Call django Model.full_clean(exclude=None, validate_unique=True) when invoke serializer.is_valid() of ModelSerializer

Django Rest Framework 3 Design

https://www.django-rest-framework.org/community/3.0-announcement/#differences-between-modelserializer-validation-and-modelform

Differences between ModelSerializer validation and ModelForm.

This change also means that we no longer use the .full_clean() method on model instances, but instead perform all validation explicitly on the serializer. This gives a cleaner separation, and ensures > that there's no automatic validation behavior on ModelSerializer classes that can't also be easily replicated on regular Serializer classes.

Warning!

1. One ModelSerializer -> Use this library.
2. Multiple ModelSerializer -> PLEASE READ ME

Installation

pip install drf-fullclean

Configuration

Add the following code into settings.py

DRF_FULL_CLEAN = {
    "DEBUG" : False #set True if you want to see debug print
}

Usage

from drf_fullclean.serializers import FullCleanModelSerializer

class MyModelSerializerClass(FullCleanModelSerializer):
  class Meta:
      model = MyModel
      fields = '__all__

s = MyModelSerializerClass(data=request.POST)
s.is_valid(raise_exception=True)
s.save()

When you call s.is_valid(raise_exception=True) this method invoke also Model.full_clean() method.

The validation FAIL IF Model.full_clean() FAIL.
