Krzysztof Gogolewski db926a0048 Fixed #29243 -- Improved efficiency of migration graph algorithm. 2018-09-10 09:57:31 -04:00
luz.paz 97e637a87f Fixed typos in comments and docs. 2018-08-01 16:09:22 -04:00
Tim Graham c72dde41e6 Fixed #29595 -- Allowed using timedelta in migrations questioner.
Refs #29600 -- Removed usage of django.utils.datetime_safe in migrations.
2018-07-27 11:53:49 -04:00
Simon Charette 1e9b02a4c2 Refs #28862 -- Removed the FieldRelatedOptionOperation.reduce() optimization.
It isn't required anymore since AlterTogetherOperations can be reduced into
CreateModels which can reduce DeleteField operations.
2018-07-19 17:42:18 -04:00
Simon Charette fc16015de4 Fixed #26906 -- Reduced alter together operations code duplication.
Thanks Akshesh Doshi for the initial patch.
2018-07-19 17:06:01 -04:00
Simon Charette 8e3f22f251 Fixed #27731 -- Implemented CreateModel/AlterFooOperation reduction.
This should alleviate the side effects of disabling the AlterFooOperation
reduction with RemoveField to fix refs #28862 during migration squashing
because CreateModel can perform a reduction with RemoveField.

Thanks Nick Pope for the review.

Simon Charette ed7898e1b5 Fixed #28862 -- Disabled optimization of AlterFooTogether and RemoveField.
AlterFooTogether operations cannot be swapped with RemoveField operations on
the same model as they could be removing the the same field as well.

Since AlterFooTogether operations don't track what their previous value was,
it's impossible to determine whether or not the optimization is safe so the
only way to proceed is to disable the optimization.

Thanks Ramiro Morales for the in-depth analysis of the issue.

Simon Charette 8a03445885 Removed in_between from Operation.reduce()'s signature.
It isn't used since FieldOperation.references_model() takes into
account models referenced by the field it's operating on.

Simon Charette d3a935f01f Refs #27768 -- Reversed order of optimized and in-between operations.
Operations can only be optimized through if they don't reference any of the
state the operation they are compared against defines or alters, so it's
safe to reverse the order.

2016-11-06 13:53:00 +01:00
Aymeric Augustin fd748c42a9 Simplified AppConfig.import_models().
Since AppConfig now has a reference to its parent Apps registry,
it can look up the models there instead of receiving them in argument.
2016-10-28 18:43:45 -04:00
Aymeric Augustin efcb7e1ebf Modified readiness check in AppConfig.get_model(s).
It was inconsistent with the equivalent check in Apps.get_model(s)
because I made incorrect assumptions when I wrote that code and
needlessly complicated readiness checks.

This is a backwards-incompatible change.
