making RequestContext the default context_instance

[Preston Holmes]

Is there a way to make this the default at the project level?

I see a number of tricks out there for making it easier to do within
your own views, but I'm using an auth check in django-navbar, so I
need the full context on every page, and not all reusable apps I'm
using are passing the RequestContext from their views.

As a corollary:

Should all reusable apps default to using RequestContext
context_instance in their views? If not - why not?

Re: Raise error based on both form and inline_formset

[andreas schmid]

this is my form+formset and the validation/error display works for both
at the same time.
maybe you can get yours working by comparing it


def myform(request):
idea_form =  ProjectideaForm
activity_formset = inlineformset_factory(Projectidea, Activity,
extra=5)
if request.method == 'POST': # If the form has been submitted...
form= idea_form(request.POST)
formset = activity_formset(request.POST,
instance=Projectidea()) # A form bound to the POST data
if form.is_valid() and formset.is_valid(): # All validation
rules pass
new_idea = form.save()
formset_models = formset.save(commit=False)
for f in formset_models:
f.projectidea = new_idea
f.save()
return HttpResponseRedirect(new_idea.get_absolute_url())
# Redirect after POST
else:
   form= idea_form()
   formset = activity_formset()
return render_to_response('fslform/fslform.html',
  {'form'   : form, 'formset': formset,},
  context_instance=RequestContext(request))

Re: Queryset filter on foreign key

[Mark Schuuring]

Hey Daniel,
First of all thanks a lot for your response. You understood it right
that i just want to split up the columns by the blog id so the
defintion of blogs_one and blogs_two was really helpful, thanks. So in
the shell i found out the blogs_x sort the posts. But unfortunately i
can't get it straight to let this work in the template. I worked
through the http://docs.djangoproject.com/en/dev/ref/templates/builtins/
page and used several conditioners (for / if ) which all don't work or
I applied them wrong. For now I have this

** views.py *
def blogs(request, username=None, template_name="blog/blogs.html"):
blogs_one = Post.objects.filter(blog__id=1)
global blogs_one

blogs_two = Post.objects.filter(blog__id=2)
global blogs_two

if username is not None:

user = get_object_or_404(User, username=username.lower())
blogs_one = Post.objects.filter(author=user, blog__id=1)
blogs_two = Post.objects.filter(author=user, blog__id=2)
return render_to_response(template_name, {
"blogs_one": blogs_one,
"blogs_two": blogs_two,
}, context_instance=RequestContext(request))

** Template ***

{% if blogs %}
{% trans "These are blog posts from everyone:" %}




  {% autopaginate blogs_one %}

{% for blog_post in blogs %}
{% show_blog_post blog_post %}
{% endfor %}
{% paginate %}


  {% autopaginate blogs_two %}

{% for blog_post in blogs %}
{% show_blog_post blog_post %}
{% endfor %}
{% paginate %}




{% else %}
{% trans "No blog posts yet." %}

Re: Django HTTPS and HTTP Sessions

[Carlos Ricardo Santos]

Is is possible to change the uploaded filename like:

request.FILES['file']['filename']=current.user.username+'_'+str(
current.user.id)

It says 'InMemoryUploadedFile' object does not support item assignment.

Anyway to override this?

Thanks.

Django HTTPS and HTTP Sessions

[Tony Thomas]

Hi,

I'm using Django 1.1.1 with the ssl redirect middleware.

Sessions data (authentication etc.) created via HTTPS are not
available in the HTTP portions of the site.

What is the best way to make it available without having to make the
entire site HTTPS?

GenericStackedInline max_num late binding before assigning ModelAdmin.inlines a value

[Silvano]

Hi All

I'm stuck with a seemingly simple problem. I have MyInline inherited
from GenericStackedInline that I use in several other ModelAdmins. In
some of these ModelAdmins I want to have MyInline.max_num=1 in others
I need MyInline.max_num=3.

Apparently binding locally to the class MyInline does not work (please
see simplified code below). This will make the first setting
persistent throughout all the code. Would admin.ModelAdmin.inlines
accept a list of objects of type MyInline to which I could bind to?

