What are common errors in Django serializer validation?

Common errors include missing required fields, incorrect data types, and validation failures for custom fields.

Can you give examples of how to fix these errors?

Sure! For missing fields, ensure you define them in your serializer. For data types, use the correct field types like IntegerField for integers.

What about custom validation errors?

For custom validation, override the validate method in your serializer to add specific checks and raise serializers.ValidationError.

How can I test my serializers to catch these errors?

You can write unit tests using Django's test framework to validate your serializers with various input scenarios.
