Django: Overriding ModelAdminForm's field attributes

I am trying to override a ModelAdmin's form field as below:

class MyModelAdmin(admin.ModelAdmin):
    def ge开发者_运维百科t_form(self, *args, **kwargs):
        form = super(MyModelAdmin, self).get_form(*args, **kwargs)
        form.fields['password'].help_text = "..."
        return form

I am getting an Attribute error: "type object 'FailedLoginForm' has no attribute 'fields'".

Isn't ModelAdmin.get_form() returning a regular Django form object. How come it doesn't have fields?

I suggest that you simply override the form that you want.

class UserCreationForm(UserCreationForm):   
    # we want to use the email as the username
    def __init__(self, *args, **kwargs):
        super(UserCreationForm, self).__init__(*args, **kwargs)
        # let's require these fields
        self.fields['email'].required = True
        self.fields['first_name'].required = True
        self.fields['last_name'].required = True
        # let's not require these
        self.fields['username'].required = False
        self.fields['password1'].required = False
        self.fields['password2'].required = False

From there you can do pretty much anything you want.
