Create Custom Error Messages with Model Forms

Question

I can see how to add an error message to a field when using forms, but what about model form?

This is my test model:

class Author(models.Model):

I have a cleaner solution, based on jamesmfriedman's answer. This solution is even more DRY, especially if you have lots of fields.

custom_errors = {
    'required': 'Your custom error message'
}

class AuthorForm(forms.ModelForm):
    class Meta:
        model = Author

    def __init__(self, *args, **kwargs):
        super(AuthorForm, self).__init__(*args, **kwargs)

        for field in self.fields:
            self.fields[field].error_messages = custom_errors
