Creating Django Rest Framework's Profile API

Updated: Dec 3, 2022


1. Create profile API
  • Handles registration of new users

  • Validate profile Data

2. Listing Existing Profiles.
  • Search for profile and name

  • Email and Name

  • List all profile when HTTP GET method is called.

  • Create new Profile when HTTP POST method is called.


from rest_framework import serializers

from profiles_api import models

class HelloSerializers(serializers.Serializer):


age = serializers.IntegerField()

class UserProfileSerializer(serializers.ModelSerializer):

"""Serialize a user profile object """

""" Note: Define a meta class , the way you work with ModelSerializer is to use a meta class to configure a serializer to point to a specific model in our project. Class Meta will point to UserProfile models . Here need to specify list of fields in our model that has to manage through serializer """

class Meta:

model = models.UserProfile

fields = ('id', 'email','name', 'password')

extra_kwargs = {

'password' : { 'write_only' : True, 'style' :{'input_type' :'password'}}


"""Now override the create function of DRF so as to save password in hash type not in simple readable format"""

"""Whenever we create a profile object with our serializer. It will validate the object and

fields, provided to serializer and then it will call the create function and passing it in validated_data"""

def create(self, validated_data):

"""create and return new user"""

user = models.UserProfile.objects.create_user(





return user

"""Note: it will override the create function and call our create_user function from file."""

def update(self, instance, validated_data):

"""Handle update user account """

if 'password' in validated_data:



return super().update(instance, validated_data)

"""The default update logic for DRF ModelSerializer will take whatever fields are

provided(in our case name, email and password) and pass them directly to the model.

This is fine with the fields like name and email, However the password field require some additional logic

to hash the pasword before saving the update. Now password will be save in hash or non readable form.

Therefore we override the update() method to add this logic to check the presence of password in validated_data

which is passed from DRF when updating an object.

If the fields exists we will pop the password from the validated_data dictionary and set it using set_password

which is save the password in Hash type.

Once that done we use super().update() to pass the values to the existing DRF update method,

to handle the remaining fields"""

Note: Now you can delete, update and path anyones account try it before going forward you will see all the option to edit and delete. However to control this and only authentic user can modify or delete its own profile we have to add authentications and permissions for that create a new file in profiles_api

and write down the following code.

from rest_framework import permissions

class UpdateOwnProfile(permissions.BasePermission):

"""Allow user o edit their own permission"""

def has_object_permission(self, request, view, obj):

"""check user is trying to update their own profile"""

if request.method in permissions.SAFE_METHODS:

return True


"""if request.method contain GET request it will show all the profiles

means readable mode. if request.method contain editable request like PUT,PATCH,DELETE etc then it will check === if both are same it will return true else false means not allow to perform put, PATCH kind of operation. you will not see the option their."""
