How to organize a Django project with abstract models

Question

I have several models: "Article, Video, BlogPost, News, Commodity". Each of them is in its own application.

All of them are basically the same models with several additional fields on each. But each share is about 15 fields. I am using an abstract base class . I am trying to understand how I should do this organization for this. My current setup is this:

apps/ abstract_models.py abstract_templatetags.py abstract_forms.py articles/ models.py ... videos/ models.py ... blogs/ ... 

Although I know that this is not a very good way, I just do not know where to post all the information that is shared. I do it this way, and then the application simply subclasses the form or model and makes local modifications. Since this is just a small number of changes compared to the whole picture, I think the abstract class is the way to go, but I could be wrong.

They share so much structure, but for obvious reasons, I would like to leave them separate applications. But I would like to clean it a little.

Any thoughts would be greatly appreciated.

Answer 1

I am setting up an application that I can use in different projects and call it tools . In tools , I have basic basic models that I prefer to use in different projects and import where necessary.

For example, I have CreatedModifiedModel in tools/models.py , which adds fields for creation and modification time, as well as the user who created and modified.

Once determined once, I can simply do:

 from tools.models import CreatedModifiedModel class Widget(CreatedModifiedModel): # comes with my four fields automatically 

You can create one application called base or core or tools , and then place all your abstract classes there to keep it clean and make it reusable in the future.

The Pinax project has something similar to bands. They made their base class and those that distribute it to the application.

 /apps /group base.py ... /projects models.py ... 

It seems to be great to organize. You can see their source code on github.
