sqlall silently ignores any fields that are a subclass of AutoField

[Michael Manfre]

A field that is a subclass of AutoField will be silently ignored in the output of manage.py sqlall

An app with a models.py containing:

class MyAutoField(models.AutoField):
    pass

class TestModel(models.Model):
    id = MyAutoField(primary_key=True, db_column='SomeID')

will output the below from sqlall for sqlite3.

BEGIN;
CREATE TABLE "testapp_testmodel" (
)
;
COMMIT;

sqlall works as expected when models.AutoField is used instead of MyAutoField.

Verified, but not 1.2 critical - this problem has existed for a while.

Fix Django 1.2 to allow subclassing AutoField

[Michael Manfre]

Added patch for Django v1.2 (up to r13444).

There is also the workaround of overriding get_internal_type in the subclass to return "AutoField" instead of self.class.name (from class Field). The issue is that the internal type is passed to the database backends so they can map the field to a database type.

class MyAutoField(models.AutoField):
    def get_internal_type(self):
        return "AutoField"

(In [13540]) Fixed #13516 -- Added an internal type definition for AutoFields, so that subclassed fields are handled correctly by the SQL generator. Thanks to manfre for the report and patch.

(In [13541]) [1.2.X] Fixed #13516 -- Added an internal type definition for AutoFields, so that subclassed fields are handled correctly by the SQL generator. Thanks to manfre for the report and patch.

Backport of r13540 from trunk.
