#24237 closed Bug (duplicate)

1.7.4 requires derived ManyToManyFields to declare their internal_type as "ManyToManyField" or their add/remove migrations will do nothing

Reported by: ris Owned by: nobody
Component: Migrations Version: 1.7

According to the boffins on irc this is related to ticket #24104.

Using postgres and django 1.7.4, a custom ManyToManyField subclass that doesn't override the get_internal_type method will generate empty sql when a field add/removal migration is performed for it.

Whether or not this is desirable behaviour, it is *not* how 1.7.3 behaved and will potentially trip up a good number of people.
