It doesn't work because that code isn't getting run at all, as you'll see if 
you put debugging into it.

save_model is an admin method, on the ModelAdmin class. It's not a method on 
the model class, and won't work outside of the admin. Tom has already given 
you the correct solution.

Thanks for your reply. But I found out about save_model().

But that seemed to be half the story. 

class Post(models.Model):
def save_model(self, req, obj, form, change):
if self.author is None:
self.author = req.User

Doesn't seem to do the trick. I'm getting error reports telling me author_id 
can't be null.
And indeed if  I look in my mysql database I see a author_id column and no 
author column. Makes sence since author is of the type models.ForeignKey().

Anyway how do I get around this ?

Authentication Framework Question

I have an application and I have figured out how to always send an
unauthenticated user to the login screen, no matter what screen they
try to enter when they're unauthenticated. First let me say that I
have not finished reading all of the documenation on the
authentication framework yet, so if the answer to the following
question is there, I apologize. Just let me know that. My question is
is it possible to redirect the user, after they login, back to the
original screen that they tried to enter before they logged in? If so
can you show me an example, point me to documentation, or otherwise
explain how? Thanks.

when exactly Django send request_finished signal please?

If I have in cache some temporary data, is it safe to clear them by
function connected to request_finished signal? (i suppose that
template was rendered, view and all middleware code was executed,
etc..; in short, everything which could touch cached values. we are

really difficult issue for sorting a callable for a list_display

2011-02-15 Thread Dan Kirkland

I have two models:

callrecords
and
callbackrequest

Callrecords stores details of a customer.
Callackrequest stores dates and times of when we need to call the
customer back

So, if a customer calls we create a record in callrecords.  The
callrecords admin interface also has
  inlines = [CallBackInline]
This means the user can enter customer details for the callrecords
data as well as call back requests within the same page.

Now, the list_display for callrecords uses a callable to fetch the
last callback record (based on date of call back required):

   # next_call_back_due will return the maximum date/time for any
callbacks that exist against the customer
def next_call_back_due(self, obj):
# max_call_record =
CallBackRequest.objects.filter(CallRecord.id =
obj.id).filter(call_back_date=CallBackRequest.objects.filter(CallRecord.id=obj.id).aggregate(Max('call_back_date'))
['call_back_date__max'])
# callback_date = max_call_record.call_back_date
  call_records =
CallBackRequest.objects.filter(CallRecord=obj.id).order_by('-
call_back_date')
  if call_records.count() > 0:
  return call_records[0].call_back_date
  else:
 return None
# return callback_date


list_display = ('number', 'call_date', 'call_back_required',
'next_call_back_due')


the problem is, I really, really need the next_call_back_due date to
be sortable for the user - or at least if it can't be sortable by the
user, then the entire list should be ordered based on the
next_call_back_date.

I have tried a few things, including:
next_call_back_due.admin_order_field = 'call_back_date'

But that doesn't work.

This feature is really important for the users so any help would be
hugely appreciated.

Snipped of the models:

class CallBackRequest(models.Model):

CallRecord = models.ForeignKey(CallRecord, null=True)
call_back_date = models.DateTimeField(null=True, blank=True)
user = models.ForeignKey(User, null=True, blank=True)

class CallRecord(models.Model):

number = models.CharField(max_length=18, help_text="Please set to
the CLI of the premise  where Broadband is to be provided.")
call_date = models.DateTimeField(auto_now=True)
call_back_required = models.BooleanField(blank=True, default=True)

Re: Django User Permissions

On 15/02/11 17:31, hank23 wrote:
> So my question is what type of object is returned by user.user_permissions?

First, N.B. you probably want to look at user.get_all_permissions().
user_permissions in particular doesn't represent all permissions a user
"has" in the django.contrib.auth system, only ones granted directly to
the user, not ones they have e.g. by way of group membership.

Anyway, to answer your question: User to Permission is a ManyToManyField

http://code.djangoproject.com/browser/django/trunk/django/contrib/auth/models.py#L218

There's involved stuff going on underneath for all such fields, but you
don't usually have to think about it - user.user_permissions winds up
being a specialized sort of Manager, with the usual manager methods -
user.user_permissions.all() etc. So the django docs for managers and
related fields apply:

http://docs.djangoproject.com/en/1.2/topics/db/managers/
http://docs.djangoproject.com/en/1.2/ref/models/relations/

> Or alternatively how can I code type check logic to figure out
> what type it is?

