manner (deleting half the lines each time) to find the offending option.

At that time I thought half my hair had gone grey!

The only two sites affected by this was djangoproject.com and 
djangobook.com Could be a django configuration issue on those, as other 
django powered sites behaved normally.


I'm SO glad that my frustrating time hunting this down actually helped 
another soul! :D


I don't know why my profile had the locale option as such. I've migrated 
this profile from windows, then ubuntu karmic to ubuntu lucid, and I'm 
also using weave sync so I can't tell for sure. Hopefully, once you know 
it's there you can easily fix it :)


I'm also sorry for double-posting the last mail. I have both mail 
accounts configured for the  list and thought only one would go through 
as the first answer I sent lagged significantly. I hope this gets sent 
properly.


Glad i could be of help, Nick

That's it.  You have to *remove* this non-standard value, it's not
sufficient to add another locale to the first position.

Re: Query raises a DoesNotExist error

[Nick]

A lot of this is me trying to find out why it's failing. The problem
I'm getting is that there is a FullProfile associated with the email
address. When i go through the steps in the shell it works perfectly.
When I run it through the form it throws an error. If you look at the
custom ValidationError I am checking to see if I can get an error to
spit out any information for that profile that is being submitted in
the form.

Each time I get the error to return the test information without fail.
If I do try to submit an address that isn't in the FullProfile table
then I get a different DoesNotExist error, it jumps right over the
custom validation error.

So the custom ValidationError triggers when there is a profile in the
DB and the default debug page DoesNotExist triggers when there isn't a
FulLProfile associated with the email address.

Query raises a DoesNotExist error

[Nick]

I am working on a form to resend an account activation email for newly
registered users who did not receive their first email.

The form is currently raising a DoesNotExist error and I can't figure
out why:

Here is the activation code:

class resend_activation(forms.Form):
email = forms.EmailField(label="E-Email")

def clean_email(self):
email = self.cleaned_data["email"]

try:
FullProfile.objects.get(email=email)
except FullProfile.DoesNotExist:

 test =
FullProfile.objects.get(email=self.cleaned_data['email'])
 raise forms.ValidationError("%s" % (test))

def send(self):
email = self.cleaned_data['email']
user = FullProfile.objects.get(email=email)
thread = Thread(target=send_activation, args=[user])
thread.setDaemon(True)
thread.start()

Here is the view:

def resend(request):
if request.method == 'POST':
form = resend_activation(request.POST)
if form.is_valid():
resend = form.send()


return HttpResponseRedirect("../activate_message")
else:
form = resend_activation()

return render_to_response("registration/resend.html", {'form':
form })

Everytime I try to use the form I get a "FullProfile matching query
does not exist." error. But in the above code I added a little test to
see if the query was returning any values and it is. I have no clue
why this portion of process is holding up everything else.

URL configuration

to be a little different than the default behavior. I am working with
modwsgi and apache.

I have a project called MyProject.

I have a subdomain set up at myproject.mysite.com

the project's base url is myproejct.mysite.com/myproject
the admin is myproject.mysite.com/myprojects/admin

what I would like is myrpojects.mysite.com/admin

I don't know about the law elsewhere, but in the United States, having a
discussion with other vendors on what to charge clients opens you up to
prosecution for price fixing.  It almost certainly should be a banned topic
here.

For a fairly good description of the issue, look at the HTML Writer's Guild

I meant to mention that although I'm using InnoDB, I'm storing a copy of the
searchable text in a MyISAM table and using the MySQL search on it.  That's
okay for now, but I'm looking for clustering, faceted search and other fancy

I've worked in search-related technology for a long time and I should know
that search performance always demands lots of memory...  So I may bite the
bullet and use Solr, after all.  I just wish there were a way to trade off
the memory for speed until I'm ready to deploy a real working version.

I'm making a similar decision... as far as I can see, neither one does
search result clustering, which I'd like.  But the memory required to host
Solr means a big increase in hosting costs.  I'm using Webfaction, so to go
from their basic service to the one that offers 300 MB of memory is an
increase of about $25/month, which I'd rather not have to pay yet.

