| 2020-04-21 | Refs #30591 -- Adjusted table rebuild for non-pk relationship on SQLite. | Simon Charette | |
| The existing code was only accounting for primary key changes and not all unique key fields that can be referenced. | |||
| 2020-04-21 | Fixed #31064 -- Recreated auto-created many-to-many tables on primary key ↵ | Simon Charette | |

| 2018-12-22 | Refs #30033 -- Checked constraints before committing SQLite schema changes. | Simon Charette | |
| This order of operations is more in line with SQLite's documented table rebuild procedure and ensures that changes aren't committed if foreign key integrity is broken. | |||
| 2018-12-22 | Renamed SQLite3 references to to SQLite. | Simon Charette | |
| The version suffix isn't part of the product name. | |||
| 2018-12-17 | Refs #29182 -- Stopped relying on legacy alter table semantic on SQLite 3.26+. | Simon Charette | |
| SQLite 3.26 changed the behavior of table and column renaming operations to repoint foreign key references even if foreign key checks are disabled. This makes the workarounds in place to simulate this behavior unnecessary on SQLite 3.26+. Refs #30033. | |||
| 2018-12-17 | Fixed #30033 -- Conformed to the recommended table alterations procedure on ↵ | Simon Charette | |
| SQlite3. Refs #29182. The previous implementation was following a procedure explicitly documented as incorrect and was the origin of the breakage experienced on SQLite 3.26 release that were addressed by c8ffdbe514b55ff5c9a2b8cb8bbdf2d3978c188f. Thanks to Richard Hipp for pointing out the usage of the incorrect procedure. | |||
| 2018-12-15 | Fixed #30023 -- Prevented SQLite schema alterations while foreign key checks ↵ | Simon Charette | |
| are enabled. Prior to this change foreign key constraint references could be left pointing at tables dropped during operations simulating unsupported table alterations because of an unexpected failure to disable foreign key constraint checks. SQLite3 does not allow disabling such checks while in a transaction so they must be disabled beforehand. Thanks ezaquarii for the report and Carlton and Tim for the review. | |||
| 2018-12-07 | Fixed #29182 -- Fixed schema table alteration on SQLite 3.26+. | Simon Charette | |
| SQLite 3.26 repoints foreign key constraints on table renames even when foreign_keys pragma is off which breaks every operation that requires a table rebuild to simulate unsupported ALTER TABLE statements. The newly introduced legacy_alter_table pragma disables this behavior and restores the previous schema editor assumptions. Thanks Florian Apolloner, Christoph Trassl, Chris Lamb for the report and troubleshooting assistance. | |||
| 2018-11-13 | Refs #29641 -- Refactored database schema constraint creation. | Simon Charette | |
| Added a test for constraint names in the database. Updated SQLite introspection to use sqlparse to allow reading the constraint name for table check and unique constraints. Co-authored-by: Ian Foote <python@ian.feete.org> | |||
| 2018-10-29 | Fixed #29868 -- Retained database constraints on SQLite table rebuilds. | Simon Charette | |
| Refs #11964. Thanks Scott Stevens for testing this upcoming feature and the report. | |||

| 2018-07-10 | Fixed #11964 -- Added support for database check constraints. | Ian Foote | |
| 2017-12-22 | Fixed #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. | |||

| 2015-03-25 | Renamed Field.rel attribute to remote_field | Anssi 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. | |||

| 2015-03-21 | Safer table alterations under SQLite | Alex 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. | |||
