Question

I defined my custom permission through Meta Class

class Meta:
permissions = (
        ("my_permission", "My Permission"),
   )

How can I trigger an action when a new permission is inserted?

E.g., if I add a new permission called my_permission_2, I want to call an API.

Can I do it overriding save method?

Answer 1

You could do it by overiride the save method. But way of going ahead would be to use Django Signals. Using them is quite easy.

For example,

#When you try to add a new permission to a model
user.permissions.add(<new_permission>)

#This callback function would be invoked based on what event you want to fire it
@receiver(post_add, <Model_name>)
def callback(*args, **kwargs):

There are variety of events available. Take a look here
