I want to add my field to the table user_user_group. I can add a field to table groups but I can not add a field to the many-to-many group field in the user model. I use a monkey solution for add field to groups model but it does not work for many-to-many group field in the user model.
this code work:
Group.add_to_class('type', models.IntegerField(choices=RoleType.choices, default=RoleType.ADMIN))
this code does not work:
User.groups.through.add_to_class('organization', models.ForeignKey(Organization, on_delete=models.CASCADE, null=True))
are you have any solution?
solve this solution or tell me other solution
If I were faced with this type of situation, I would create my own User model that defines its relationship with Group with a ManyToManyField using the
through parameter to specify my custom table.
I also wouldn’t try to add fields directly to the Group table, I’d create a OneToOne relationship with additional attribute fields.
(I really don’t like monkey-patches, especially when it comes to core. You never know when it’s going to come back to bite you.)
but this solution Complicates my code because I should override the Django permission manager. For example, overrides function get user groups and etc. Maybe I did not understand your solution. can Do you explain more this solution by code or another way?
is it your solution like this?
groups = models.ManyToManyField(
'The groups this user belongs to. A user will get all permissions '
'granted to each of their groups.'
user = models.ForeignKey(User, on_delete=models.CASCADE)
group = models.ForeignKey(Group, on_delete=models.CASCADE)
organization = models.ForeignKey(Organization, on_delete=models.CASCADE, null=True)
Yea, that’s the basic idea I was thinking of - I’m not immediately aware of any problems this would cause, but I could well be wrong.
excellent. I will use this solution.
