I just started a new Django project. At the moment I haven't written any code, just some tweaks on the settings file. I am using eclipse with PyDev and when I debug the app with eclipse, whenever I try to access to http://localhost:8000/admin the debugger catches a VariableDoesNotExist exception. If I resume the debugger, the page loads properly.
I've tried running ./manage.py runserver, and then the page loads fine. It is also working on heroku.
This is a screenshot from Eclipse at the moment that the debugger stops:
I've been using Eclipse with pyDev for other Django projects and never had this problem before.
This is how my settings/base.py looks like:

I've also tried with the default value for TEMPLATE_CONTEXT_PROCESSORS.
Thank you.
How I fix it:
On the caught Exception view, right-click on the exception and then 'Ignore ...'
On PyDev > Manage Exception Breakpoints uncheck Suspend on django template render exception and make sure you don't have any of the checkboxes on the list selected.
Probably only 2 is needed, but this is what I did.

I've got this Django web app that allows users to upload various video files. The directories are all under media, and any subdirectories are created to uniquely idenfitfy the file. I already am serving static files, but all I want to do is serve the entire 'media' directory. Is there any simple way that I can server this?

It depends on what you want to do with it. For something simple like dating the file, you can set upload_to to %Y/%m/%d. You can also write a function to return a relative URL as a string, like such:
def widget_file_name(instance, filename):
return '/'.join(['widget', instance.user.username, filename])
class Widget(models.Model):
name = models.CharField(max_length=200)
user = models.ForeignKey(User)
file = models.FileField(upload_to=widget_file_name)
UPDATE
If you're just looking for a way to serve that media directory, you could always just specify it as your MEDIA_ROOT in settings.py:
MEDIA_ROOT = '/path/to/media'
Now, keep in mind, in production, you should let your web server (nginx, apache, etc) serve static and media files, so you'll need to set that up in whatever you use as a proxy pass web server. To serve the files in this directory, you will also need to set a MEDIA_URL. MEDIA_URL = 'media' will usually suffice
I am working on a blog in Python-Django. When I run the command "python manage.py runserver" in my project folder, I get following error:
Traceback (most recent call last):
File "manage.py", line 6, in <module>
server = request.META.get('wsgi.file_wrapper', None)
AttributeError: 'module' object has no attribute 'META'
I have not seen this error anywhere. Should I include Meta class in my installed_apps? How do I do it?
Here is my manage.py:

This is really a big code bulder.
This piece of code here makes no sense inside the manage.py
from django.http import request
server = request.META.get('wsgi.file_wrapper', None)
if server is not None and server.__module__ == 'django.core.servers.basehttp':
print('inside dev')
Perhaps you copied it from somewhere, and didn't put it where it belongs.
This piece of coude would belong in a view. It will never work inside manage.py, and makes asolutely no sense there.
[EDIT]
ALSO, in a view, you should NOT include the import, or you'll get the same error. That means, don't include this from django.http import request
What is the proper way to import a custom backend in settings.py? I currently have the following in settings.py:
AUTHENTICATION_BACKENDS = ('apps.apployment_site.auth.CustomAuth')
where apployment_site is the app, auth is file name, and CustomAuth is the class name.
In my view, I get: ImportError: a doesn't look like a module path after I run the following code:
from django.contrib.auth import authenticate
from apployment_site import *
authenticate(username="username", password="password")
Here's my full settings.py:

make sure it's a tuple:
AUTHENTICATION_BACKENDS = ('apps.apployment_site.auth.CustomAuth',)
note the comma at the end
I don't think you need to actually import it into your view. According to the documentation, Django will go through all your authentication backends when you call authenticate().
Thus, just make sure you have all the authentication backends you want in your settings.py.
I'm new to both Python and Django and am struggling with what I'm sure is a very simple thing. I'm using PyCharm as my ide and am attempting to follow quickstart guide [here][1]. I setup a virtual env as per the tutorial.
The project is "DjangoProjectApp" and the app is "Lunch"
With the files shown below and a browser pointed to http://localhost:8000/admin/ I get the error:
ImportError at /admin/
No module named 'DjangoProjects.Lunch'
But if I comment out the second url route in urls.py then it works. What is the correct way for me to import this module? Thanks.

# url(r'^$', 'DjangoProjects.views.home', name='home'),

Replace that line with :

There is no need to specify the name of the project. You should start from the app name.
Also, make sure Lunch is in the INSTALLED_APPS in the settings file.
I have a project in Django 1.5 and hosts it on Heroku.
The problem is that I do not see the server static files (CSS, JS) (on the user and administrator) - went through the tutorial available at: https://devcenter.heroku.com/articles/django-assets