Re: How to implement this model

[Nick]

I am going to try to add better information for this issue, here we
go:

The model for the obituary looks like this:


class obit_entry(models.Model):
first_name = models.CharField('First Name', max_length=100,
blank=False)
middle_name = models.CharField('Middle Name', max_length=100,
blank=False)
last_name = models.CharField('Last Name', max_length=100,
blank=False)
nick_name = models.CharField('Nickname', max_length=100,
blank=True)
city = models.CharField('City', max_length=100, blank=False)
state = USStateField(blank=False)
occupation = models.CharField('Occupation', blank=True,
max_length=100)
date_of_birth = models.DateField(blank=False)
date_of_death = models.DateField(blank=False)
date_of_service = models.DateTimeField(blank=False)
type_of_service = models.CharField('Type of service',
max_length=100, choices=Service_Type, blank=False)
on_premises = models.BooleanField(blank=True)
service_location = models.CharField('Location of service',
max_length=100, blank=True)
service_address = models.CharField('Service Address',
max_length=100, blank=True)
service_city = models.CharField('City of service', max_length=100,
blank=True)
service_state = USStateField('State of service', blank=True)
additional_info = models.TextField('Additional Information',
blank=True)
organ_donor = models.BooleanField(blank=True)
natural_causes = models.CharField('Died of Natural causes',
max_length=100, choices=Causes_Choices, blank=False)
date_to_run = models.DateField('Date obit should run', blank=True,
null=True)
date_created = models.DateTimeField(auto_now_add=True)
date_update = models.DateTimeField(auto_now=True)
created_by = models.ForeignKey(FullProfile,
related_name="createdBY", null=True, blank=True)

the model for the business profile (FullProfile) looks like this:


class FullProfile(User):
bus_name = models.CharField('Full Business Name',
help_text='excluding type (e.g. Funeral Home, Crematorium)',
max_length=200, blank=True)
bus_type = models.CharField('Business Type', help_text='(e.g.
Funeral Home, Crematorium, etc.)', max_length=200, blank=True)
address_street = models.CharField('Street Number', max_length=200,
blank=True)
address_city = models.CharField('City', max_length=200,
blank=True)
address_zip = models.CharField('Zip Code', max_length=10,
blank=True)
phone = PhoneNumberField('Phone Number', blank=True)
contact = models.CharField('Contact Name', max_length=100,
blank=True)
bus_type_2 = models.CharField('Business Type 2', help_text='(e.g.
Funeral Home, Crematorium, etc.)', max_length=200, blank=True)
address_street_2 = models.CharField('Street Number',
max_length=200, blank=True)
address_city_2 = models.CharField('City', max_length=200,
blank=True)
address_zip_2 = models.CharField('Zip Code', max_length=10,
blank=True)
completed = models.BooleanField()
objects = UserManager()

There is an obituary form that is a model form of the obit model:

I would like to change the on_premises field to lookup of the two
business type fields in the FullProfile model so that the user can
select which business type they want to attach to the individual
obituary.

So if a business has bus_type = Funeral Home and bus_type_2 =
Crematorium, in the obituary form the user will have a drop down of
either "Funeral Home" or "Crematorium" to choose from.

How to implement this model

[Nick]

OK, here's the deal. I'm working up an obituary site. There are 3
models/tables and at one point I need to connect two in a way that is
different than I have done up to this point. Here is the situation,
any recommendations on how to accomplish this would be great:

I have an obituary table. In that table there is a field that checks
if a funeral service is on the premises (column name "on_premises" of
the Funeral Home that is entering the information.

If this BooleanField is checked then it returns the location
information of the funeral home which is stored in a business_profile
table. Not difficult, just check if the boolean returns a value and
then populate the template

That works out nicely except I have been given an extra criteria for
this project. Some business have both a funeral home and a
crematorium. Many of these situations require that we list the address
of one or the other. Since the "on premises" is a BooleanField there
is no way for someone to state what part of their business is
responsible for the service.

What I would like to do is make this option a drop down in the
obituary form that basically gives the business the option of choosing
which one of their locations is the one we want attached to this obit.
Once this is chosen then I will pull the value into the templates.

How do I relate these models? My first thought is to create two
"business type" columns in the business profile table and then relate
the "service_location" column to these columns in a drop down? Is that
even possible?

How do I retrieve the values from two different fields and then select
from them in another model?

Many thanks for your helpful posts - in the end I just changed a bit

Just to let you know, this code worked out nicely.

