2017-12-22Fixed #28884 -- Fixed crash on SQLite when renaming a field in a model ↵Simon Charette
referenced by a ManyToManyField. Introspected database constraints instead of relying on _meta.related_objects to determine whether or not a table or a column is referenced on rename operations. This has the side effect of ignoring both db_constraint=False and virtual fields such as GenericRelation which aren't backend by database level constraints and thus shouldn't prevent the rename operations from being performed in a transaction. Regression in 095c1aaa898bed40568009db836aa8434f1b983d. Thanks Tim for the additional tests and edits, and Mariusz for the review.

adapt and ProgrammingError are both available on the sqlite3 module. There's no need to import the internal _sqlite3 module.
2015-05-04Allowed using the sqlite3 backend as much as possible without _sqlite3.Milan Broum
The inner import was dropped during the reorganizing of the database backends in commit 28308078f397d1de36fd0da417ac7da2544ba12d.

2015-03-25Renamed Field.rel attribute to remote_fieldAnssi Kääriäinen
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.

2015-03-21Safer table alterations under SQLiteAlex Hill
Table alterations in SQLite require creating a new table and copying data over from the old one. This change ensures that no Django model ever exists with the temporary table name as its db_table attribute.

2014-04-18Fixed #22397 -- Issues removing M2M field with explicit through modelAndrew Gorcester
Changed the migration autodetector to remove models last so that FK and M2M fields will not be left as dangling references. Added a check in the migration state renderer to error out in the presence of dangling references instead of leaving them as strings. Fixed a bug in the sqlite backend to handle the deletion of M2M fields with "through" models properly (i.e., do nothing successfully). Thanks to melinath for report, loic for tests and andrewgodwin and charettes for assistance with architecture.

This reverts commit 00e3b9a2a992ee0b7288eeeb03e7cbd52ebc6dce. It's causing a regression when tested with the proxy_model_inheritance tests.
