2020-04-20Fixed #24559 -- Made MigrationLoader.load_disk() catch more specific ↵Jon Dufresne
ModuleNotFoundError. Avoids inspecting the exception message, which is not considered a stable API and can change across Python versions. ModuleNotFoundError was introduced in Python 3.6. It is a subclass of ImportError that is raised when the imported module does not exist. It is not raised for other errors that can occur during an import. This exception instance has the property "name" which holds the name of module that failed to import.
2020-04-10Refs #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.
2020-04-09Replaced 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.
2020-04-09Replaced Operation._get_model_tuple() by ModelTuple.from_model().Simon Charette
This method predated the introduction of ModelTuple and had a single use.
2020-04-09Made 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.
2020-04-09Refs #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.
2020-04-07Refs #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.
2020-03-25Fixed #23916 -- Allowed makemigrations to handle related model name case ↵Adam Johnson
changes. Made autodetector ignore related model name case changes so unnecessary migrations are not created.
2020-03-09Fixed #31318 -- Allowed sqlmigrate to inspect squashed migrations.David Wobrock
2020-03-09Refs #31318 -- Moved MigrationExecutor.collect_sql() to MigrationLoader.David Wobrock
collect_sql() is used only in sqlmigrate.
2020-03-02Refs #26064 -- Avoided unnecessary list slicing in migration optimizer.Simon Charette
The in_between list is only necessary if an optimization is possible.

case-insensitive. Thanks Simon Charette for the review.
2019-11-15Refs #29808 -- Optimized MigrationExecutor.detect_soft_applied().Hasan Ramezani
Use set() for iterables used only for containment checks. Simplify column checks O(n) instead of O(2n). Thanks Simon Charette for an idea.
2019-10-21Fixed #30876 -- Moved classproperty() decorator to the django.utils.functional.André Ericson
2019-10-14Fixed #30868 -- Prevented unnecessary AlterField when renaming a referenced pk.Simon Charette

2019-09-04Fixed #27910 -- Added enumeration helpers for use in Field.choices.Shai Berger
These classes can serve as a base class for user enums, supporting translatable human-readable names, or names automatically inferred from the enum member name. Additional properties make it easy to access the list of names, values and display labels. Thanks to the following for ideas and reviews: Carlton Gibson, Fran Hrženjak, Ian Foote, Mariusz Felisiak, Shai Berger.