I made a few changes to the bottom save function:

Re: ordering integers with regroup

[Nick]

You are right, I wasn't even thinking about it like that. This is bad
news as the information is coming across as "District 45" from another
source and so I don't have just a district number to go off of. State
government data is always terrible to work with.

ordering integers with regroup

[Nick]

Has anyone come across an ordering issue with the regroup tag whereby
if the field that is being ordered is an integer you get the following
problem:

say you have the grouped field "District" and the following groupings

District 1
District 2
District 3
District 10
District 14
District 20
District 29
District 30

Their ordering will come out:

District 1
District 10
District 14
District 2
District 20
District 29
District 3
District 30

I can see why this is happening, but how do I tell the regroup tag to
sort as though 1 were 01, etc. Adding a 0 to the front isn't really an
option as their are thousands of records that reach from 1 - 250

Thanks in advance.

assigning data based on a comparison between two tables

[Nick]

I have two models. One is a list of candidates that have filed to run
for office. The second is a list of people who currently hold
office.

I'd like to compare the two tables and whenever a match is found
between the two (an entry in the candidate table shares the same
last_name and first_name with an office holder from the holds office
table) I'd like to check off a box in the Candidate table called
'incumbent'.

how would I begin to do this. They both have columns called last_name
and first_name that I can use to compare but I don't know the syntax.

I am looking for a way to identify the first item returned in a loop
and display it differently than the others:

basically it would go like:

{% for item in items %}
{% if is_first_item %}
 This is what will show
{% else %}
this is what will show
{% endfor %}

Am I overlooking something in the docs?

Upgrading Python from 2.4 to 2.6 - can I just copy site-packages folder?

[Nick]

Hi,

I'm currently running Django on CentOS using the supplied Python 2.4.
I now need to use Python 2.6.  I have installed Python 2.6 from the
EPEL repositories, which sits alongside 2.4 (which is required for
CentOS things such as "yum").

Django (and other Python modules) are all located in Python 2.4's site-
packages folder.  When I upgrade to 2.6, is it just a case of copying
these over into 2.6's site-packages folder, or do I need to install
the modules afresh?

Thanks,
Nick

 I am, but I'm not opposed to custmizing one. This part of the project

Re: If is first time logging in

[Nick]

I have an expanded user form right now. Here is the sign up process.

user registers using username, email, password

It sends and activation link to that email.

User clicks on the link and they are activated

User logs in

Here is where I would like the extended profile to pop up the first
time. When they pass through the login screen to their home page (each
user has a home page with a selection of different actions).

I can kind of see where you are going with what you have, I'm adding a
field to check to make sure the forms are finished?

I'm not too worried about users not filling out the profile, this is a
site built for submitted obituaries and the users will be funeral
homes so filling out the form is a necessary part of their job. I just
want to know how to make it really obvious to them the first time they
login.

If is first time logging in

[Nick]

I'm trying to figure out a way to see if it is a users first time
logging in after registering on the site. If it is then I will pass
them through some formsets, otherwise I let them go to their profile
page.

I tried using date_joined == last_login but that doesn't work, as the
last login date changes the second you log in.

Anyone ever done anything like this?

Any thoughts?

Re: send_mail not firing

[Nick]

Welp, indentation error:

def save(self):

needed to unindent so it was called when the form was process, instead
it was waiting for an error to trigger it, which it wouldn't do
because the error halts the form from processing.  There goes 13 hours
of my life I'm never getting back.

Re: send_mail not firing

[Nick]

It looks like the problem isn't with send_mail, its the save override
on the form, the is_active = False isn't setting that option in the DB
either, so it is skipping over the save options. Here they are again:

forms.py:
class RegisterForm(UserCreationForm):
email = forms.EmailField(label="E-Email")

class Meta:
model = User
fields = ("username", "email")

def clean_email(self):
email = self.cleaned_data["email"]

try:
User.objects.get(email=email)
except User.DoesNotExist:
return email

raise forms.ValidationError("A user with that email address
already exists.")

def save(self):
user = super(RegisterForm, self).save(commit=False)
send_activation(user)
user.is_active = False
user.save()

and the view:

def register(request):
if request.method == 'POST':
form = RegisterForm(request.POST)
if form.is_valid():
new_user = form.save()

return HttpResponseRedirect("/obits/")
else:
form = RegisterForm()

return render_to_response("obits/register.html", {'form': form })

So, the username and all of that are saving by the user.is_active and
send_mail are getting skipped

Re: send_mail not firing

Actually, I've fixed the problem with send_activation. If i go via the
form it still doesn't trigger the email.

Re: send_mail not firing

[Nick]

OK, it's all fixed. I updated the template rendering to actually use
Context, if you look at activate.py I just put "context = ({". That's
not helping anything out. I also added a default_host_email to the
settings file. I don't know if that was the problem, but I'm leaving
it in.

