How to change the field name of Serialzed User Model on frontend in Django Rest Framework?-CodePudding

I am making a simple Login/Logout App using REST API in Django DRF. I am using the default User model for this behavior.

In the Login API, I wanted to authenticate the user with email, hence I wrote the custom authentication using ModelBackend. Everything works fine.

But, I want to change the word username to email in the front of the Login API. I tried using the source attribute, but it does not change. Is there any easy way to do it? I am looking for something like verbose_name, that is used in Django Models.

My serializers.py is:

class LoginSerializer(serializers.Serializer):
    username = serializers.CharField(source='Email')
    password = serializers.CharField()

    def validate(self, data):
        user = authenticate(**data)
        if user and user.is_active:
            return user
        raise serializers.ValidationError('Incorrect Credentials Passed.')

Again, I am using the default User Model, and I don't want to overwrite/override/extend the User Model. I just want to change the name of the field username on the frontend to be shown as email.

Any help will surely be appreciated.

You need to pass a value called email and not username to your ModelBackend subclass:

class LoginSerializer(serializers.Serializer):
    username = serializers.CharField()
    password = serializers.CharField()

    def validate(self, data):
        user = authenticate(**{'email': data['username'], 'password': data['password']})
        if user and user.is_active:
            return user
        raise serializers.ValidationError('Incorrect Credentials Passed.')
