By example : {{{ class Order(models.Model): ... support = models.ForeignKey(Support) parutions = models.ManyToManyField(Parution, through='OrderParution', related_name='order') class OrderAdmin(admin.ModelAdmin): ... list_filter = ('support', 'agency', 'parutions') parutions_filter_related_only=True support_filter_related_only=True }}} ",New feature,closed,contrib.admin,dev,Normal,fixed,"admin, list_filter, limit_choices_to",,Accepted,1,0,0,0,0,0