Re: send_mail not firing

[Nick]

I get the same results.

I dropped into the shell and tried it out

>>> user = User(username="nick", email="t...@test.com")
>>> send_activation(user)
1

I think the 1 means that it passed but I don't get any emails sent

Re: send_mail not firing

[Nick]

I get the same result.

I dropped into the shell and ran this

>>> user = User(username="test", email="t...@test.com")
>>>send_activation(user)
1

I don't really know what that 1 means, though.

send_mail not firing

[Nick]

I am having an issue with an authentication app I am writing. The app
saves the form appropriately but doesn't send the confirmation email.
I am using the same email_host settings as with other application that
send email messages but with no results. Here is the process.

First a form processes the information:

from django.contrib.auth.forms import UserCreationForm
from django import forms
from django.contrib.auth.models import User
from activate import send_activation

class RegisterForm(UserCreationForm):
email = forms.EmailField(label="E-Email")

class Meta:
model = User
fields = ("username", "email")

def clean_email(self):
email = self.cleaned_data["email"]

try:
User.objects.get(email=email)
except User.DoesNotExist:
return email

raise forms.ValidationError("A user with that email address
already exists.")

def save(self):
user = super(RegisterForm, self).save(commit=False)
send_activation(user)
user.is_active = False
user.save()

the activate.py file:

from django.core.mail import send_mail
from hashlib import md5
from django.template import loader, Context
from Obits.settings import BASE_URL as base_url

def send_activation(user):
code = md5(user.username).hexdigest()
url = "%sactivate/?user=%s=%s" % (base_url, user.username,
code)
template = loader.get_template('obits/eactivate.html')
context = ({
 'username': user.username,
 'url': url,
 })
send_mail('Activate account at super site', 'this is a test',
'myem...@mydomain.com, [user.email], fail_silently=False)


The form saves to the DB, it hits all of the conditions but fails to
send an email. I can't get any error messages so I'm really at a loss.

Re: Pluggable Q app?

[Nick]

I actually just got done writing a QandA app. It's very basic. I don't
have it open yet but I would turn over the source to you if you
wanted.

Here are the features:

Question

Answerer
Answerer's credentials
site specific QandA (using django.contrib sites)

It outputs a json api based on several filters

Re: Taking on a NoneType error

[Nick]

Well, I am embarrassed to admin that this issue was 100% user error.

I recently set up a dev and production server and copied everything
from the old production server to the two new servers.

I was testing the search results page on dev, that's the page that
generates the links to the pages that I'm having issue with (they
appear in a pop up, BTW). While the search results page was on dev the
actual page that was having the age issue was on production. So as I
edited the templates for the age pages on dev it was not updating
production so that's why i couldn't get the simple "if" statements to
work. I had full absolute URLS to the age pages, they've been changed
to relative URLS to prevent this from happening.

There is, however, a bright side to my ignorance.  The suggestions to
update the template tag filter were right on. I use this filter a lot
so it makes more since to have a built in fail safe rather than
checking in the templates each time.

Thanks a bunch,

Dummy

Taking on a NoneType error

[Nick]

I am using a custom template tag called calculate age to produce an
age in numbers based on a filter for a template tag.

Here is the tag:

def age(bday, d=None):
if d is None:
d = datetime.datetime.now()
return (d.year - bday.year) - int((d.month, d.day) < (bday.month,
bday.day))

register.filter('age', age)

here is how it is used in a template:

{{ entry.DOB|age }} # that produces an age


Here is the problem, not all of the entries in my DB have a date of
birth (henceforth known as DOB).

This raises and error.

I have tried to get around this many different ways. Here are few:

{% ifequal entry.DOB None %} N/A {% else %}  {{ entry.DOB|age }} {%
endif %}

{% ifequal entry.DOB "None" %} N/A {% else %}  {{ entry.DOB|age }} {%
endif %}

{% if entry.DOB == None #I have custom operators set up and this logic
works in the shell but not in the template %} N/A {% else %}
{{ entry.DOB|age }} {% endif %}

{% if entry.DOB == 'None' %} N/A {% else %}  {{ entry.DOB|age }} {%
endif %}

I've even tried it in my view:


def detail(request, last_name, first_name):
r = get_object_or_404(Rep, Last_Name=last_name,
First_Name=first_name)
if r.DOB == None:
r.DOB = NULLage
return render_to_response('Government/repsSingle.html', {'entry':
r, 'NULLage': NULLage})

The in the template:

{% if NULLage %}

This is a good grief sort of error and is making my brain blood boil.