Any ideas on how to do this differently are much appreciated.

Thanks in advance
Silvano




file: app1.admin.py

class MyInline(generic.GenericStackedInline):
extra = 3
model = MyModel1


file: app2.admin.py

class MyAdmin2(admin.ModelAdmin):
MyInline.max_num = 1 # Obviously this will be persistent
throughout all the code
inlines = [MyInline, ]



file: app3.admin.py

class MyAdmin2(admin.ModelAdmin):
MyInline.max_num = 3 # This has no effect
inlines = [MyInline, ]

sitemap how to publish many to many field?

[Michael]

Hi there,

I am playing around with Django's sitemap app and I have a question.
When I pass a normal query in a sitemap class like Shop.objects.all()
everything works fine. My problem begins when I try to publish a model
with a many to many field in it.

When I test this code below in the Python shell everything works as I
expected. The query returns two lists. The first is a list of shops
with productgroup 'prepaid' and the second is a list of shops with
productgroup 'tv'. However, when I save the query in my sitemap.py
file and run it only the first group appears in my /sitemap.xml page.

class ShopsInProductGroup(Sitemap):
changefreq = "daily"
priority = 0.7

slug = ['prepaid', 'tv']

def items(self):
for item in self.slug:
navigation = ProductGroup.objects.get(slug=item)
shops = navigation.shop_set.all().order_by('shopname')
return shops

I guess I am doing something wrong but I can't figure out what

Re: Separate views for form display and handling

[aa56280]

First of all, any reason why you're using different views and not the
same view?

Second, yes it's possible to do what you're trying to do. Try this:

if form.is_valid():
  # do something and redirect
else:
  render_to_response('foo.html', {'form' : form'})

Re: Problems witch Apache - KeyError at / - 'HOME'

[Graham Dumpleton]

On Dec 10, 10:01 pm, edward9  wrote:

What do you mean by proper configuration? That is how Apache/
mod_python works, you can't readily change that behaviour.

If you want your Django instance to run as you rather than special
Apache user and want HOME to still be valid so you can avoid doing the
correct thing of using absolute paths rather than relying on $HOME
being set, then use Apache/mod_wsgi instead. In particular, use
mod_wsgi daemon mode and set up daemon process to run as you.

Do, disable mod_python completely, get mod_wsgi installed and work
through hello world examples in:

  http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide

In the last one with daemon process, change WSGIDaemonProcess line to:

  WSGIDaemonProcess example.com user=your-user-name group=your-primary-
group \
processes=2 threads=15 display-name=%{GROUP}

Replace 'your-user-name' and 'your-primary-group' with what you get
for user/group when you run 'id' command on command line. Eg. if:

  $ id
  uid=501(grahamd) gid=20(staff)

use:

  WSGIDaemonProcess example.com user=grahamd group=staff \
processes=2 threads=15 display-name=%{GROUP}

Modify the hello world program to:

import os

def application(environ, start_response):
status = '200 OK'
output = 'Hello World!\n'
output += 'HOME=%s\n' % os.environ['HOME']

response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)

return [output]

to verify that HOME is actually your home directory.

Once you have confirmed everything working as expect, then you can
instead set up Django.

For that see:

  http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango

Re: CSV to JSON snippet

Re: how to produce XML output from a test run?

just a note; django-test-extensions broke --verbosity. Google
Codesearch sez the fix is in there, but pip didn't have it. I'm now
patching this up internally.

other than that the package works great!

Oh, except the assertions need embellished diagnostics...

Re: Django Sites in Admin Forms

I got advice from someone in the IRC channel to do this:

Site.__unicode__ = __unicode__

And it worked.

