What are serializer fields in Django?

Serializer fields in Django are used to define how model instances are converted to and from JSON or other content types.

Can you give me an example of how to use them?

Sure! You can define serializer fields in a serializer class like this:

from rest_framework import serializers

class MyModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = ['id', 'name', 'description']

What types of fields can I use in serializers?

You can use various field types like CharField, IntegerField, DateTimeField, and more, depending on your model's attributes.

How do I validate data in serializer fields?

You can add validation by overriding the validate_<field_name> method in your serializer class to implement custom validation logic.
