What is the difference between Django Serializer and ModelSerializer?

What is the difference between Django Serializer and ModelSerializer?

Django Serializer is a base class for serializing data, while ModelSerializer is a shortcut that automatically creates fields based on a model.

Can you give me an example of when to use each?

Use Serializer when you need custom validation or fields not directly tied to a model. Use ModelSerializer for straightforward model serialization.

Are there any performance differences between the two?

ModelSerializer can be more efficient since it automatically generates fields, reducing boilerplate code. However, Serializer offers more flexibility.

What about nested serializers?

Both serializers can handle nested data, but ModelSerializer simplifies the process by automatically handling related fields.
