What are some examples of Django validators?

Django provides several built-in validators. For example, you can use MaxLengthValidator to limit the length of a field.

Can you give me a code example of using MaxLengthValidator?

Sure! Here's a simple example:

from django.core.validators import MaxLengthValidator
from django.db import models

class MyModel(models.Model):
    my_field = models.CharField(max_length=100, validators=[MaxLengthValidator(50)])

This will ensure that my_field cannot exceed 50 characters.

What other validators are available in Django?

Django has many validators like EmailValidator, URLValidator, and RegexValidator. Each serves a specific purpose.

How do I create a custom validator in Django?

To create a custom validator, define a function that raises a ValidationError if the value is invalid. Then, use it in your model.