Saving objects that have foreign key fields using the pk instead of an instance of the foreignkeyed object

[Nick Serra]

Sorry for the confusing title. Here is a simple example to illustrate
my question:

class Item(models.Model):
name = models.CharField()

class Manager(models.Model):
item = models.ForeignKey(Item)


On a POST I have the PK of the Item I want to link to a new instance
of the Manager object. I am saving a new Manager object that will be
linked to the Item with the PK i have. So I can do:

item_pk = request.POST.get('item')
item = Item.objects.get(pk=item_pk)
new_manager = Manager(item=item)
new_manager.save()

...but I don't like the idea of grabbing the item object first. Is
there any way to just save the new Manager object with just the PK of
the Item, thus avoiding the database call to grab the Item object?

Thanks!

Re: Paginating search results

[Nick]

The POST thing was the result of late night meltdowns and desperation.
I tend to just try stupid things when i'm working through an issue
like this, just seeing what the application is capable of doing. I've
switched it all back to GET.

I found the answer around 1 this morning.  You are exactly right, I
needed to capture the query string and place it in the "next" and
"previous" page links. Here's how I went about doing that, just in
case someone else runs into this issue:

 query_string = request.GET.copy()

and then in the dict:

'query_string': query_string.urlencode()

Re: How to define different user types?

[Nick]

Yeah, this is built in to django.

You are on the right track with user.contrib.auth. If you are doing
this all from the admin then it's as simple as creating a few groups,
giving them the permisions you want and then assigning users to those
groups.

If you are doing it on a front facing site, then there are many
template tags and view for checking permissions.

I hate to just point you at the documentation but it's pretty thorough
in this topic and without specific examples it would be difficult to
work through any examples.

Paginating search results

[Nick]

I'm trying to paginate results from a search with multiple options.
The only problem is, once I hit the next button it clears the query
and I'm left paginating all the objects in the DB.

Here is my view:

def filter_search(request):
if request.POST:
reps = Rep.objects.all()
else:
reps = []
query = request.POST
if 'q' in request.POST:
q = request.POST.get('q', '')
qset = (
Q(Last_Name__icontains=q) | Q(First_Name__icontains=1)
   )
reps = reps.filter(qset)
else:
q = []
if len(q):
qlist = q
else:
qlist = []
if 'party' in request.POST:
party = request.POST.getlist('party')
reps = reps.filter(Party__in=party)
else:
party = []
if len(party):
plist = party
else:
plist = []
paginator = Paginator(reps, 15)
results = paginator.count
try:
page = int(request.POST.get('page', '1'))
except:
page = 1
try:
repList = paginator.page(page)
except (EmptyPage, InvalidPage):
repList = paginator.page(paginator.num_pages)
finalq = request.POST
return render_to_response("Government/search.html", {
'reps': repList,
'query': query,
'plist': plist,
'qlist': qlist,
'results': results,
'finalq': finalq
})

Here is my tpl:




Democrat  
Republican 



{% if query %}
Your search for {% if qlist %} {{ qlist}} {% endif %}
{% if plist %} {% for p in plist %} {% if forloop.first %} Party
({{ p }}) {% else %} &  Party ({{p}}) {% endif %}
{% endfor %}{% endif %} returned {{ reps.paginator.count }} result(s)

{% for object in reps.object_list %}
{{ object.Position }} {{ object.First_Name }}
{{ object.Last_Name }} http://django.newsok.com/government/
reps/{{ object.Last_Name }}_{{ object.First_Name}}">view more
{% endfor %}




{% if reps.has_previous %}
Previous
{% else %}
Previous
{% endif %}


{% if reps.has_next %}
Next
{% else %}
Next
{% endif %}



That href is the cause of the problem, how do I pass a page to the url
without resetting the query?

Custom Model Fields

[Nick Taylor]

Hi all,

I want to create my own "field" type for a model, this essentially
will be a relationship to another model via a generic link model
(using GenericForeignKey etc).

As en example I basically want to do the following in models.py:

class Pizza(models.Model):
   toppings = IngredientsField()

Which can then be reused in another app sandwiches/models.py as:

class Sandwich(models.Model)
   filling = IngredientsField()

Where I use a IngredientsField() field type which then controls the
links as a separate set of models Ingredients and IngredientItems.

Now I have created in fields.py:

class IngredientsField(CharField):
def __init__(self, *args, **kwargs):
..

