如何获得在相同域上运行，共享用户数据库，但具有不同（和隔离）应用程序模型的任意数量的django应用程序？

Question

I am trying to decide how to implement this architecture. I have a base Django package, let's call it BaseApp. I have been developing this for distribution as a tool for others to use. BaseApp defines some view behavior and some base models, mostly. A developer can install BaseApp, and then make another app, let's call it NeatThing, that only has to define a few models and templates, and BaseApp does the rest, and for very little effort they now have a mini-application that Does Their Neat Thing. Repeat x 100, and we have 100 different developers doing 100 different Neat Things. And they all work just peachy as separate servers in separate environments, etc.

Now I want to take that and provide 1 version of BaseApp, and 1 database of users, and all 100 different Neato-Whiz-Bang applications, and serve them together on one domain, so users all come to the same place.

How do I do that so that:

1. 1 URL points to one of the 100 different applications (programmatically in a way I configure)
2. ensure the 100 different applications are isolated from each other (can't interact with each other at all)
3. give each application (limited) access to the User database so that users can be associated with the models in their application (I am aware of Django multi-database support - but how can I secure one user database while giving each application access?)

I am asking this as a high-level implementation approach standpoint. Ie which direction do I go from here?

What you're describing sounds a lot like what postgresql tries to accomplish with schemas . See django-tenant-schemas for an excellent implement implementation of this approach in django. Disclaimer: I'm a contributor to that project.
