Django Rest Framework update field -

i new drf , trying write custom view / serializer can use update 1 field of user object.

i need make logic update "name" of user.

i wrote serializer:

class clientnameserializer(serializers.modelserializer):     class meta:         model = clientuser         fields = ('name',)      def update(self, instance, validated_data):         instance.name = validated_data.get('name', instance.name)         instance.save()         return instance 

this method never called. tried setting breakpoint there , debug it, never called, if use put, post or patch methods. if add create method being called when use post.

this how view looks like:

class updatename(generics.createapiview):     queryset = clientuser.objects.all()     serializer_class = clientnameserializer     permission_classes = (permissions.isauthenticated,) 

does have suggestion? thanks!

my models.py looks this

class clientuser(models.model):     owner = models.onetoonefield(user,unique=true,primary_key=true)      phone_number = models.charfield(validators=[phone_regex],max_length=20,unique=true)      name = models.charfield(max_length=100,blank=true)     status = models.integerfield(default=1)     member_from = models.datetimefield('member from',auto_now_add=true)     is_member = models.booleanfield(default=false) 

the definition of methods endpoint can accept done in view, not in serializer.

the update method have under serializer needs moved view you'll have like:

# serializers.py class clientnameserializer(serializers.modelserializer):     class meta:         model = clientuser  # views.py class updatename(generics.updateapiview):     queryset = clientuser.objects.all()     serializer_class = clientnameserializer     permission_classes = (permissions.isauthenticated,)      def update(self, request, *args, **kwargs):         instance = self.get_object()         instance.name = request.data.get("name")         instance.save()          serializer = self.get_serializer(instance)         serializer.is_valid(raise_exception=true)         self.perform_update(serializer)          return response(serializer.data) 

take note you're overriding updatemodelmixin , might need change above code little bit right.
