Re: djano user registration form and login(full example)

Don't even worry about factories. They're for when you want a bunch of
forms for the same model on the page at once.

Use the UserCreationForm in django.contrib.auth.forms. It only accepts
a username and password, so you can either subclass it to add the
fields or make your own form and add it to your view so that they both
appear in the same HTML form. You can validate both and do what you
need to do.

You definitely shouldn't be writing validation logic for the password
and username and such -- that's what ModelForms are for.

If you have more specific questions just ask.

djano user registration form and login(full example)

Hello,

I'm just starting with Django. I want to create a user registration form which will take input like username, password, first and last name, email, address etc.
using the same information I want to send a conformation mail to user and authenticate her/him.

I have read Django docs, from what I read either I can create a model and form separately and write authentication and other logic on my own. Other way is
to user 'formset_factory' to directly create form from model. In second case how m I going to handle password(hashing) and authentication of user?

Can Django's *auth module can be used? If yes how ?

It will be great if any one redirect me to appropriate complete example, at least to start with.

Thanx.

Re: Hey! I'm recieving an index error when trying to import models, and I can't figure out why.

Stick a print statement between lines 91 and 92 to show you model_module.__name__ .

(or use pdb if you're comfortable with it). My best guess is that the split() is returning a
list of one item. That is, that there is no '.' in model_module.__name__ . Thus an index
of -2 failss: there is no penultimate item.

At least for the time when it gets the exception. That is, you may get many lines printed,

but the last one before the exception won't have a '.'

I've been going through the tutorial and did so mostly-successfully and decided to redo it with my own code.

Everything was going fine until I decided that it would be a good idea to type from models.py import UUID, Students into the shell. With this I received the following error:

I went onto stackoverflow and found some people had similar issues a year ago, and suggested that a person delete the pyc files, which I did. It was also suggested that you make DEBUGGING = False, or True or whatever is opposite. I did this, too, only to find the same error.

I did some other things too, all to no avail... all the same error. I even checked to make sure I was saving edited files, TWICE. Still, same error.

With this, I ask for your help o' wise ones.

Thanks.

Re: Confusion about Static Files

it is very simple and doesn't require a separate http server like nginx
first you configure in settings.py the variables STATIC_ROOT and STATIC_URL, then configure http server accordingly
STATIC_ROOT is the absolute path in filesystem that stores your static files, you can put that inside django project itself if it is convenient
and then in apache use Alias and Directory accordingly

STATIC_ROOT = '/srv/django/static_files'
STATIC_URL = '/django_static/'
then in apache :
ALias /django_static/ /srv/django/static_files/
<Directory /srv/django/static_files>
Require all granted
</Directory>

I am experienced with Python but new to Django and web development in general. I am struggling to understand its static files system from the documentation. It seems like I have to set multiple settings variables and create multiple folders in order to get the server to accomplish the simple task of "finding" these files. After toying with it for a few hours I haven't been able to get the static files system to work and and have resorted to the following system which is probably a very bad idea:

In views.py:

from django.http import HttpResponse
from django.shortcuts import render_to_response
from django.template import RequestContext
import datetime
import os.path
import settings

statictypes = {".css": "text/css",
".js": "text/javascript"}

def servestatic(request, filename):
fullfilename = os.path.join(settings.STATIC_ROOT, filename)
ext = os.path.splitext(filename)[1]
return HttpResponse(open(fullfilename).read(), content_type=statictypes[ext])

And in urls.py:

from django.conf.urls import patterns, include, url
import mysite.views as views

staticextensions = [ext[1:] for ext in views.statictypes.keys()]
staticextstring = '|'.join(staticextensions)

urlpatterns = patterns('',
...
(r"([^/]+\.(?:%s))$" % staticextstring, views.servestatic)
)

This actually works (and I could optimize it by caching the static file contents in memory rather than continually rereading them), but of course it's circumventing Django's built-in system for managing static files. My project architecture looks like this:

mysite
|
|--manage.py
|--mysite
|
|__init__.py
|settings.py
|urls.py
|views.py
|wgsi.py
|--static
| |
| |--jquery.js
| |--TestFormat.css
|
|--templates
|
|--TestTemplate.html

At the beginning, the documentation page mentions, "For small projects, this isn't a big deal, because you can just keep the static files somewhere your web server can find it." This sounds like the simple solution I'm looking for; what does it mean and how do I do it? I'm also frequently confused by how when I created the project it created two nested folders with the same name. Which is considered to be the "project root"?

template composition

i read about template inheritance and think it is great
but there is the possibility of including one template output as context variable for another template
for example :

c = new RequestContest()
c['navigation'] = render_to_string('navigation.html', {'links': links})

output = render_to_response('page.html', {}, c)

and then in page.html :
<html>
<body>
<div class="navigation"> {{ navigation }} </div>
<div class="content"> ... </div>
</body>
</html>

so my question is would this method break cache or damage performance or some other problem ?

Re: Django 1.5 with uwsgi(threaded)/mysql seems to magically cache querysets

So far I don't have this issue at all with 1.4, which makes sense as it started exactly at the 1.5 upgrade time for me.

So I have some stats reports that I run that it almost seems as if each thread has its own queryset cached. Each time I refresh they change. I'm going to revert back to 1.4 due to this bug. I wish I could come up with a simple example, to demonstrate this, the problem is that the underlying database needs to change between the time each thread serves a request.
