What are Django model forms and their built-in validators?

What are Django model forms and how do built-in validators work?

Django model forms are a way to create forms based on your models. Built-in validators help ensure that the data entered meets certain criteria.

Can you give me examples of some built-in validators?

Sure! Some built-in validators include MaxLengthValidator, MinValueValidator, and EmailValidator. They help enforce rules on the data.

How do I use these validators in my model form?

You can use them by adding them to the field definitions in your model. For example, name = models.CharField(max_length=100, validators=[MaxLengthValidator(50)]).

What happens if the validation fails?

If validation fails, Django will raise a validation error, and the form will not be submitted until the issues are resolved.
