Python Validator function for phone and email-CodePudding

I have a website to validate spreadsheet headers and rows when a spreadsheet is uploaded to the site,here i have some validation function where i will have to validate the rows according the attributes of the field in my case i have model like below:

models.py

from phone_field.models import PhoneField

class Address(BaseModel):
phone = PhoneField(max_length=255, blank=True)
address_1 = models.CharField(max_length=255)
address_2 = models.CharField(max_length=255, blank=True)
city = models.CharField(max_length=255, blank=True)
email = models.EmailField(unique=True, blank=True, null=True)

You can see the Django document about the validators

https://docs.djangoproject.com/en/4.0/ref/validators/

also, you can use this one

def validate_email(value):
    query = model.objects.all().values('field__email')
    try:
        if value not in query:
            return True
    except ValidationError:
        return False
