a string rather than the usual level number.

templates it's not rendered using the field information, but
just using a generic "deletion_field" of the InlineModelAdmin.

This method is called only when the ModelAdmin's model is for an
ManyToManyField's implicit through model (if self.opts.auto_created).
Return True if the user has any of the given permissions ('add',
'change', etc.) for the model that points to the through model.
