django - How to checked permissions in edit user form? -

i have form (thanks alasdair):

class permissionsmodelmultiplechoicefield(forms.modelchoicefield):     def label_from_instance(self, obj):         return "%s" % obj.name   class userform(forms.modelform):     first_name = forms.charfield(label=u'first name', required=true)     last_name = forms.charfield(label=u'last name', required=true)     permissions = permissionsmodelmultiplechoicefield(permission.objects.none(), widget=forms.checkboxselectmultiple)      def __init__( self, *args, **kwargs ):         super( newuserform, self ).__init__( *args, **kwargs )         ctypes = contenttype.objects.filter(             q(app_label='articles') |             q(app_label='tags')         )         self.fields['permissions'].queryset = permission.objects.filter(content_type__in=ctypes)      class meta:         model = user 

and in template permissions shows me permissions this:

[] can change article [] can delete article [] can view article  [...] 

calling form:

profile_user = user.objects.get(pk=user_id)  if request.method == 'post':     form = userform(request.post, instance=profile_user)     if form.is_valid():         form.save()         [... here save permissions ...]         return httpresponseredirect(reverse('home')) else:     form = userform(instance=profile_user) 

how set checked in template permissions assigned edited user?

use argument data populate checkboxes when instantiate form (only outside post request) this:

profile_user = user.objects.get(pk=user_id)  if request.method == 'post':     form = userform(request.post, instance=profile_user)     if form.is_valid():         form.save()         [... here save permissions ...]         return httpresponseredirect(reverse('home')) else:     user_permissions_list = # place here query profile_user permissions     form = userform(instance=profile_user, data={'permissions':user_permissions_list}) 

using data key mark checkboxes according user actual permissions.

hope helps!
