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):

For simple cases, you can specify custom error messages

class AuthorForm(forms.ModelForm):
    first_name = forms.CharField(error_messages={'required': 'Please let us know what to call you!'})
    class Meta:
        model = Author
