django - override password_validation messages -

i use usercreationform create new users.

from django.contrib.auth.forms import usercreationform  class registrationform(usercreationform):       class meta:        model = user        fields = ['username', 'first_name', 'last_name', 'email',  'is_active'] 

usercreationform automatically adds 2 fields (password1 , password2). if password short raises error, telling that. or if simple or common. done via django.contrib.auth.password_validation.

i wonder if can override messages of these errors.

right source code password validation is:

def validate(self, password, user=none):     if len(password) < self.min_length:         raise validationerror(             ungettext(                 "this password short. must contain @ least %(min_length)d character.",                 "this password short. must contain @ least %(min_length)d characters.",                 self.min_length             ),             code='password_too_short',             params={'min_length': self.min_length},         ) 

but when try use code in form definition override error message label changes, error_messages remain same:

password1 = forms.charfield(label='new label', error_messages={'password_too_short': 'my error message short passwords'}) 

what doing wrong?
