Here password is in the form of text ,i want encrypted form of password.here one to one relation is there between user and userprofile table.i want to create user and userprofile data by only one method, that's why i need to encrypt password also at the same time only.

I got the answer.
class UserProfileSerializer(serializers.ModelSerializer):
user = UserSerializer(required=True)
class Meta:
model = UserProfile
fields = ('user', 'contact_no', 'role',)
def create(self, validated_data):
"""
Overriding the default create method of the Model serializer.
:param validated_data: data containing all the details of profile
:return: returns a successfully created profile record
"""
user_data = validated_data.pop('user')
user = UserSerializer.create(UserSerializer(),validated_data=user_data)
user.set_password(user.password)
user.save()
profile, created = UserProfile.objects.update_or_create(user=user, contact_no=validated_data.pop('contact_no'),
role=validated_data.pop('role'))
return profile
we need to add only two lines to get the encrypted password here.
user.set_password(user.password)
user.save()
