sys.path always starts with the directory where the current script
lives - so when running './manage.py runserver', sys.path will always
starts with your project's directory. This is teh default Python
behaviour. Also and IIRC, django adds the project's parent directory
to sys.path too.

I bet you have a full import (=> 'myproject.my_app.views') somewhere
in your sources.

As far as I'm concerned, I *never* use any reference to the project's
package in my imports - this gives much more flexibility (you can
rename your project's directory, move apps outside the project's
directory etc without having to update all your imports). The only
caveat is that, when deploying with mod_wsgi, you have to make sure
you add the project's directory itself to sys.path (which is no bige
deal).

I don't thinks so, but I may be wrong. Now nothing prevents you from

IN that case I'd recommend this book:

It's very good. It says 1.1 in the title but it'll be good for any 1.x at 
least. 

If you don't want the paper version, I know Packt do ebooks too.

Re: Mudar Senha de um usuário

Hi,

If the user is logged in, instead of

user = User.objects.get(username=nome)

you can use

user = request.user

 Hello,

tracking changes of a model's attributes

[Julian]

hi,

i'm writing a little statistical app for a django-project. everytime a
very model is saved, something's stored in the db, depending on the
model's attributes. if one of the attributes changes, I have to change
the statisitical data otherwise it would leed to inconsistency. I need
to know the old value of the attribute. how do I get it?

for example: I have a model

class AModel(models.Model):
a = models.CharField(...)

class StatisticModel(models.Model):
a_value = models.CharField(...)
a_counter = mdoels.IntegerField(...)

on post_save() of a = AModel(a='a') I select the StatisticModel with
a_value = 'a' and increase a_counter by 1. If then a is saved again
with a = 'b', I have to decrease a_counter of the StatisticModel with
a_value = 'a' by 1 and increase it by 1 on another instance.

How can I do this?

Bruno, look at this line in `django/core/management/__init__.py`:

project_module = import_module(project_name)

It's importing the project. Isn't this a problem? I mean, every object
obtained from the imported project will be different from its
counterpart which was imported through an app. So what's going on?

Annotate on a FK reverse relation gives FieldError: Cannot resolve keyword

[martync]

Hi,
I am experiencing an issue on annotate function only on my production
site only when executing the code on a normal navigation (the shell
command on production has no problem).

This is the pseudo code :

# models
class Competition(model):
title = char
published = bool
date = date
discipline = FK('Discipline')

class Discipline(model):
title = char

class Photo(model);
pict = image
competition = FK(Competition)


# views
def competition_list(request, competition_id):
cs =
Competition.objects.all(published=True).annotate(photo_count=Count('photo'))
\
 .select_related("discipline").order_by('-date')
# rendering ...

This view above works fine through the command line.
When it's executed with normal http request (a browser), it causes a
field error :
---
FieldError: Cannot resolve keyword 'photo' into field. Choices are :
(...All the choices including other reversed FK...)
---
Removing the annotate() removes the error.
I checked the db Indexes and they are all correct.

My actual configuration :
Django 1.1
Postgresql 8.3
Nginx
Gunicorn

Does anybody encountered the same issue ?

That was a recent change (http://code.djangoproject.com/changeset/13498) and
is why I pointed to the 1.2 docs instead of the dev ones in answering. For
anyone using an official release, it is necessary to pass render_value=False
to get the desired behavior; for anyone using current trunk, it is not
necessary but also not harmful. For a while it will be safest for anyone
really desiring this behavior to pass render_value=False, that way the code
will work as intended on both current and older levels of Django.

Django v1.1

[Robbington]

Hey,

I keep getting this annoying problem that when I download and install
a new django package, say django-registration it reverts django from
version 1.2 to 1.1... Is there anyway to avoid this as it messes up my
databases each time for each django project I am running.

I've used a variety of methods for getting these packages,
easy_install, aptitude install, pip install all of the seem to do it..

And does any one know the best way to upgrade django back to version
1.2, do I have to delete it and start again?

Thanks

Rob

Re: Django v1.1

 Hi Robbington.

I'd suggest to use virtualenv and keep to use *only* pip
that way only you have the power to change anything
to update Django to a version above 1.2 simply
pip -E your_virtual_environment install Django>=1.2

template problem with login.html

Hi,

I built a site with django. Now i have a stupid (i couldnt understand) problem.

Everything works perfect but when i try to login and
registration/login.html is rendered, there is a margin at the top of
the login.html. And the font size increases 1 or 2 points. Font family
and other css elements remains same...

Any idea?

Re: Django v1.1

[Robbington]

Cool, thanks.

I guess I will have to start using virtualenv, it came installed with
my vps stack script, but I disabled it as I was having probs using
postgres. I guess I never gave it a great deal of time.

