Validation in django?

Question

Django

Good afternoon!
how to create a validation for one input field, you need to make sure that it is either a phone of the form +7 xxx xxx xx xx, or a date in the format DD.MM.YYYY or YYYY-MM-DD, or an email?

Answer 1

The only thing that comes to mind is to override the check method, and in it check through or,
a regular expression match.
