| 2021-02-19 | Fixed #32256 -- Fixed migration optimization crash when swapping field names. | Hasan Ramezani | |
| This disables optimization of RenameField operation when an old field name is referenced in subsequent operations. Co-authored-by: InvalidInterrupt <InvalidInterrupt@users.noreply.github.com> | |||
| 2020-05-28 | Fixed #31468 -- Allowed specifying migration filename in Operation. | Adam Johnson | |
| This adds also suggested filename for many built-in operations. | |||
| 2020-04-22 | Fixed #31499 -- Stored ModelState.fields into a dict. | Simon Charette | |
| This allows the removal of its O(n) .get_field_by_name method and many other awkward access patterns. While fields were initially stored in a list to preserve the initial model definiton field ordering the auto-detector doesn't take field ordering into account and no operations exists to reorder fields of a model. This makes the preservation of the field ordering completely superflous because field reorganization after the creation of the model state wouldn't be taken into account. | |||
| 2020-04-10 | Refs #28305 -- Consolidated field referencing detection in migrations. | Simon Charette | |
| This moves all the field referencing resolution methods to shared functions instead of duplicating efforts amongst state_forwards and references methods. | |||
| 2020-04-09 | Replaced ModelTuple by a model resolving function and bare tuples. | Simon Charette | |
| ModelTuple made handling of app_label=None easier but it isn't necessary anymore. | |||
| 2020-04-09 | Replaced Operation._get_model_tuple() by ModelTuple.from_model(). | Simon Charette | |
| This method predated the introduction of ModelTuple and had a single use. | |||
| 2020-04-09 | Made Operation.references_model/references_field require app_label. | Simon Charette | |
| This will allow them to drop a ton of logic to deal with null app_label. | |||
| 2020-04-09 | Refs #22608 -- Made app_label required when optimizing migrations. | Simon Charette | |
| This paved the way for the removal of lot of logic when app_label was not specified. | |||
| 2020-04-07 | Refs #29000 -- Restored delayed model rendering of RenameField. | Simon Charette | |
| Non-delayed rendering is unnecessary and wasteful now that state models relationship consistency on delayed reload is ensured. This partly reverts commit fcc4e251dbc917118f73d7187ee2f4cbf3883f36. | |||
| 2020-02-04 | Simplified imports from django.db and django.contrib.gis.db. | Nick Pope | |
| 2018-07-11 | Removed in_between from Operation.reduce()'s signature. | Simon Charette | |
| It isn't used since FieldOperation.references_model() takes into account models referenced by the field it's operating on. | |||
| 2018-07-11 | Allowed RemoveField operations to be optimized through. | Simon Charette | |
| 2018-07-11 | Relaxed FieldOperation.references_field remote field checking. | Simon Charette | |
| 2018-07-11 | Introduced ModelTuple to remove migrations boilerplate. | Simon Charette | |
| 2018-07-11 | Fixed #26720 -- Prevented invalid CreateModel optimizations of related fields. | Simon Charette | |
| 2018-07-11 | Fixed #27768 -- Allowed migration optimization of CreateModel order. | Simon Charette | |
| Thanks Ed Morley from Mozilla for the tests. | |||
| 2018-06-15 | Fixed #29000 -- Fixed RenameModel's renaming of a M2M column when run after ↵ | Jeff | |
| RenameField. Regression in 45ded053b1f4320284aa5dac63052f6d1baefea9. | |||
| 2017-12-30 | Fixed #25817 -- Made RenameField repoint to_field/to_fields references. | Simon Charette | |
| Also updated the autodetector to assume the RenameField operation will perform the required repointing. | |||
| 2017-12-01 | Fixed #28305 -- Fixed "Cannot change column 'x': used in a foreign key ↵ | Tim Graham | |
| constraint" crash on MySQL with a sequence of AlterField or RenameField operations. Regression in 45ded053b1f4320284aa5dac63052f6d1baefea9. | |||

| 2016-05-14 | Removed unused code in AlterField.database_forwards(). | Tim Graham | |
| This code added in 107c9f545346149b03354678f53a177709edaced isn't used after 4ce7a6bc84c68406e39f48550434faeef3277eba. | |||
| 2016-03-03 | Fixed #26316 -- Factored duplicated code in model/field migration operations. | Akshesh | |
| 2016-01-23 | Fixed #24109 -- Allowed RunSQL and RunPython operations to be elided. | Simon Charette | |

| 2016-01-23 | Fixed #26064 -- Moved operation reduction logic to their own class. | Simon Charette | |
| Thanks to Markus Holtermann and Tim Graham for their 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. | |||
| 2015-02-20 | Fixed #24351, #24346 -- Changed the signature of allow_migrate(). | Loic Bistuer | |
| The new signature enables better support for routing RunPython and RunSQL operations, especially w.r.t. reusable and third-party apps. This commit also takes advantage of the deprecation cycle for the old signature to remove the backward incompatibility introduced in #22583; RunPython and RunSQL won't call allow_migrate() when when the router has the old signature. Thanks Aymeric Augustin and Tim Graham for helping shape up the patch. Refs 22583. | |||

| 2014-11-28 | Fixed #23894 -- Made deconstruct methods favor kwargs over args | Markus Holtermann | |
| 2014-11-22 | Revert "Fixed #23892 -- Made deconstructible classes forwards compatible" | Carl Meyer | |
| This reverts commit f36151ed169813f2873e13ca9de616cfa4095321. Adding kwargs to deconstructed objects does not achieve useful forward-compatibility in general, since additional arguments are silently dropped rather than having their intended effect. In fact, it can make the failure more difficult to diagnose. Thanks Shai Berger for discussion. | |||
| 2014-11-22 | Fixed #23892 -- Made deconstructible classes forwards compatible | Carl Meyer | |
| 2014-11-20 | Fixed #23844 -- Used topological sort for migration operation dependency ↵ | Patryk Zawadzki | |
| resolution. This removes the concept of equality between operations to guarantee compatilibity with Python 3. Python 3 requires equality to result in identical object hashes. It's impossible to implement a unique hash that preserves equality as operations such as field creation depend on being able to accept arbitrary dicts that cannot be hashed reliably. Thanks Klaas van Schelven for the original patch in 13d613f80011852404198dfafd1f09c0c0ea42e6. | |||
