Previously, if a database request spanned a related object manager, the first manager encountered would cause a request to the router, and this would bind all subsequent queries to the same database returned by the router. Unfortunately, the first router query would be performed using a read request to the router, resulting in bad routing information being used if the subsequent query was actually a write. This change defers the call to the router until the final query is acutally made. It includes a small *BACKWARDS INCOMPATIBILITY* on an edge case - see the release notes for details. Thanks to Paul Collins (@paulcollinsiii) for the excellent debugging work and patch.
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Thanks for checking it out.
All documentation is in the "docs" directory and online at http://docs.djangoproject.com/en/dev/. If you're just getting started, here's how we recommend you read the docs:
- First, read docs/intro/install.txt for instructions on installing Django.
- Next, work through the tutorials in order (docs/intro/tutorial01.txt, docs/intro/tutorial02.txt, etc.).
- If you want to set up an actual deployment server, read docs/howto/deployment/index.txt for instructions.
- You'll probably want to read through the topical guides (in docs/topics) next; from there you can jump to the HOWTOs (in docs/howto) for specific problems, and check out the reference (docs/ref) for gory details.
- See docs/README for instructions on building an HTML version of the docs.
Docs are updated rigorously. If you find any problems in the docs, or think they should be clarified in any way, please take 30 seconds to fill out a ticket here:
