Validating form data with Django REST framework

“

- [Instructor] Right now, the validation is simple, whether or not a form is filled out. Let's do something a bit more useful. Let's check for a specific street address format. In the booking serializer, we're going to add a street address error message. In a Django REST framework serializer, you only have to prefix the field name with validate in order to implement custom validation for the field. We can define a regular expression that we want to match, which will be a number followed by a street name and any other suffix and if the street address that's filled out matches, we simply return that value. Otherwise, we raise a validation error.
