#30097 closed Bug (fixed)

InlineModelAdmin.has_add_permission() broke backwards compatibility by requiring obj argument

Description

InlineModelAdmin.has_add_permission() requires obj argument:

def has_add_permission(self, request, obj):
    if self.opts.auto_created:
        return self.has_view_permission(request, obj)
    return super().has_add_permission(request)

But implementation of InlineModelAdmin._has_add_permission() says obj will be required in django 3.0:

def _has_add_permission(self, request, obj):
    # RemovedInDjango30Warning: obj will be a required argument.
    args = get_func_args(self.has_add_permission)
    return self.has_add_permission(request, obj) if 'obj' in args else self.has_add_permission(request)

So, code will crush at self.has_add_permission(request) in return statement with missing 1 required positional argument: 'obj'.

This looks related to #27991. The new test case on the PR looks right and fails without the patch, so pending review I'm going to accept this as a Release Blocker on v2.1.
