Show a ManyToManyField as Checkboxes in Django Admin

Question

Is there a simple way to show a ManyToManyField as Checkboxes in Django Admin? Thanks in advance!

Answer 1

This is most certainly possible. Here is the code which you can place in the ModelAdmin subclass:

def formfield_for_manytomany(self, db_field, request=None, **kwargs):
    if db_field.name == 'your field name':
        kwargs['widget'] = form_widgets.CheckboxSelectMultiple()
        kwargs['help_text'] = ''

    return db_field.formfield(**kwargs)

This was derived from looking into the admin code.