Re: How to populate the database

I tried to convert my csv file with csv2json.py and it worked before
(see this thread

Issue with Django form when submitted using jQuery form plugin

[jul]

hi,

when submitting my form using jQuery form plugin, the request received
by the target view is different than that received when the form is
submitted in the standard way (with no javascript), and my Django
template does not render as expected. When submitted in the standard
way, the template renders the form errors (the "form.
[field_name].errors), while it doesn't when submitted via javascript.
Using the javascript submit, how can I get a request allowing to
render the template as it does using the standard submit?
The code and the diff between the request objects received in both
cases are shown below.

thanks
jul

javascript code:

*
var is_geocoded = false;
var interval;

$(function(){

$("#submit").click(function() {
var options = {
beforeSubmit:  getPosition,  // pre-submit callback
success:   showResponse  // post-submit
callback
};

// bind form using 'ajaxForm'
$('#addresto').ajaxForm(options);
});

});

function getPosition() {

var geocoder =  new GClientGeocoder();
var country = $("#id_country").val();
var city = $("#id_city").val();
var postal_code = $("#id_postal_code").val();
var street_number = $("#id_street_number").val();
var street = $("#id_street").val();
var address = street_number+", "+street+", "+postal_code+", "+city
+", "+country;

geocoder.getLatLng( address, function(point) {

if (point) {

$("#id_latitude").val(point.lat())
$("#id_longitude").val(point.lng())
is_geocoded = true;
} else {
is_geocoded = true;
}
});

interval = setInterval("doSubmit()", 500);

return false;
}

function doSubmit() {

if (is_geocoded) {
$("#addresto").ajaxSubmit();
clearInterval(interval);
}
}
*

Django template code:

*


Name:{{form.name.errors}}
{{ form.name }} 
Country:{{form.country.errors}}
{{ form.country }} 





*

Here's the difference between the request objects received by the view
with standard submit and with javascript submit:

Separate views for form display and handling

[Aaron]

I have a page with a form on it, and I want to use a separate view
function to handle the form submission and redirect to the page view.
So, the form's action would be "action="{% url views.handleform %}".

This works fine when the form has no errors; it just needs a simple
HttpRedirectResponse. However, I need a way to send the form object
back to the display page if there are any errors found in the form.

I'm actually wondering if this is even possible. Passing form objects
back to the view implies that they'd be optional arguments in the page
view function, where I'd create my own forms if none are provided.
However, it seems the only way a Django view can ever get arguments is
through either its URL string or through its keyword arguments
dictionary in the URLconf.

Is there still hope for me? :/

Re: How to populate the database

[Zeynel]

Thanks, I'll try it now. What does

os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'

do? I read the documentation here http://docs.python.org/library/os.html
but I didn't understand.

My app is in

C:.../Documents/PROJECTS/Django/sw2/wkw2.

Do I enter?

os.environ['DJANGO_SETTINGS_MODULE'] = 'sw2.settings'?
from sw2.wkw2.models import School, Lawyer

By INPUT_FILE you mean the file where data I want to upload to sqlite3
is, correct? That file is sw2/csvtest1.csv

What's 'Internal ID'?




This is my models.py:

from django.db import models

class School(models.Model):
school = models.CharField(max_length=300)
def __unicode__(self):
return self.school


class Lawyer(models.Model):
firm_url = models.URLField('Bio', max_length=200)
firm_name = models.CharField('Firm', max_length=100)
first = models.CharField('First Name', max_length=50)
last = models.CharField('Last Name', max_length=50)
year_graduated = models.IntegerField('Year graduated')
school = models.CharField(max_length=300)
school = models.ForeignKey(School)
class Meta:
ordering = ('?',)
def __unicode__(self):
return self.first


Thanks!

Cross tabulation in template

[John M]