I just dont get why its now reverted to v1.1, its not even on my
python path, print sys.path shows only djangov1.2.egg on there..

Frustrating.

Re: template problem with login.html

style of html documents depends on browser defaults which may take

I rememer vaquely that there are browser rendering and some other

Try different browser at least.

Tying a model to a specific database using the model's meta data?

[Stodge]

I have a bunch of models and I want to specify which models (tables)
are stored on which PostgreSQL database. I've read the documentation
and I know I can use the using() function. I'm just wondering this
can't be specified in the model's meta data:

class Meta:
using = 'db_name'

or:


class Meta:
db_server = 'db_name'

Where the db_name maps to the name specified in settings.py. I'm
adding in Django support to an existing application so this would
avoid littering my code with using() function calls. I know I could
use a database router but that seems like overkill when it makes more
sense to define the database in the model's meta data. Any ideas why
this is?

Thanks

Adding username to the 500 error emails

[Chase]

I'm looking to add request.user.username to the content of the 500
error email that gets sent to settings.ADMINS. Of course, this assumes
that you're using the AuthenticationMiddleware.

I've tried the following:

 - Adding username to request.COOKIES via response.set_cookie(). This
works, but if you have several authentication mechanisms, you end up
repeating this code in various places.

 - Over-riding WSGIRequest.__repr__? No idea how this could be done.

 - Over-riding handle_uncaught_exception() in BaseHandler. Not sure
how this could be done, either.

Ideas?

RE: Adding username to the 500 error emails

[Henrik Genssen]

Hi,

add a middleware class and write a 

def process_exception(self, request, exception):

function where you send the mail yourself.
look at http://bitbucket.org/ashcrow/django-error-capture-middleware to get an 
idea,
of how to preceed errors yourself...

How to create a base form for displaying lists

[Thiago Padilha]

  Hi,

  I'm trying to create a form that is specialized in displaying a list of
items. This form should have fields/features for filtering,  paging and
sorting. Here's what I have so far :

from django import forms
from django.db import models

class ModelListForm(forms.Form):

def display_grid(self):
qs = self.queryset()
c = self.__class__
html = ['',
''.join('%s' % ''.join(['%s' % f for f
in c.__flist__])),
''.join(['%s' % ''.join(['%s' %
getattr(r, f.__name__) for f in c.__flist__ for r in qs])]),
'']
return ''.join([tag for tag in html])


def introspect(self):
c = self.__class__
if not (hasattr(c, '__model__') and hasattr(c, '__flist__')):
if hasattr(c, 'Meta') and hasattr(c.Meta, 'model'):
c.__model__ = c.Meta.model
c.__flist__ = [field for field in dir(c.Meta.model) if
isinstance(field, models.Field)]
else:
raise Exception('No metadata about the model')

def queryset(self):
self.introspect()
model = self.__class__.__model__
return model.objects.all()


This is still very poorly written and not working(hey, I just got
started), but I guess its clear what I'm trying to do: Create a generic form
that will allow me to specify a model and perhaps some visible fields. When
rendered this form will output a table to display data for that specific
model. This would allow me to create generic templates to use with generic
views for displaying lists.
So far I have a single generic view for adding/editing instances of any
model, but these views/templates depend on me writing a proper ModelForm for
each model. Since I didnt found a 'ModelListForm' for displaying lists of
items I started trying to write one of my own.
   My question : Is there any ready-to-use solution that will allow me to do
something similar? I would rather use an existing solution for something
like that.

   Thanks in advance.

custom filter -- automatically apply first option

[Julian]

hi,

I've written successfully an custom filter for the admin-interface. if
I visit

http://localhost:8000/admin/usertracking/analyze/

coming from http://localhost:8000/admin/), none of the filters is
applied, although it's marked as "selected" on the right side on the
website. the reason is probably because you have to make a request
like

http://localhost:8000/admin/usertracking/analyze/?timestamp_year__isnull=True

to apply the filter. how can i automatically apply the filter? the
solution in my mind is hooking the changelist_view-method of the admin
and manipulate request.GET.

RSS Questions

[Joel Davis]

Hello,

I am trying to set up a blog on my django-based website. I followed
the examples here:

http://docs.djangoproject.com/en/1.1/ref/contrib/syndication/

The docs are great, and it was pretty easy to set up. And it sort-of
works. But there are a couple of problems I can't figure out.

First: Autodiscovery in google reader (and others). When I put most
websites with a link rel="alternate" type="application/rss+xml" tag
into Google Reader, the reader can find the RSS feed and subscribe.
However, when I try this with my site, i get "This site doesn't have a
feed, google can auto-generate one for you.." As far as I can tell
I've followed everything that google suggests for autodiscovery, I
can't tell what's different about my setup vs. others.  I'm sure I'm
doing something basic and stupid but I can't spot it.