Python has various builtins, type(some.thing) among them.(and
dir(some.thing) will list an object's attrs). Refer to python docs, there.

But you might also want to install ipython if you haven't already. It
provides a more full-featured interactive repl for python, that django
`./manage.py shell` will pick up and use automatically if present. Then
you can just type `some.thing?` at the shell find out all sorts of stuff
about some.thing, and have get tab completion of obj attrs and such.

Trouble Understanding best approach for using django authentication

2011-02-15 Thread Jeremiah

I'm struggling with getting/understanding the best approach for using
the authentication tools that come with Django.  I'm taking the
approach of writing my own form and my own view.  My form displays and
accepts input, but I'm not getting expected results once the "login"
button is clicked.  I'm sure I'm just not doing something exactly
right...

urls.py line:
(r'^accounts/login/$', login_page),
**
views.py line:
def login_page(request):
if request.method == 'POST':
form = LoginForm(request.POST)
if form.is_valid():
username = form.cleaned_data['email']
password = form.cleaned_data['password']
user = authenticate(username=username, 
password=password)
if user is not None:
if user.is_active:
login(request, user)
else:
raise forms.ValidationError("Inactive 
user.")
else:
raise forms.ValidationError("Invalid login 
credentials.")
else:
form = LoginForm()
variables = RequestContext(request, {'form': form})
return render_to_response('accounts/login.html', variables)
**
forms.py:
from django import forms
from django.contrib.auth.models import User

class LoginForm(forms.Form):
email   = forms.CharField(label=u'Email Address')
password= forms.CharField(
label=u'Password',
widget=forms.PasswordInput()
)
**

So when I go to the form url in the browser, I punch in some
information and click "login".  I see the exception for invalid
credentials.  What I'm not sure is...

Should I be raising an exception?
What is the correct way to inform of bad credentials?

I was looking at this url as inspiration:
http://docs.djangoproject.com/en/1.2/topics/auth/#authentication-in-web-requests

Can someone help guide me towards my obvious blunder?  (and maybe give
this beginner some pointers on custom auth views/forms vs using
default?)

Thank you,
Jeremiah

looking for an experienced developer who knows Python and Django Very
well, but can also help me learn more general programming concepts, as
well as working with databases and web servers . If you happen to know
some JavaScript that'd be great - I need to use some for the front

Django User Permissions

I'm trying to get used to working with django's user authentication
framework and want to display the permissions for a user I've created.
When I try to display the the permissions that I get back from
user.user_permissions I had assumed that something like a list would
be returned and be iterable, but it's neither. So my question is what
type of object is returned by user.user_permissions? Or alternatively
how can I code type check logic to figure out what type it is? Thanks

Re: ID of each request

2011-02-15 Thread Cal Leeming [Simplicity Media Ltd]

Well, as long as you are doing things correctly, then Python will be thread
safe and thus you can place a "global" definition in your middleware (global
grequest; grequest=request), then create a function which does "global
grequest; return grequest". I have used this method for quite some time, and
it has proven sound so far. This should also work incrementing values.

If you want the incremented value to be across multiple deployments, you
could use memcached (which supports atomic operations), then do grequest_inc
= cache.incr('grequestcount', 1).

Hope this makes sense!

Two ways:

1) Pass the form which is creating/modifying this object the current
request. It can then use the request object in the save() method to
populate the field. Eg:

class FooForm(forms.ModelForm):
  def __init__(self, *args, **kwargs):
self.request = kwargs.pop('request')
super(FooForm, self).__init__(*args, **kwargs)
  def save(commit=False):
foo = super(FooForm, self).save(commit=False)
if not foo.user:
  foo.user = request.user
if commit:
  foo.save()
return foo

Even better would be to not pass around an opaque object which has
magic data in it - if you need the current user to correctly create
objects, then pass the user to the form which creates the objects.

2) At the start of each request, store the current request in thread
local storage[1], so that it is globally available everywhere.

You may have noticed I can knock out the implementation to 1) from
rote, this is because this is the correct way of doing it. It's
harder, more work, and doesn't 'just work', but it means you haven't
tied your models to only working within the context of a web request.
For instance, if you went the thread local route, and you wanted to
run a management command to import data, you would have to prep thread
local storage with a dummy 'request' object, providing the 'current
user' to your scripts.