I've got data that looks like this from a query

{'status': u'E', 'env__count': 15, 'env': u'dev'}
{'status': u'H', 'env__count': 31, 'env': u'dev'}
{'status': u'I', 'env__count': 164, 'env': u'dev'}
{'status': u'N', 'env__count': 149, 'env': u'dev'}
{'status': u'I', 'env__count': 17, 'env': u'dr'}
{'status': u'H', 'env__count': 2, 'env': u'prod'}
{'status': u'I', 'env__count': 34, 'env': u'prod'}
{'status': u'E', 'env__count': 2, 'env': u'qa'}
{'status': u'H', 'env__count': 1, 'env': u'qa'}
{'status': u'I', 'env__count': 63, 'env': u'qa'}
{'status': u'N', 'env__count': 5, 'env': u'qa'}
{'status': u'E', 'env__count': 1, 'env': u'stage'}
{'status': u'H', 'env__count': 4, 'env': u'stage'}
{'status': u'I', 'env__count': 59, 'env': u'stage'}
{'status': u'N', 'env__count': 2, 'env': u'stage'}
{'status': u'E', 'env__count': 8, 'env': u'xxx'}
{'status': u'H', 'env__count': 1, 'env': u'xxx'}
{'status': u'I', 'env__count': 38, 'env': u'xxx'}
{'status': u'N', 'env__count': 3, 'env': u'xxx'}

is there anyway to make a cross-tab output in a template?

My only solution right now is to pass in several dictionaries with
each of the status's and their counts.  Other ideas would help.

Thanks

John

Re: How to populate the database

You could also use OpenOffice with the SQLIte connector (I think)

I use Access in Windows, works great!

But you might try getting the CSV into a JSON format that the
manage.py loaddata command could use, that set's you up for the future
too.

Re: Moved server, can't log in

[Oli Warner]

I'm afraid this isn't the case for me. My sessions (if these setting does
what they're supposed to) are stored in memcached

CACHE_BACKEND = 'memcached://127.0.0.1:11211/'
SESSION_ENGINE = "django.contrib.sessions.backends.cache"

And memcached is running (there are other sites on the server).
But yes, I am using the sessions framework.

Thanks, for the advice.  I am checking it out.To clarify, my table

Re: question about changing model/table names and attributes ... (still learnin')

[Shawn Milochik]

The current best tool for this is South: http://south.aeracode.org/

You can do complicated data and database migrations smoothly, with the ability 
to roll-back changes.
I don't know why you mention changing table names, since that should never be 
necessary. But anything is possible.

If you're doing "major" changes, defined (by me) as creating a new thing (field 
or table, A.K.A. attribute or model), moving data out of an existing thing into 
it, then deleting the original thing, you'll want to carefully read and 
understand South's excellent strategy for doing this;
http://south.aeracode.org/wiki/Tutorial3

All your normal stuff, such as adding attributes to models, changing properties 
(required or not, default values, and so on) are a piece of cake with South.

question about changing model/table names and attributes ... (still learnin')

[Guy]

What is the "best practice" for editing table names or attributes
after they have been established by manage.py syncdb?

Since I am in the very early stages, I either delete the database and
create a new one with syncdb, or manually change the table names (I
generally use the SQLite manager plugin for firefox to assist with the
SQL).

Is there a better way of doing this?  Destroying the database and
building a new one works now when I only have some test entries, but I
am concerned that this would be impractical once my db is fully
populated with real data. Likewise, I want to be careful when editing
tables that contain valuable data.

Can someone point me to a good write-up of this process, or good
software?

Go easy on me, I spent my education in biology and am just getting
started trying to understand silicon rather than carbon based systems.

Thanks.
Guy

N.B. There is nowadays the X-SendFile thing, should be mentioned a fair
few times in the list archive, you can do authorization in the django

Re: How to populate the database

[Shawn Milochik]

There are different ways to do it, depending on how much data you have and how 
often you plan to do it.

The fastest way for large files is to use sqlite3's .import command to directly 
import a file. However, this will bypass any validation done by your models.

The way I do it is to read the csv with csv.DictReader, then create instances 
of my model with the values from the resulting dictionary, then calling a 
.save() on the new instance. This is fairly slow, but thorough; you won't 
realize belatedly that your database is missing required fields or has invalid 
values, because the script will just blow up if you try.

individual forms (1 loan and 6 loan items), I need to get the member
from the loan and the number of loan items from the loan items forms
then raise an error if the items already loaned + the number of new
loan items entered is greater than 6.

I can raise errors based on the form or the formset but not both
together, is this possible? What do I subclass to add the custom clean
method?


