Comment:
I couldn't reproduce this. Here's what I see after `manage.py
makemigrations && manage.py migrate`:
{{{
CREATE TABLE `t26068_user_groups` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL,
`group_id` int(11) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `user_id` (`user_id`,`group_id`),
KEY `t26068_user_groups_e8701ad4` (`user_id`),
KEY `t26068_user_groups_0e939a4f` (`group_id`),
CONSTRAINT
`t26068_user_groups_group_id_33e3cfed1d09dff9_fk_t26068_group_id` FOREIGN
KEY (`group_id`) REFERENCES `t26068_group` (`id`),
CONSTRAINT
`t26068_user_groups_user_id_308a5058396822ca_fk_t26068_user_id` FOREIGN
KEY (`user_id`) REFERENCES `t26068_user` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
}}}
I tested without migrations as well. I guess we'll need a sample project
or more details to debug it.
