NOTE: This change is backwards incompatible for some users. If you are using a 32-bit platform, you will observe no differences as a result of this change. However, users on 64-bit platforms may experience some problems using the `reset` management command. Prior to this change, 64-bit platforms would generate a 64-bit, 16 character digest in the constraint name; for example: ALTER TABLE `myapp_sometable` ADD CONSTRAINT `object_id_refs_id_5e8f10c132091d1e` FOREIGN KEY ... Following this change, all platforms, regardless of word size, will generate a 32-bit, 8 character digest in the constraint name; for example: ALTER TABLE `myapp_sometable` ADD CONSTRAINT `object_id_refs_id_32091d1e` FOREIGN KEY ... As a result of this change, you will not be able to use the `reset` management command on any table created with 64-bit constraints. This is because the the new generated name will not match the historically generated name; as a result, the SQL constructed by the `reset` command will be invalid. If you need to reset an application that was created with 64-bit constraints, you will need to manually drop the old constraint prior to invoking `reset`. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10966 bcc190cf-cafb-0310-a4f2-bffc1f526a37
Django is a high-level Python Web framework that encourages rapid development
and clean, pragmatic design.
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/modpython.txt for instructions on running Django
under mod_python.
* 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.
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