Here's my unfinished view


def loan_add_form(request,template_name='resources/
loan_add_form.html'):

loan = Loan()
LoanItemFormset = inlineformset_factory
(Loan,LoanItem,formset=LoanItemBaseModelFormSet,can_delete=False,extra=6,exclude='date_returned')

if request.method == 'POST':

loan_form = forms.LoanForm(request.POST,instance=loan)
loan_item_formset = LoanItemFormset
(request.POST,request.FILES,instance=loan)

if loan_form.is_valid() and loan_item_formset.is_valid():
loan_form.save()
loan_item_formset.save()

#request.user.message_set.create(message="Confirmation
message.")
#return HttpResponseRedirect('/somepath')

else:
loan_form = forms.LoanForm(instance=loan)
loan_item_formset = LoanItemFormset(instance=loan)

context = {
'loan_form': loan_form,
'loan_item_formset': loan_item_formset,
}

return render_to_response(template_name, context,
context_instance=RequestContext(request))

An HttpResponse can contain whatever you like - it doesn't just have
to return HTML. So you can use it quite happily to return raw JPG or
PNG or whatever you want. Just set the mimetype to the correct type
when you initialise it.

Also remember that HttpResponse is a file-like object, so you can pass
it into anything that expects to write to a file.

Here for example is a very old post by Jacob that shows how to use
this to produce dynamic graphical headlines:

We're doing something similar with generating maps.

We have a model to represent the generated map to record a hash of its
creation parameters (e.g. dimensions, points plotted) and when it was
generated. The map is then saved to a cache directory with the hash as a
filename.

We then have a simple view to serve the page:

def generated_map(request, hash):
map = get_object_or_404(Map, hash=hash)
f = open(map.get_filename(), 'r')
return HttpResponse(f, mimetype="image/png")

The alternative would be to stick an Alias in your apache conf (assuming
you're using apache) to serve the files directly from the filesystem.
This solution wouldn't let you perform any authorisation, though.

We remove out old maps when we reach some large number in the cache
directory so as not to fill up the disk.

HTH,

Alex

return a dynamically generated image to the user?

[Mark Freeman]

I have recently created a python module which parses an input string
and invokes the program lilypond to generate a music score image. All
of this works fine as a standalone python app. I'm now looking to add
this to my django site so users can enter the  text on a form, hit
submit, and have the site return the image of the music score.

The form submission part is no problem, but I am not sure where to
start with having the view return the image to the page. Anyone have
suggestions for where to start?

many permission sets for same user

[Adonis]

Hi,

I am trying to figure out the best way to do this.
I have built a django application where users are members in projects.
Thus, i need to assign users different permission sets that correspond
to different projects. The django core permission system cannot solve
this by itself. I took a look at django-autority extenion which seems
able enough to solve this but could not figure out how to do this.

{% ifhasperm [permission_label].[check_name] [user] [*objs] %}
lalala
{% else %}
meh
{% endifhasperm %}

in the example above, i can check a permission of a user in an object
(e.g a project in my app).
I would need multiple views of auth_user_user_permissions such as:
project1_user1_permset1, project2_user1_permset3 etc.

Any suggestions will be appreciated!

Re: Tricky Django tables setup

[Superman]

Awesome thanks... But then that removes the need for a Category... :
( The projects have to be linked to the Specs which are only linked to
the Category of the Project.

class ProjectSpecs(models.Models):
Project=models.ForeignKey(Project)
Specs=models.ForeignKey(Specs, ##Limit by Category of the
Project## )
Values=models.CharField(max_length=200)

You think I should write a customized function for that? I think that
may be the answer!!!

What do you guys think is it better to have more models, less columns
or less models, more columns??? Which is more efficient in the long
term?

Re: Tricky Django tables setup

[GRoby]

It sounds like you just need a ProjectSpecs Table:

class ProjectSpecs(models.Models):
Project=models.ForeignKey(Project)
Specs=models.ForeignKey(Specs)
Values=models.CharField(max_length=200)

That would let you assign as many specs to a project that you want,
with additional fields (basically a many to many relation).

Re: Tricky Django tables setup

By the way this is what the three models roughly look like.

Class Projects(model.Models):
 title = models.CharField(max_length=200)
 category = models.ForeignKey(Category)

Class Category(model.Models):
 title = models.CharField(max_length=200)
 specs = models.ManyToManyField(Specs)

Class Specs(model.Models):
 title = models.CharField(max_length=200)

Re: Tricky Django tables setup

[Superman]

Thank you DR for your response.

Yes that helps in a way, as that is what I am planning to do. But at
the moment I can store the name of Projects, Categories and Specs in
the three different models. Where can I store the values for the Specs
for each Project? There is no table that contains that information.
How can I set that table up... in a way that it can expand both
sideways and downwards?

I don't understand what you mean when you say you want to "set up a
table" with those various columns. The columns all exist in separate
tables. What would be the benefit of putting them into a single table?

Do you just mean you want to output the columns from various tables at
once? You can easily do that with Django's ORM, which is capable of
traversing the relationships between tables. You can then use the
template language to group the fields into columns for output. Does
that help?

Re: One to many mixins?

[Superman]

Can you not create another Field in SubForm 1 model? Like so:

class SubForm1(models.Model):
  def __unicode__(self):
return "SubForm1"

  Form1 = models.ForeignKey(Form1)
  Form2 = models.ForeignKey(Form2)
  ## some fields here

Tricky Django tables setup

[Superman]

Hi guys, I can't wrap my head around this problem I have... someone
please help.

The Problem: I have a list of various projects, in a Project Model.
Each of them has a foreign Key to a Category model. Each Category has
a Many to Many Relationship to a Specification model. So it is like
this. Project ---> Category --->(m2m) Specifications. All these tables
are going to change/increment. I want to set up a table with column 1
as Project, column 2 as Category and the rest of the columns as
Specification.

For ex. these are possibly two rows from the column:
Colum -> Row1
Project -> Skyrise Appartments
Category -> Residential Building
Specification -> Height - 100m
  -> Floors - 30f
  -> Cost - 50m
   -> Start - Dec 2009
   -> Finish - Dec 2010
->Rest of the columns blank

Colum -> Row 2
Project -> GreatHarbour Bridge
Category -> Bridge
Specification -> Length - 1 km
  -> Type - Cable Stayed
   -> Speed - 80 km/hr
   -> Pillars - 200
   -> Cost - 20m
   -> Start - Feb 2010
   -> Finish - Nov 2010
>Rest of the columns blank

I dont want to ceate individal tables for Each Category... coz I may
have Hundreds of Categories, Projects and Specs. How do I go about
doing this? Please help...

Thanks

Re: Retrieving a subclass instance when all you have is its parent class instance

[trybik]

Hi,

you might take a look at this snippet:
http://www.djangosnippets.org/snippets/950/

Basically it's a negative of what you want (i.e. w/o subclasses) but
the idea I guess is there: you want a custom DB manager for which
SuperClass.objects returns in fact the SubClass instances. I bet there
are thousands of complications involving efficiency, filtering or
multi-inheritance but with some simplifying assumptions I guess it's
feasible.

It looks like a fundamental ORM poroblem. I've made some research but
haven't yet found a ready-to-go solution for it in Django. Please
write how it went or maybe someone else already knows how to do it
properly?

Best regards,
Mikołaj

Are you using Django's session framework? If so, it stores session
info in the database, which you might want to clear.

the problem is that the call to reverse('app-list') is happening
_before_ the construction of the URL list.

i don't know much about Django internals, but i'd at least try
separating 'app-new' in a different call to patterns() than
'app-list'.

something like:

urlpatterns = patterns('',
   ...
   (r'^apps/$', list_detail.object_list,
{'queryset': App.objects.all()},
'app-list')),
)

urlpatterns += patterns('',
   (r'^app/new/$': create_update.create_object,
{'model': App, 'post_save_redirect': reverse('app-list')},
   'app-new'),
   ...
)


not sure if would work, thought.  it's quite possible that Django
still has work to do after the whole urls.py execution to make
reverse() work.

