How to make a word filter in django?

Question

Django

There is a form for entering mail, name, subject and text. How to make a filter so that the user cannot send text, for example, with a swear word?

Answer 1

Add a clean-method to check the desired field to the form class :

STOP_LIST = [
    'мат',
    'мат',
    'мат',
]

class ContactForm(forms.Form):
    ...

    def clean_text(self):
        text = self.cleaned_data['text']
        for word in STOP_LIST:
            if word in text:
                raise forms.ValidationError("Вы позволили себе немного лишнего! Одумайтесь и исправьте текст!")
        return text
