User Registeration Using Django Rest Framework - django

Question

I am trying to create a api for user Registration using the django rest framework.
I have the following models.py file
from __future__ import unicode_literals
from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver
class UserProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE , primary_key = True)
mobileNumber = models.IntegerField(default=0)
avatar= models.ImageField(upload_to = 'User/' , default = '/static/User/defaultProfileImage.png')
def create_user_profile(sender, **kwargs):
if kwargs['created']:
profile = UserProfile.objects.create(user=kwargs['instance'])
post_save.connect(create_user_profile, sender=User)
This is my Serializers.py file
from rest_framework import serializers
from User.models import UserProfile
from django.contrib.auth.models import User
class UserSerializer(serializers.HyperlinkedModelSerializer):
username = serializers.CharField()
password1 = serializers.CharField(
style={'input_type': 'password'},
write_only=True)
password2 = serializers.CharField(
style={'input_type': 'password'},
write_only=True)
email = serializers.EmailField()
class Meta:
model = User
fields = (
'id',
'username',
'password1',
'password2',
'email',
'first_name',
'last_name',
)
class UserProfileSerializer(serializers.HyperlinkedModelSerializer):
user = UserSerializer()
class Meta:
model = UserProfile
fields = (
'user',
'mobileNumber',
'avatar')
And following is my views.py file
from User.models import UserProfile
from .serializers import UserProfileSerializer
from rest_framework.viewsets import ModelViewSet
class UserProfileViewSet(ModelViewSet):
queryset = UserProfile.objects.all()
serializer_class = UserProfileSerializer
What is the best way to create a User Registeration using the api view that i have created. I tried many alternatives like overriding the create method in the UserProfile Serializer class and also the drf-writable-nested but got errors.
Please suggest me a way out. Also i want that the api is able to register users when called on by an android app.

You can do this in your Serializers.py file, this should work.
class UserSerializer(serializers.HyperlinkedModelSerializer):
mobileNumber = serializers.IntegerField()
avatar= serializers.ImageField()
class Meta:
model = User
fields = ('username', 'first_name', 'last_name', 'email', 'password', 'mobileNumber', 'avatar')
def create(self, validated_data):
mobile_number = validated_data.pop('mobileNumber', None)
user = super(UserSerializer, self).create(validated_data)
user.set_password(raw_password=validated_data['password'])
user.save()
userprofile = user.userprofile
userprofile.mobileNumber = mobile_number
userprofile.save()
return user
def update(self, instance, validated_data):
mobile_number = validated_data.pop('mobileNumber', None)
userprofile = instance.userprofile
userprofile.mobileNumber = mobile_number
userprofile.save()
return super(UserSerializer, self).update(instance, validated_data)
Chuck the UserProfileSerializer for this use case, i feel here its not really needed.
Your views.py and models.py look cool to me.
Hope this helps you :-)