One to many mixins?

[Shai]

Hi all,

I'm not sure my title is correct. Here Is my problem: I want to use
the django admin for data entry into some models. The models are based
on actual paper forms. There are several forms. and they share some
fields. I would like to follow the principle of DRY when creating this
app. As an illustration, consider the following models:

class Form1(models.Model):
  def __unicode__(self):
return "Form1"

class Form2(models.Model):
  def __unicode__(self):
return "Form2"

   ## some fields here

class SubForm1(models.Model):
  def __unicode__(self):
return "SubForm1"

  Form = models.ForeignKey(Form1)
  ## some fields here


I would like to have Form2 also be linked to a SubForm1 model. How can
this be done?

Thanks,
Shai

reverse in urlpatterns

[Baurzhan Ismagulov]

Hello,

Can I use reverse() in urlpatterns, similar to the following?

urlpatterns = patterns('',
...
(r'^apps/$', list_detail.object_list,
 {'queryset': App.objects.all()},
 'app-list'),
(r'^app/new/$': create_update.create_object,
 {'model': App, 'post_save_redirect': reverse('app-list')},
'app-new'),
...
)

When I try this, I get NoReverseMatch at /apps/: Reverse for 'app-list'
with arguments '()' and keyword arguments '{}' not found.

I'd like to avoid hard-coding URLs. Is there a way to do that?

I'm aware that I could probably abuse get_absolute_url for that.
However, I'll need to implement more complex workflows where the same
URL is going to be "called" from different pages on the site and will
have to return back to the "calling" page (not unlike admin's popup
windows, albeit without popups). What is the best way to do that?

I'm using Django 1.0.

Thanks in advance,

True of classical sql, but just to note as an interesting aside - modern
databases support "common table expressions". Maintaining other reps,
materialized path etc. as you mention, still probably better (higher
perf) for many use cases, just sayin'.

CTEs are of course expressed in sql's dire syntax, but anyway in e.g.
recent postgresql this will work:

with recursive x as
(select *, 1 as lev, '.' || id::text as path
   from person where id=3
 union all
 select p.*, x.lev+1 as lev, x.path || '.' || p.id::text as path
   from person p join x on p.ancestor_id = x.id)
  select * from x;

-- there, clear as mud, person 3 and their descendants,
with generated (relative) path and level for each record.  I think.

see
http://wiki.postgresql.org/wiki/CTEReadme#Examples
http://en.wikipedia.org/wiki/Common_table_expressions

ObDjango:  No idea how you'd persuade the ORM to generate CTEs ;-)

Re: psycopg2 and "idle in transaction" messages

[Nadae Ivar BADIO]

Hi Alexander,

I wanna to ask you how do you configure django debian postgres apache and 
psycopg2
i try it but i could not have i wanan to run it on apache with svn .
Thanks

Objet: psycopg2 and "idle in transaction" messages

Hi all,

As of last Thursday we've been seeing ~100% CPU usage from Apache, which
we believe was caused by Debian Bug #528529[0], whereby psycopg2 was
attempting to double free pointers, resulting in segfaults. This was
then (we think) leaving database connections open, resulting in postgres
saying "no more connections, TYVM" and the whole site 500ing. Not good.

On Monday we worked out what was happening and pulled psycopg2 2.0.12
from PyPI, as the bugfix hasn't been backported to Debian Lenny.
Everything seemed happy, but now we're seeing similar symptoms again and
were wondering if anyone else could help.

Versionwise, we have:
 * Django 1.1
 * Python 2.5.2 (r252:60911, Jan  4 2009, 17:40:26) [GCC 4.3.2]
 * Debian Lenny
 * psycopg2 2.0.12-py2.5-linux-i686
 * postgresql 8.3.8

Here're the outputs of a few things that might be useful:
 * SELECT * FROM pg_stat_activity: http://dpaste.com/131597/
 * SELECT * FROM pg_locks: http://dpaste.com/131598/
 * The top of 'top':   http://dpaste.com/131599/
 * A bit of 'ps -Af':  http://dpaste.com/131600/
 * A screenshot of our CPU usage:  http://users.ox.ac.uk/~kebl2765/cpu.png
 * A screenshot of our load avg:   http://users.ox.ac.uk/~kebl2765/load.png

The short drops in CPU utilisation were due to apache/postgres/system
restarts, and periods of high system CPU usage were generally when it
was 500ing.

The first time round we had tracebacks and memory dumps in our
/var/log/apache2/error.log; now there's nothing useful.

Any help would be greatly appreciated!

Warm regards,

Alex

Re: Problems witch Apache - KeyError at / - 'HOME'

Ok. Probably that its. But where can i found proper configuration for
apache?
Or can U help me by pasting samples Apache configuration? I have read
some tutorials about configuration Django with Apache and mod_python
but nothing works :(

And about quotas i think this is not it. Code without quotas works
fine on dev server, but stop working on apache.

Moved server, can't log in

[Oli Warner]

A couple of days ago I moved a site from one server to another server and
changed the DNS on the domain so it stayed the same. After the DNS had
migrated everybody but me could log in. All other users trying to log into
the admin were getting the "Looks like your browser isn't configured to
accept cookies [...]" error. There's also a log in page for non-admins and
that was also just refusing to log people in.

The only way I could fix it was to set the server to redirect the users
through to a different subdomain. I would like to go back to the original
domain but I can't if it breaks (this is a business-to-business webapp - it
can't have downtime).

I've also got to move a couple more sites in the coming days but I can't
until I can figure out what happened here so I can prevent this happening
again in the future.


I need ideas... Ideally more advanced than "clear the cookies" as there are
a couple of hundred users on the system - this is vastly impractical.

Thanks in advance.

This question is also on stackoverflow (if you're a user and you think you
have the answer, you can get some points):

If you're an experienced programmer, but a Django newbie, I think there's a
good chance for you on any Django job offering. In that case I suggest you try
DjangoGigs[0].

If you don't have much experience programming you can try starting a tiny
project of your own and/or joining a small free (as in freedom) software
project that uses Django. For that you should go to Google Projects[1],
Bitbucket[2], Launchpad[3], Github[4], etc.

Quite so, I would suggest Zabbix (http://www.zabbix.com/) we have used it in
a couple of deployments now to great success.

Probably because you don't have a tty allocated when you run in the
view. You should be using something like paramiko[1] for this.

Not sure about your first error, but you are getting this second error

django-tagging - how to get current page number in a template

Firstly, we have simple template.

{% load pagination_tags %}
{% block first_column %}
{% autopaginate object_list %}
{% paginate %}

Suppose, we have "second_column", so how do I get the current page
number, number of all pages paginated, or even next/previous page
link, if it matters, exactly in other block?

Re: Problems witch Apache - KeyError at / - 'HOME'

[Graham Dumpleton]

You do understand that when running under Apache that the code runs as
a special Apache user.

So, not only would the home directory not even be that for your home
account, Apache scrubs the HOME user environment variable from the
process environment anyway, and so trying to access HOME variable will
fail.

General rule in web programming is, never to rely on user environment
variables and secondly never rely on current working directory being a
particular location nor use relative paths, always use absolute paths
instead.

Re: Format fields in list, but keep sortable?

[philomat]

Chris: Sure, there's that possibility – however, I think it would be
very bad practise to insert a redundant field like this, just for
formatting matters. Also, one might want the option of using localised
units, etc.

Shawn: Of course you are generally correct and I know that the core
developers keep reminding everyone of this fact. However, they
themselves have implemented a lot of "niceness" in the admin lists
(boolean icons, date formatting etc), so I think this trivial
formatting matter is not about going beyond the scope of the admin.
Also, rewriting the whole admin application just because you want to
format some fields in a different way would be a bit exaggerated.
Also, I don't think you have to call yourself lazy for making the most
of what's already there.

I suppose there is not a really easy way, then.
