Question

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

Answer 1

To override for a single field the following is useful:

def get_form(self, request, obj=None, **kwargs):
    form = super(VNodeAdmin, self).get_form(request, obj, **kwargs)
    form.base_fields['node_type'].widget = forms.CheckboxSelectMultiple()
    return form
