I'm using Django 1.9, and EmailValidator seems to be validating trailing dots in email ids.
faulty_email = '[email protected].'
user.email = faulty_email
user.save()
The above piece of code runs smoothly even though email is an EmailField, which has EmailValidator. The weird thing is, when I run the validation manually, it throws a ValidationError.
In [1]: from django.core.validators import validate_email
In [2]: faulty_email = '[email protected].'
In [3]: validate_email(faulty_email)
---------------------------------------------------------------------------

Does anyone know what the issue is?
When you save() a model you’re only telling Django to commit the object to the database. It doesn’t validate during save. It will throw database exceptions if the fields don’t have the format expected by the database but an EmailField is just a charfield in your db. You should always validate your models before saving them:
user.email = faulty_email
try:
user.full_clean()
except ValidationError as e:
print(e)
else:
user.save()
When using a ModelForm you first validate the form (check form.is_valid()) then save it.