Accessing the HttpRequest object from a model

2011-02-15 Thread Jonas Geiregat

I have a model

from django.contrib.auth.models import User

class Post(models.Model):
with_some_properties = model.CharField(max_length=1)
author  = models.ForeignKey(User)

def clean(self):
if self.author is None:
self.author = 


When a post is saved I would like to bind the current logged in user the the 
self.author field in the clean method.
How could I accomplish this ?

Regards,

Jonas.

Model Does Not Insert Record; Instead Updates Multiple Records With Date

2011-02-15 Thread octopusgrabbus

My problem is I create a model object and then save it. The data I put
in the model, which is not added. Instead an update of all similar
part numbers with the date occurs. I know about the override that
forces an insert. Is that what I should do?

Here is a sample of the data:
part_num,"ept_type","inv_id","load_date"
VWP-1602-201,43,80556338,"2011-02-15"   
I'm

Here is the web template:

 {% extends "base.html" %}

{% block content %}
Load Single Inventory Unit 

{% if errors %}
{% for error in errors %}
{{ error }}
{% endfor %}

{% endif %}

 {% csrf_token %}
Inventory Part Number:           


Inventory Type:              
         


Inventory Serial Number (ID): 



AMR Application Main Page
{% endblock content %}

Here is the view subroutine to handle the request from the web page
(partial listing):

from amr.inventory_add.models import EptInv

from funcs import *

from util_lib import *
from util_class_lib import *

def load_inv(request):
errors = []
if request.method == 'POST':
if not request.POST.get('part_num', ''):
errors.append('Please enter a valid inventory part
number.')
else:
if not request.POST.get('ept_type', ''):
errors.append('Please enter a valid inventory type.')
else:
requested_serial_number =
request.POST.get('inv_id', '')

try:
temp_ept_id =
EptInv.objects.get(inv_id=requested_serial_number)
errors.append('Endpoint is present in
inventory.')

except ObjectDoesNotExist:
# element was not found - it is OK to add to
database.
gd = createGlobalData(getMySQLDateTime())
load_date = gd.getMySQLDate()
inv_obj = \
 
EptInv(part_num=request.POST.get('part_num'), \
 
ept_type=request.POST.get('ept_type'), \
 
inv_id=request.POST.get('inv_id'), \
   load_date=load_date)
inv_obj.save()

  Here is the model:

from django.db import models

class EptInv(models.Model):
part_num = models.CharField(max_length=60, blank=True)
ept_type = models.IntegerField(primary_key=True)
inv_id = models.IntegerField(primary_key=True)
load_date = models.DateField(null=True, blank=True)

This isn't particularly well documented, best I could find is this:

http://docs.djangoproject.com/en/1.2/ref/templates/api/#rendering-a-context

Templates use '.' as a special lookup when used in a variable name.
You can use a dot to do dictionary lookup, attribute lookup, method
calls and list index lookup. What you are trying to do is the latter.

The correct way of doing it is:

{{ buchung.0.0 }}

Hi, 

 

What i want to do is show all DB-entries of a certain user.

These entries include foreign keys and i need to get the related objects
too and print them in a template

 

So what i do is this:

 

First i get all the objects that i need. 

 

buchungen = Buchung.objects.filter(Mitarbeiter = request.user.id)

 

then i want to make a list that stores lists where each of those lists
contains an object and the related objects: 

 

for buchung in buchungen:

books.append([buchung, buchung.Produkt, buchung.Aktivitaet])

 

and i pass it on to the template:

 

return render_to_response('main/index.html', {'user' : request.user,
'form' : f, 'result' : books}, context_instance=RequestContext(request))

 

Now when i try to acces that lists with

 

{{ buchung[0][0] }}

 

I get the following error:

 

Could not parse the remainder: '[0][0]' from 'buchung[0][0]'

 

How can i get acces tot hat lists ?!

Yes, by following the documentation that Tom has now linked to twice.  For 
absolute clarity, let me link you to the actual bit again:
http://docs.djangoproject.com/en/1.2/topics/forms/#using-a-form-in-a-view
This shows you exactly how to do it. Please follow it.

Just to slightly expand on what Praveen said. Static files are served
differently from templates.

Templates are loaded from views using a configured template path.

