I just know this is a stupid question, but I'm only beginning to figure
this out, so I hope you all will have mercy on me.
I'm trying to establish a many to many relationship and use the
filter_interface to select which items from A are applicable to B. My
problem is that the first of the two boxes has nothing in it. The
heading's there, but no items. Shortened model below:
_______________________________
from django.db import models
STATUS_CHOICES = (
('vintage', 'Vintage'),
('postfender', 'Post-Fender'),
)
YEAR_CHOICES = (
('1950', '1950'),

)
WIDTH_CHOICES = (
('15 1/2', '15½'),
)
DEPTH_CHOICES = (
('2 2/3', '2'),
)
STYLE_CHOICES = (
('Single_Hollow', 'Single Cutaway Hollowbody'),
('Double_Hollow', 'Double Cutaway Hollowbody'),
