Remove “add another” in Django admin screen

Question

Whenever I\'m editing object A with a foreign key to object B, a plus option \"add another\" is available next to the choices of object B. How do I remove that option?

Answer 1

Though most of the solutions mentioned here work, there is another cleaner way of doing it. Probably it was introduced in a later version of Django, after the other solutions were presented. (I'm presently using Django 1.7)

To remove the "Add another" option,

class ... #(Your inline class)

    def has_add_permission(self, request):
        return False

Similarly if you want to disable "Delete?" option, add the following method in Inline class.

    def has_delete_permission(self, request, obj=None):
        return False
