Tim Graham 061caa5b38 Fixed #24037 -- Prevented data loss possibility when changing Meta.managed. 
The migrations autodetector now issues AlterModelOptions operations for
Meta.managed changes instead of DeleteModel + CreateModel.

Thanks iambibhas for the report and Simon and Markus for review.

Andrzej Pragacz 72729f844e Fixed #23794 -- Fixed migrations crash when removing a field that's part of index/unique_together. 2014-11-21 10:55:19 -05:00
Patryk Zawadzki 21e21c7bc2 Fixed #23844 -- Used topological sort for migration operation dependency 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
13d613f800.

Marc Tamlyn 6ab67919ac Made nested deconstruction support both forms of deconstruct() 
Nested deconstruction should (silently) handle Field.deconstruct() as
well as other arbitrary deconstructable objects. This allows having a
field in the deconstruction of another field.

Andrew Gorcester 956bd64424 Fixed #22397 -- Issues removing M2M field with explicit through model 
Changed the migration autodetector to remove models last so that FK
and M2M fields will not be left as dangling references. Added a check
in the migration state renderer to error out in the presence of
dangling references instead of leaving them as strings. Fixed a bug
in the sqlite backend to handle the deletion of M2M fields with
"through" models properly (i.e., do nothing successfully).

Thanks to melinath for report, loic for tests and andrewgodwin and
charettes for assistance with architecture.
