I'm developing a web app using Django, and I'll need to add search functionality soon. Search will be implemented for two models, one being an extension of the auth user class and another one with the fields name, tags, and description. So I guess nothing too scary here in context of searching text. For development I am using SQLite and...
I'm trying to create a messaging system where a message's sender and recipients can be generic entities. This seems fine for the sender, where there is only object to reference (GenericForeignKey) but I can't figure out how to go about this for the recipients (GenericManyToManyKey ??) Below is a simplified example. PersonClient and Comp...

I am writing a Django application that has a model for People, and I have hit a snag. I am assigning Role objects to people using a Many-To-Many relationship - where Roles have a name and a weight.

Update 3 (Read This First) : Yes, this was caused by the object "profile" not having been saved. For those getting the same symptoms, the moral is "If a ForeignKey field seems to be getting set to None when you assign a real object to it, it's probably because that other objects hasn't been saved."

If you have DEBUG = False in your settings.py file, and you're missing the 404.html file, flatpages will generate a 500 server error instead of loading the flatpage beca...
Possible Duplicates: Use only some parts of Django? Using only the DB part of Django I want to use the Django ORM as standalone.
