title: Whether I can write the logic in View?
body: <p>I can write myself's logic in the Serializer's create method:</p>
  
  <pre><code>class UserCreateSerializer(ModelSerializer):
      class meta:
          model = User
          fields = "__all__"
  
      def create(self, validated_data):
          username = validated_data["usernmae"]
          email = validated_data["email"]
          password = validated_data["password"]
  
          # there I can do myself's logic
  
          return validated_data
  </code></pre>
  
  <p>Whether I can write the logic in View? If is, how to do with that in View? </p>
