Anssi Kääriäinen 8f30556329 Renamed Field.rel attribute to remote_field
Field.rel is now deprecated. Rel objects have now also remote_field
attribute. This means that self == self.remote_field.remote_field.

In addition, made the Rel objects a bit more like Field objects. Still,
marked ManyToManyFields as null=True.

Anssi Kääriäinen dfadbdac6a Fixed #16426 -- deletion of 1000+ objects with relations on SQLite
SQLite doesn't work with more than 1000 parameters in a single query.
The deletion code could generate queries that try to get related
objects for more than 1000 objects thus breaking the limit. Django now
splits the related object fetching into batches with at most 1000
parameters.

The tests and patch include some work done by Trac alias NiGhTTraX in
ticket #21205.

Aymeric Augustin 4dbd1b2dd8 Used commit_on_success_unless_managed to make ORM operations atomic. 2013-03-11 15:05:05 +01:00
Aymeric Augustin 3bdc7a6a70 Deprecated transaction.is_managed().
It's synchronized with the autocommit flag.
2013-03-11 14:48:54 +01:00
Aymeric Augustin ba5138b1c0 Deprecated transaction.commit/rollback_unless_managed.
Since "unless managed" now means "if database-level autocommit",
committing or rolling back doesn't have any effect.

Restored transactional integrity in a few places that relied on
automatically-started transactions with a transitory API.
2013-03-11 14:48:54 +01:00
Aymeric Augustin 7aacde84f2 Made transaction.managed a no-op and deprecated it.
enter_transaction_management() was nearly always followed by managed().

In three places it wasn't, but they will all be refactored eventually.
The "forced" keyword argument avoids introducing behavior changes until
then.

This is mostly backwards-compatible, except, of course, for managed
itself. There's a minor difference in _enter_transaction_management:
the top self.transaction_state now contains the new 'managed' state
rather than the previous one. Django doesn't access
self.transaction_state in _enter_transaction_management.

David Cramer abbb88886b Move logic seperation as its not longer repetitive 2013-01-14 13:17:01 -08:00
David Cramer 272de9eb6b Send post_delete signals immediately
In a normal relational construct, if you're listening for an event
that signals a child was deleted, you dont expect that the parent
was deleted already.

This change ensures that post_delete signals are fired immediately
after objects are deleted in the graph.

Alex Gaynor a170c3f755 Removed some now dead code from deletion (thanks to Carl Meyer for noticing it). 2013-01-11 20:59:29 -08:00
Anssi Kääriäinen 1cd6e04cd4 Fixed #18676 -- Allow fast-path deletion of objects
Objects can be fast-path deleted if there are no signals, and there are
no further cascades. If fast-path is taken, the objects do not need to
be loaded into memory before deletion.

Thanks to Jeremy Dunck, Simon Charette and Alex Gaynor for reviewing
the patch.