Secondly, I'd like to include the entire post in the RSS feed, not
just the description. Looking at other feeds, it looks like these are
stuffed into a "content:encoded" tag? Is that right? How to I get the
RSS feed to generate that?

The website is at http://www.tapnik.com/ and the feed is
http://www.tapnik.com/feeds/blog

I did notice that this was all refactored in django 1.2, I'd rather
stick with 1.1 if I can, but if this might be a lot easier in 1.2 then
I'll consider that.

Thanks for any advice!
Joel

Proto-newbie needs Django for running an app, not for dev work

[Thomas]

My first post on this list. I wish to try out a blogging app developed
in Django, called Mango, and according to its instructions I just need
to get Django installed. I'm looking for a little guidance with this.
Also, I'd like to determine just what kind of mess I've created with
my attempts at installation so far.

I'm essentially a non-programmer, though I don't mind using the
Terminal in OS X now and then, and I've learned a little PHP. I heard
Mango mentioned on the Markdown discussion list.

Steps taken so far:

1. Per instructions at mango.io/docs/, I downloaded
Django-1.2.3.tar.gz (to my desktop, since no destination was
mentioned).

2. Uploaded it to my domain via FTP. Again, since the docs mention no
destination, I put it in the same directory as my home page. I know
this is probably not the location the developers intended, but,
finding no mention of what they DO intend, I figured this location
would either cause the subsequent steps to work or harmlessly fail.

3. Consulted my host's instructions on how to open an SSH connection,
and, using Terminal, navigated to the Django file I'd uploaded.

4. Per instructions at djangoproject.com for "Installing an official
release", I ran "tar xzvf Django-1.2.3.tar.gz", changed to the new
Django directory, and ran "sudo python setup.py install". When
authentication failed (and for what reason, I have no idea, as I used
the same password), I ran "python setup.py install" instead.

5. A lot of stuff went by on the screen, and I saw that one of the
last lines said that the command to modify "python/site-packages" (OR
SOMETHING LIKE THAT, SO PLEASE DON'T QUOTE ME) had failed due to
denial of permission.

Well, my home page still is up, and I haven't received any calls or
emails from my ISP (the always-excellent Tiger Technologies, at
tigertech.net). So even though the install command made SOMETHING
happen, it appears harmless for now. But I'd really like to know what
I just did to my server and its files, not to mention my bits of MySQL
database left over from playing with WordPress and Sphider.

If nothing else comes of this, I'd like to at least point out that the
Django documentation assumes a lot of prior knowledge about these
things. It may be common knowledge for programmers, but not for
everyone who might wish to try out a Django-dependent app.

Re: Proto-newbie needs Django for running an app, not for dev work

[Brett Thomas]

Thanks for the thorough email. Hopefully somebody else can tell you more
about what you did bc I'm not that familiar with the Django internals, but
shared hosting is just hard to navigate. (I assume you are using a shared
hosting account, thus the sudo command - run as administrator - doesn't
work.) I don't think it's possible to give comprehensive instructions on how
to install Django on a shared hosting account. In my experience, they all
work pretty differently. I'd open a support ticket with your hosting
provider, and see if they have advice on how to install Django.

That said, I agree that somebody with your experience should be able to go
to djangoproject.com and learn how to install a dependent app.

Unless you have root on the server, which I suspect yo don't have since 
you're most likely have a shared hosting account, you won't be able to 
install Django that way because you won't have sufficient permissions to 
be able to install libraries into the global Python site-packages 
directory. You will need to use something like virtualenv but even then, 
it might not be possible to install Django on that particular server 
because it may not have all the dependencies you need to create a 
virtual Python environment. It's best that you use a Django-friendly 
hosting provider. The Django wiki has lots of them and you're always 
welcome to contact me off-list, too. We host Django apps we build and 
for other developers so we can get going quickly.

Re: Proto-newbie needs Django for running an app, not for dev work

[Shawn Milochik]

Django is a Python module like any other. You won't be able to install it on 
shared hosting because you won't have permissions to the package directory. You 
can easily get around this by using virtualenv.

Here are the basics you'll need:

download virtualenv

extract the tarball

do not try to install it -- run "python virtualenv.py somepath," where somepath 
is a directory where you want to install your own private Python environment.

Run: source somepath/bin/activate

You're now in your own Python environment and can install Django and anything 
else you need.

Unfortunately I'm not be able to do that trick on a TabularInline class :(,
any idea??

Re: tracking changes of a model's attributes

[Shawn Milochik]

One easy solution for this is to override the __init__() of your model
and save the values of the properties you care about in a dictionary
within your instance, such as self.orig_values.

Then, override the save() and compare the values of your model to
self.orig_values to see if they've changed.
