Метод django clean не вызывается при валидации формы

Я попробовал самый простой способ валидации формы, который смог найти, используя чистый метод (мне нужно проверить несколько полей). Однако он не работает и не выдает никаких ошибок.

forms.py

class DOEForm1(ModelForm):
class Meta:
    model = Doe
    labels = {
        'column_parameter': ('Parameter to vary'),
        'column_min': ('Minimum value'),
        'column_max': ('Maximum value'),
        'column_step': ('Step value'),
    }
    exclude = ('substrate','row_parameter','row_min','row_max','row_step',)
    def clean(self):
        cleaned_data = super().clean()
        print('test')
        min = cleaned_data.get('column_min')
        max = cleaned_data.get('column_max')
        step = cleaned_data.get('column_step')
        if min and max and step:
            if not (int(step) > 10):
                raise ValidationError(
                '(!) the parameters you inputted dont go well with the substrate size' 
                )
        return cleaned_data

Что я делаю не так?