However I get an "Unknown column 'pizza_pizza.toppings' in 'field
list'" error - BUT I don't want to add it as a column in toppings as I
want it to be linked via the link table/model IngredientItems.
Eventually what I want to achieve is while using the admin system for
certain models that you manage there will be a text box where you can
enter ingredients into a TextField in the admin comma delimited
"Cheese, Ham" and then the model take care of the rest.

Hopefully I'm pretty close, any ideas anyone?

Thanks in advance,

Nick

Additional Text Form Field within a Models Admin Screen

[Nick Taylor]

Hi all,

I'm pretty new to Django so bare with me if this is a simple question.

Basically, I have an Article model which is simply title, body, status
etc. Now, I want to add an additional TextBox to the admin for the
model, but I don't want to add it as part of the Article model, as I
don't want to store it directly into the database as a string.

The TextBox will take an input, lets say "1, 2, 3, 4" I then want to
programmatically split this by the comma and add each item (1, 2, 3,
4) as a separate record which is a pre-existing model.

Any advice here would be greatly appreciated!

Thanks a lot,

Nick

Re: Working out some custom API stuff

[Nick]

Thanks for the help on that portion, it is working wonderfully.

I've been able to power through most of the requests for this project
but there is one outstanding element in regards to pagination.

Here is my view:


def QandAAPI(request, site):
quest = entry.objects.filter(site__name__icontains=site)
if 'id' in request.GET:
ids = request.GET.getlist('id')
quest = quest.filter(id__in=ids)
if 'sect' in request.GET:
sect = request.GET.getlist('sect')
quest = TaggedItem.objects.get_by_model(quest, sect)
if 's' in request.GET:
s = request.GET['s']
search_query = (
Q(question__icontains=s) | Q(answer__icontains=s) |
Q(answerer__icontains=s)
)
quest = quest.filter(search_query)
if 'count' in request.GET and not 'page' in request.GET:
count = request.GET['count']
quest = quest[:count]
if 'count' in request.GET and 'page' in request.GET:
page = int(request.GET['page'])
count = request.GET['count']
paginator = Paginator(quest, count)
try:
page = paginator.page(page)
except ValueError:
page = 1
json = serializers.serialize("json", quest)
return HttpResponse(json)

I am getting the following error when I try to plug a page=1 into the
URL

coercing to Unicode: need string or buffer, int found

I'm not entirely sure how to fix this error, I've tried many times.

The final view should do the following:

Check to see if 'page' and 'coutn' are part of the url. If they are,
then pull up the results of that page with the count declared in the
URL.

There will be another component that will skip the 'count' if it isn't
declared but I haven't got there yet.

Working out some custom API stuff

[Nick]

Here's the deal. I'm working on a custom API for moving information
about. I am stuck at a point in creating my view.
It might be best just to get into the details.

Here is the model:


class entry(models.Model):
question = models.CharField('Question', max_length=200,
blank=False)
answer = models.TextField('Answer', blank=False)
answerer = models.CharField("Expert's Name", max_length=100,
blank=False)
credentials = models.CharField ("Expert's Credentials",
max_length=100, blank=False)
published  = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
site = models.ForeignKey(Site)
section = TagField()

Once a site is picked the feed is narrowed down by id (whether single
id, list or range), then by section (single or multiple) and finally
some pagination and count params (I'm not worried about that right
now). Currently, I am stuck on the section portion. I may be going
about this all wrong. What I would like is for some URL like:

http://mysite.com/qanda/SITENAME/?sect=THESECTIONNAME

to produce a JSON output of Questions and Answers under that site with
that section name. Here is my view:


def QandAAPI(request, site):
quest = entry.objects.filter(site__name__icontains=site)
if 'id' in request.GET:
id = request.GET.get('id','')
id = id.split(',')
else:
id = quest.values_list('id', flat=True)
if 'sect' in request.GET:
sect = request.GET.get('sect','')
else:
sect = ''
quest = quest.filter(id__in=id, section=sect)
object = serializers.serialize("json", quest)
json = "%s" % object
return HttpResponse(json)

Basically, I would like the "else: sect=" to be a WILDCARD so if the
sect portion of the API isn't explicitly stated then it just pulls
everything.

What do you think? Raw SQL? I'm a complete bonehead? All opinions/
advice are welcome.

Re: override a form field, to allow usernames with '@'

[Nick Serra]

I just implemented this and it's a hassle. There are heated
discussions about it. I ended up modifying the auth app and completely
eliminating the 'username' field and just using email. Then I modified
the admin app to allow the login, and am basically just completely
overriding both. Good luck!