Static files are served by your web server according to its
configuration. If you are using the development web server then you
need to configure Django as Praveen suggests to set the media path.
if you are serving any other static content then you have already done
this. As and when you move to a production web server, you will need
to configure that appropriately. You should be able to leave the links
unchanged (unless you do something daft) and just configure the web
server correctly.

Cheers, Ian

Hi, 

I just want an image to be shown in my header so i just added it in my
template like this:



Unfortunately i only get the "alt text" shown and not the image. 
The image is in the same directory as the template.

Why doesn't this work ?!

RE: Saving multiple records from admin list page

2011-02-15 Thread Chris Matthews

Hi Sithembewena,

If you want to monitor changes to tables then you might also be interested in 
keeping audit/history records. See the book ProJango by Marty Alchin Chapter 11 
(page 263 onwards) and http://qr7.com/2010/10/django-simple-history-ftw/  by 
Corey Bertram

Chris

Behalf Of Sithembewena Lloyd Dube
Sent: 15 February 2011 11:17
To: django-users@googlegroups.com
Subject: Saving multiple records from admin list page

Hi all,

In my admin.py, I overrode the save() function of a model as follows:

from myproject.myapp.functions import 
send_staking_request_status_notification_email

def save_model(self, request, obj, form, change):
  staking_request = obj
  obj.save()
  send_staking_request_status_notification_email(staking_request)

Therefore, when an admin user logs in and saves a record, an email is sent off 
to a site member. The function that does the emailing is imported from a custom 
module and this works fine.

However, on the list page of said model in the admin area, the admin user is 
also able to select an action to apply to multiple records. How can I modify my 
admin.py so that the save() override specified above
fires for all records?

Thanks.

This kind of question comes up now and then.  I believe this setup
isn't recommended.  However, it's not difficult to do, either.  I
think it makes a lot of sense for someone with several small low-
traffic sites, especially where server resources are limited (say on a
shared host account).  You could accomplish this by configuring the
web server to map each domain to a different base path in the url.
For example, using lighttpd/fastcgi you would have something like
this:

#--- lighttpd.conf --
fastcgi.server = (
   "/django.fcgi" => (
"main" => ( "socket" => "/var/www/django.sock", "check-local"
=> "disable", )
   )
)

$HTTP["host"] == "site1.example.com" {
alias.url = ( "/static" => "/var/www/site1/static" )
url.rewrite-once = (
"^(/static/.*)$" => "$1",
"^(/.*)$" => "/django.fcgi/site1$1",
)
}

$HTTP["host"] == "secondsite.example.com" {
alias.url = ( "/static" => "/var/www/secondsite/static" )
url.rewrite-once = (
"^(/static/.*)$" => "$1",
"^(/.*)$" => "/django.fcgi/secondsite$1",
)
}
#-

Then you set up your django urls like this

#--- urls.py
from django.conf.urls.defaults import *

urlpatterns = patterns('',
   url(r'^site1/', include('site1.urls')),
   url(r'^secondsite/',
include('secondsite.urls')),
)

Hi,


try changing this
buchung.Mitarbeiter = 'request.user.id'

into this:
buchung.Mitarbeiter = request.user

This implies that Mitarbeiter is specified as of the type User in your model:

...
from django.contrib.auth.models import User

class Buchung(models.Model):
...
Mitarbeiter = models.ForeignKey(User)

Benedict

Re: Django Templates: Form field name as variable?

2011-02-15 Thread ju

Thank you very much for you answer

I prefer to use validation that form class provides for me...

I tried to use  but
the other problem that I have is that I can't get errors for each
field of form :(

There is another solution that I decide to use:

Saving multiple records from admin list page

Hi all,

In my admin.py, I overrode the save() function of a model as follows:

from myproject.myapp.functions import
send_staking_request_status_notification_email

def save_model(self, request, obj, form, change):
  staking_request = obj
  obj.save()
  send_staking_request_status_notification_email(staking_request)

Therefore, when an admin user logs in and saves a record, an email is sent
off to a site member. The function that does the emailing is imported from a
custom module and this works fine.

However, on the list page of said model in the admin area, the admin user is
also able to select an action to apply to multiple records. How can I modify
my admin.py so that the save() override specified above
fires for all records?

Thanks.

Hi Everyone,

Coming back weeks later, to say thank you for your contributions. I got
quite sidetracked from this task, but I should report back on this soon.

Thank you!
