Hasan Ramezani 7c18b22e2f Fixed #32256 -- Fixed migration optimization crash when swapping field names.
This disables optimization of RenameField operation when an old field
name is referenced in subsequent operations.

Hasan Ramezani 8d582bf510 Fixed #32262 -- Fixed migration optimization for model creation and Meta options removal. 2020-12-18 06:57:57 +01:00
Koen De Wit 4c0b4720b0 Fixed #31954 -- Fixed migration optimization for MTI model creation with parent model with mixed case app label. 2020-08-28 13:35:13 +02:00
Adam Johnson fa58450a9a Fixed #31468 -- Allowed specifying migration filename in Operation.
This adds also suggested filename for many built-in operations.

Simon Charette 06889d6206 Fixed #31499 -- Stored ModelState.fields into a dict.
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.

Simon Charette f5ede1cb6d Refs #28305 -- Consolidated field referencing detection in migrations.
This moves all the field referencing resolution methods to shared
functions instead of duplicating efforts amongst state_forwards and
references methods.
2020-04-10 09:19:16 +02:00
Simon Charette 8b7b19f6c9 Replaced ModelTuple by a model resolving function and bare tuples.
ModelTuple made handling of app_label=None easier but it isn't necessary
anymore.
2020-04-09 10:08:06 +02:00
Simon Charette 5ca5178a78 Replaced Operation._get_model_tuple() by ModelTuple.from_model().
This method predated the introduction of ModelTuple and had a single use.
2020-04-09 10:08:06 +02:00
Simon Charette 8069526ce3 Made Operation.references_model/references_field require app_label.
This will allow them to drop a ton of logic to deal with null
app_label.

Simon Charette 25bf15c0da Refs #22608 -- Made app_label required when optimizing migrations.
This paved the way for the removal of lot of logic when app_label was
not specified.

Simon Charette ad811335bd Refs #29000 -- Restored delayed model rendering of RenameField.
Non-delayed rendering is unnecessary and wasteful now that state models
relationship consistency on delayed reload is ensured.

This partly reverts commit fcc4e251db.

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.

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 2faeb21d2f Moved _get_model_tuple() to the base Operation class.