Oh, I see now.  I often forget that Django always creates its own PK with
the id.

It should be no problem to make the Django id a unique key and the composite
key from unique_together the primary key.  I can't think of any functional
way in which they are different.  But you are right, you will have to do
this manually after syncdb.  You would still define the composite index with
unique_together, so that Django knows about it.

Just make sure you make the id column, the one that Django expects to be the
primary key, a unique index.

Although I can't think of any reason this wouldn't work, I haven't actually
tried it.  A little voice is whispering that it might affect foreign keys,
but I think they only require indexes, I don't think they have to be primary
keys.  And I think you will have to do this before you add any data, or else
the FKs will make it much harder.

If you don't have data in the table, just drop it and use "unique_together"
in models.py to define your composite key.  You'll find that in the Django
docs.  Then do syncdb and Django will create the table with your composite
key.

Otherwise, you can make the change in models.py, as above, and change the PK
manually.

If there are FKs involved, you might also want to make the appropriate
changes if you're not re-creating all the involved tables with syncdb.

One other route, if you have data, is to rename the existing tables (can be
tricky with FKs), then syncdb and then copy your data... or, even easier,
create a whole new database with syncdb and copy your data into it.

Encoding makes text go away in templating; mx.DateTools.strptime v. utf-8

[Nick Arnett]

I'm stuck on a problem with encoding (or possibly decoding).

I'm extracting dates from web pages with regular expressions.  Now I want to
parse those dates into Python date objects.  Generally speaking, this is no
big deal.  It takes some effort because I'm dealing with a number of
different date formats, but I expected that.

I'm using mx.DateTime.strptime to parse the datetimes out of the strings
that I've captured with regexes.  That works fine much of the time.  It
fails when the string is utf-8 and there are characters that can't be
converted (a familiar problem).

The weird thing is that when I decode the original date string to latin-1,
Django seems to eat the entire string that I build out of that date.
Perhaps I should clarify.  I have a web page that shows me what text was
captured by the regex (so I can see that it is getting the correct chunk)
and it also shows me the output of strptime (using the pattern string for
the relevant date format).

So... when I display the parsed data via Django, there's nothing there.  But
when I add a character count for what my views.py script is sending to the
template, it shows that there is plenty of text there.  Somewhere in the
templating, that text is getting lost - it doesn't show up at all in on the
resulting page.  I know that my code is producing text because I can run it
stand-alone and see the generated text.

I don't quite even know how to figure out where it is disappearing... but
I'm hoping somebody here has seen something similar - vanishing string after
encoding...?

Thanks in advance for any insights.

Nick

P.S. As often happens, describing the problem helped a bit... it seems to be
related to mixing unicode and non-unicode strings.  When I decode the
results to utf-8, my text is back but I still can't get strptime to work
on these strings, even after decoding to latin-1, which I thought might do
it.  So frustrating that it looks like plain ascii on the page, but I can't
get it to behave like plain ascii!

Re: grabbing request while overriding save or in a signal

[Nick Serra]

Yeah, I realize this now hah. Instead I am now passing request into a
ModelForm for what I need. Basically I have a comment system, and on
each comment post I wanted to run it through Akismet, which required
the IP and User Agent. So I just passed request into my form.save()
method on comment adds. Works well. Thanks for the input though

Setting readonly_fields dynamically

[Nick]

Hi,

I would like to set some fields to be readonly in the Admin app based
on some logic, and would like to use the new readonly_fields attribute
of ModelAdmin if possible (rather than some other sort of hack).

I'm trying to access readonly_fields, but get the error "'GalleryForm'
object has no attribute 'readonly_fields'"

My code is currently as follows:

class GalleryAdminForm(forms.ModelForm):
class Meta:
model = Gallery
def __init__(self, *args, **kwargs):
super(GalleryAdminForm, self).__init__(*args, **kwargs)
print self.readonly_fields

Any help on how I can access readonly_fields from the ModelForm to
override it would be really helpful!

Thanks,
Nick

following reverse relationship of an extended model

[Nick Serra]

Hey, quick query question. I know there has to be an answer for this
one, just don't know the syntax. I need to follow the reverse
relationship for an extended model.

class Account(models.Model):
name = CharField

class Entry(models.Model):
account = ForeignKey(Account)

class Page(Entry):
name = CharField


There's my simple example. I want to get all pages that belong to
Account. account.page_set.all() does not relate, and I can do
account.entry_set.all(), but i obviously get all entries, which is a
problem because there will be many extended entry classes. Thanks in
advance!

