Django：覆盖 UserCreationForm 上的 form.errors 消息

Question

I'm trying to override (add languages) the messages of form.errors. I've tried this:

forms.py

class CreateUserForm(UserCreationForm):
    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']


    def __init__(self, *args, **kwargs):
        super(CreateUserForm, self).__init__(*args, **kwargs)
        self.error_messages['duplicate_username'] = 'some message'

After the form is submitted, it's not saved because username are unique and the error is displayed on the template. I'd like to make the same with the password but I can't find out the errors' key for each password validation. Can you provide me it?

Answer 1

set error_messages --(Django doc) attribute in Meta class as,

class CreateUserForm(UserCreationForm):
    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']

If you want to override the password mismatch error message, override the error_messages attribute in the form class (not in the Meta class) as below,

class CreateUserForm(UserCreationForm):
    
    # other code
