How do you limit the inline formset in django admin?
Problem:
I have a table A with 1 to n relationship with B. Table A should have at least one Table B item and a max of 5 Table B items.

Specify max_num in your Inline definition to limit the number.
extra specifies how many blank inlines to show.
Is the 1 inline required? As in you want to trigger a validation error if table B isn't filled with at least 1 row?