Re: M2M Manager -- how to get primary key of join table?

[Nick Serra]

You could create a model that references the join table itself.

class ArticlePublicationsJoin(models.Model):
id = models.AutoField()
publicaiton_id = models.IntegerField()
article_id = models.IntegerField()

class Meta:
db_table = 'article_publications'

then just query on that...

query = ArticlePublicationsJoin.objects.get(publication_id='pub_id',
article_id='art_id')
primary_key = query.pk

Re: feed decorator

[Nick Serra]

Seems very odd how you're trying to implement this. Unless your
pseudocode has me confused. Can you give us the view functions too?
Seems like you're trying to use a decorator function on two views. Why
don't you just bail on the decorator, and just check for
request.GET.get('format') == 'rss', and if true kick out the rss
template instead of the html one.

Re: Track "before" and "after" state of an object when editing in the Admin?

[Nick Serra]

There are a couple ways to do this.  You can either override the model
methods like save and init, or you can use signals and tie into the
pre_save, post_save, etc. Signals are here:
http://docs.djangoproject.com/en/dev/ref/signals/

If using signals, you will have an instance of the object being saved.
Im sure there are better ways to do it, but i'd probably use the
instance variable and do a query for the original. So query for the
sender where pk=instance.pk, and compare it to the instance being
saved. Again, seems sloppy to me, im sure theres a better way.

If you're overriding the model save, you can create a copy of what you
want to compare in the init function. I just did this the other day.
For example, i wanted to check for a different title. Look at my
overridden __init__ and my overridden save and see how I copied the
title to a new variable for comparison.

class Entry(models.Model):
title = models.CharField(max_length=255)
slug = models.SlugField(max_length=255)
body = models.TextField()
user = models.ForeignKey(User)
created = models.DateTimeField(auto_now_add=True)

def __init__(self, *args, **kwargs):
super(Entry, self).__init__(*args, **kwargs)
#set current title to check for title change on save
self.current_title = self.title

def save(self, *args, **kwargs):
if self.pk: #this save is an update, not a create
if self.title != self.current_title: #new title?
#new title, update slug
self.slug = self.create_unique_slug()
else:
#created new entry, generate slug
self.slug = self.create_unique_slug()
super(Entry, self).save(*args, **kwargs)

Re: Performing an action on model.save() but not on update

[Nick Serra]

Try this out and see what happens:

def _hook_post_save_answer(instance, created, sender, **kwargs):
if created:
if instance.user:
quser = instance.user.get_profile()
quser.increment_answers()
instance.question.increment_responses()

post_save.connect(_hook_post_save_answer, sender=Answer)

Re: Performing an action on model.save() but not on update

[Nick Serra]

I didn't even think of that. It's not very common to be specifying
pk's on create anyway, so yours would probably be fine. I just think
signals are cleaner and use them when I can :)

Re: Performing an action on model.save() but not on update

[Nick Serra]

A post save signal seems better suited for this. The post save signal
has an attribute 'created' that will be true or false depending on if
the object is being created or updated. Check out the post_save
documentation: 
http://docs.djangoproject.com/en/dev/ref/signals/#django.db.models.signals.post_save

Re: New with Django

[Nick Serra]

Whenever I use django on my windows box, i use XAMPP, which is a all
in one installer that gets apache and mysql.

So I:
- install XAMPP
- install python
- svn checkout django in the site-packages folder
- install mysql bindings for python
- install python image library

and I think you need to add your python path to the windows paths

hope some of that helps.

Re: import request ? - django debugsqlshell

[Nick Serra]

Request is an object that django passes view functions that includes
post data, meta data, and data about the request taking place. Not
sure what your test function is doing, but to start, python is
complaining because you are referencing the variable before it has
been declared. You need to define request first. Your function might
need some valid request data to work. To start, just declare your
request first, request = []. Read up on django's request object here:

http://docs.djangoproject.com/en/dev/ref/request-response/

Re: temp url with time limit

[Nick Serra]

Just create a model that stores the url and the expiration time. If
the url is hit past the expiration time, delete it, if it's still
within the time limit, display whatever you want to display. Obviously
this is for a small system, since you would be waiting to delete until
the url is hit, but its quick and easy. To expand on it, make a
deletion script that purges all old urls on a set interval, say daily,
on a cron job.
