Form validator classes for ModelForms
ModelForm FormValidator
FormValidator simplifies common patterns used in ModelForm.clean. For example, if there is a response to field A then there should not a be response to field B and visa-versa.
Declare a form with it’s form_validator class and use FormValidatorMixin:
class MyFormValidator(FormValidator):
def clean(self):
self.required_if(
YES,
field='f1',
field_required='f2')
...
class MyModelForm(FormValidatorMixin, forms.ModelForm):
form_validator_cls = MyFormValidator
class Meta:
model = TestModel
fields = '__all__'
Testing
Test the form_validator without having to instantiate the ModelForm:
def test_my_form_validator(self):
options = {
'f1': YES,
'f2': None}
form_validator = MyFormValidator(cleaned_data=options)
self.assertRaises(ValidationError, form_validator.validate)
self.assertIn('f2', form_validator._errors)
