Django admin field choices render as multiple checkbox -

-

i'm trying customise django admin page. want single model field render choices passed checkboxselectmultiple, can't work.

here relevant part of models.py:

from django.db import models django.contrib.auth.models import user django.contrib import admin  class event(models.model):     group_owner_choices = (             ('vcoe', "vcoe"),             ('cssi', 'cssi'),             ('essc', "essc"),             ('tmscc', "tmscc"),             ('inmc', "inmc"),             ('ccs7', "ccs7"),             ('ias', "ias"),         )      group_owner = models.booleanfield(choices=group_owner_choices, blank=true, default=false)

i can't use django formfield_overrides(https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.modeladmin.form) because have more 1 booleanfield , keep other booleanfield's intact.

here found other questions

from django.contrib import admin .models import event django import forms  class eventgroupowneradminform(forms.modelform):     def __init__(self, *args, **kwargs):         super(eventgroupowneradminform, self).__init__(*args,**kwargs)         self.fields["group_owner"].widget = forms.widgets.checkboxselectmultiple()  class eventadmin(admin.modeladmin):     form = eventgroupowneradminform  admin.site.register(event , eventadmin)

but field doesnt render anything. help?
