Max_length of EmailField in django.contrib.auth.models.User

[somen...@gmail.com]

Hi,

The User class in https://docs.djangoproject.com/en/1.7/ref/contrib/auth/#django.contrib.auth.models.User is using EmailField with 254 max_length? I want to follow RFC (See https://docs.djangoproject.com/en/1.7/ref/models/fields/#emailfield)

Thanks,

[Anderson Resende]

No, the user class uses 75. You need to change to 254.

models.EmailField(max_lenght=254)

Thanks, Anderson, but can I overwrite the length of User class? How? Sorry I'm still a newbee? With AbstractUser? [https://docs.djangoproject.com/en/1.7/topics/auth/customizing/#django.contrib.auth.models.CustomUser] or Extending user class [https://docs.djangoproject.com/en/1.7/topics/auth/customizing/#extending-the-existing-user-model]?

On the other, hand, it were useful if someone could add the information in the web page.

Currently you need to use a custom user model if you want to change the username max_length. There's an open ticket to increase the default length to 254 though: https://code.djangoproject.com/ticket/20846

Hi

I have been using this patch to get around the short user name (which is 30 characters):

#--------------------------------------------------------------------------
#
# Patch to allow username to exceed the default maximum of 30 characters
#
# http://stackoverflow.com/a/6453368/1228131
#
# Note: this works for django 1.3, 1.4, 1.5, 1.6
#

# Import what we need
from django.contrib.auth.models import User
from django.core.validators import MaxLengthValidator

# New username length
NEW_USERNAME_MAX_LENGTH = 75

# Method to patch the user name maximum length
def monkey_patch_username_maximum_length():

username = User._meta.get_field("username")
username.max_length = NEW_USERNAME_MAX_LENGTH

for validator in username.validators:
if isinstance(validator, MaxLengthValidator):
validator.limit_value = NEW_USERNAME_MAX_LENGTH

# Patch the user name maximum length
monkey_patch_username_maximum_length()

You can inheriant of AbstractBaseUser and define your field:

from django.contrib.auth.models import AbstractBaseUser

class MyCustomUser(AbstractBaseUser):
     mail = models.EmailField(max_lenght=254)

    REQUIRED_FIELDS = ['mail']
     # more code
 

Please sorry about my english, I'm a Brazilian guy rsrsrs

I will give you one more complete example:
Custom a User is not easy you need to do many things:

In that link django-docs explain all for you and there is an example with email field.

https://docs.djangoproject.com/en/1.7/topics/auth/customizing/#a-full-example


My tip is: In the docs there is many other fields like birth_date that you can remove.
Second, In docs the email field has used with username, you can create your own username field and in

USERNAME_FIELD = 'email' change for USERNAME_FIELD = 'myusername'
