What is the serializer equivalent of the clean method for django forms.
My use case is that I want to do custom model field validation of some fields for a model serializer class. My guess is it could be the run_validators, for the framework. But I am not sure with certainty.
Thanks, Best regards,

Serializers in Django REST Framework are responsible for converting objects into data types understandable by javascript and front-end frameworks. Serializers also provide deserialization, allowing parsed data to be converted back into complex types, after first validating the incoming data.
The . is_valid() method takes an optional raise_exception flag that will cause it to raise a serializers. ValidationError exception if there are validation errors.
In function based views we can pass extra context to serializer with "context" parameter with a dictionary. To access the extra context data inside the serializer we can simply access it with "self. context". From example, to get "exclude_email_list" we just used code 'exclude_email_list = self.
The ModelSerializer class is the same as a regular Serializer class, except that: It will automatically generate a set of fields for you, based on the model. It will automatically generate validators for the serializer, such as unique_together validators. It includes simple default implementations of .

The serializers in REST framework work very similarly to Django's Form and ModelForm classes. We provide a Serializer class which gives you a powerful, generic way to control the output of your responses, as well as a ModelSerializer class which provides a useful shortcut for creating serializers that deal with model instances and querysets.
The django-rest-framework-serializer-extensions package provides a collection of tools to DRY up your serializers, by allowing fields to be defined on a per-view/request basis. Fields can be whitelisted, blacklisted and child serializers can be optionally expanded.
.is_valid () - Deserializes and validates incoming data. .validated_data - Returns the validated incoming data. .errors - Returns any errors during validation. .save () - Persists the validated data into an object instance. There are four methods that can be overridden, depending on what functionality you want the serializer class to support:
Well, just gone through the documentation and the equivalent is validate (for object level validation). For field level validation use. validate_<field_name>'
