Using .all() rather than .filter() results in only the base classes being returned.
The migrations created by south use the name of the field class currently, eg,
'import_status': ('repositories.models.ImportStatus', [], {'default': "'waiting'", 'max_length': '16'}),
If that ImportStatus
object is deleted (because the field is also deleted, for example) then all previous migrations will break - when running, south will give this output:
ValueError: Cannot successfully create field 'import_status' for model 'repository': 'module' object has no attribute 'ImportStatus'.
The solution is probably to return CharField
in the south tuple rather than the class itself, since CharField
won't go away and has the same semantics at the database layer.
When creating a migration with a default value specified in a new EnumField, the value is not correctly used in south.
Create a model and an initial migration with this as a field:
class Test(EnumField):
VAL = 'fish'
Then update it to:
class Test(EnumField):
VAL = 'elephant'
South's schemamigration will now fail.
