问题
I have 50 different websites that use the same layout and code base, but mostly non-overlapping data (regional support sites, not link farm). Is there a way to have a single installation of the code and run all 50 at the same time?
When I have a bug to fix (or deploy new feature), I want to deploy ONE time + 1 restart and be done with it.
Also:
Code needs to know what domain the request is coming to so the appropriate data is displayed.
回答1:
The Sites framework comes to mind.
Apart from that we have Django running for multiple sites by symlinking Django to various docroots. Works like a charm, too.
回答2:
I can see two quite distinct ways to do this:
- Use one database and the sites framework. Every post/picture/whatever model is connected to a Site and you always filter on Site. This requires a separate settings file for every database.
- Use one database for each and every site. This allows different users for every site, but requires duplication of everything that is stored in the database. It also requires a separate settings file pointing to the correct database.
Either way, you do not duplicate any code, only data.

If you need to do site-specific, or post-specific changes to ie. a template, you should read up on how Django loads templates. It allows you to specify a list, ie ["story_%d.html", "story_site_%d.html", "story.html"] and django will look for the templates in that order.

I just ran into this and ended up using a custom middleware class that:
- Fetch the HTTP_HOST
- Clean the HTTP_HOST (remove www, ports, etc.)
- Look up domain in a Website table that's tied to each account.
- Set the account instance on the HTTPRequest object.
The throughout my view code I do lookups based on the account stored in the HTTPRequest objects.
Hope that helps someone in the future.
