When I use Django EmailField with null=True, blank=True, unique=True, admin saves empty string (“”) instead of null. So I recieve “User with this Email address already exists.” error.
As this ticket says this problem must be solved and it’s OK when I use CharField but not EmailField. Is there any way to solve this?
you can add a clean method for this, ie if value for email is ” then with clean method, you can add custom value to email and save it in db.
you can do this as
class Mymodel(models.Model):
email = models.EmailField(null=True, blank=True, unique=True)
def clean(self):
if self.email == '':
self.email=None
super().clean()

To resolve this issue, you need to convert empty strings to None before saving the data to the database. One way to do this is by overriding the save() method in your model.
from django.db import models
class MyUser(models.Model):
email = models.EmailField(null=True, blank=True, unique=True)
def save(self, *args, **kwargs):
# Convert empty string to None for the email field
if self.email == '':
self.email = None
super(MyUser, self).save(*args, **kwargs)
I hope this will help you a little.
