(Django) How do I make this signup model and signupview?

Question

I have been trying to emulate Instagram signup which takes either one of 'phone' or 'email'. The image attached shows what requirements are

Below are the files for my 'account' Django app that I created:

models.py

from django.db                      import models

class Account(models.Model):
    email       = models.EmailField(max_length = 254)
    password    = models.CharField(max_length=700)
    fullname    = models.CharField(max_length=200)
    username    = models.CharField(max_length=200)
    phone       = models.CharField(max_length=100)
    created_at  = models.DateTimeField(auto_now_add=True)
    updated_at  = models.DateTimeField(auto_now=True)

    class Meta:
        db_table = 'accounts'

    def __str__(self):
        return self.username + " " + self.fullname

views.py

import json
import bcrypt
import jwt

from django.views       import View
from django.http        import HttpResponse, JsonResponse
from django.db.models   import Q

from .models    import Account

class SignUpView(View):
    def post(self, request):
        data = json.loads(request.body)
        try:
            if Account.objects.filter(email=data['email']).exists():
                return JsonResponse({"message": "ALREADY EXIST"}, status=409)
            elif Account.objects.filter(email=data['phone']).exists():
                return JsonResponse({"message": "ALREADY EXIST"}, status=409)
            elif Account.objects.filter(username=data['username']).exists():
                return JsonResponse({"message": "ALREADY EXIST"}, status=409)

            hashed_pw = bcrypt.hashpw(data['password'].encode('utf-8'),bcrypt.gensalt()).decode()
            Account.objects.create(
                    email       = data['email'],
                    password    = hashed_pw,
                    fullname    = data['fullname'],
                    username    = data['username'],
                    phone       = data['phone'],

            )
            return JsonResponse({"message": "SUCCESS"}, status=200)

        except KeyError:
            return JsonResponse({"message": "INVALID_KEYS"}, status=400)

Since the user put in either phone number or email, how do I make django to distinguish between the phone and email and put it in the correct model?

Answer 1

You can use validate_email to validate input is email or not at first, if not then try to validate phone style.

from django.core.validators import validate_email

try:
    validate_email(data['email_or_phone'])
    print('input is email')
except ValidationError:
    print('do phone validate')
