Exclude username or password from UserChangeForm in Django Auth -

i'm trying figure out way on how exclude username and/or password userchangeform. tried both exclude , fields doesn't work these 2 fields.

here's code:

class artistform(modelform):     class meta:         model = artist         exclude = ('user',)  class userform(userchangeform):     class meta:         model = user         fields = (             'first_name',             'last_name',             'email',             )         exclude = ('username','password',)      def __init__(self, *args, **kwargs):         self.helper = formhelper         self.helper.form_tag = false         super(userform, self).__init__(*args, **kwargs)         artist_kwargs = kwargs.copy()         if kwargs.has_key('instance'):             self.artist = kwargs['instance'].artist             artist_kwargs['instance'] = self.artist         self.artist_form = artistform(*args, **artist_kwargs)         self.fields.update(self.artist_form.fields)         self.initial.update(self.artist_form.initial)      def clean(self):         cleaned_data = super(userform, self).clean()         self.errors.update(self.artist_form.errors)         return cleaned_data      def save(self, commit=true):         self.artist_form.save(commit)         return super(userform, self).save(commit) 

you won't able if use userchangeform.

see https://github.com/django/django/blob/master/django/contrib/auth/forms.py.

you notice userchangeform on page explicitly defines username , password. these fields present in variable declared_fields on form.

exclude , fields work on fields taken model defined in meta. if explicitly define field i.e declared_fields, present on form if have been excluded using exclude. so, these fields show you.

to read more on check __new__ of modelformmetaclass @ https://github.com/django/django/blob/master/django/forms/models.py

workaround:

do not use userchangeform , read code. doesn't provide much. can write own form extends modelform , set meta model user. copy parts userchangeform in form.

class userform(forms.modelform):      class meta:         model = user      def __init__(self, *args, **kwargs):         #copy functionality want form userchangeform      def clean_password(self):         #copy functionality provided userchangeform
