django-username-email's Issues

email unique error should be translatable

AbstractCUser has an EmailField. The error message "unique" is not translatable.

Form validation error on email field

When validating the email address I kept running into errors when a new user wants to sign up.

I see this errors, because I use this print statement:
print(form.errors.as_json())

When I leave email empty I get this error (which is expected):
{"email": [{"message": "This field is required.", "code": "required"}]}

When I enter a invalid email address I get this error (which is expected):
{"email": [{"message": "Enter a valid email address.", "code": "invalid"}]}

When I enter a valid email address I get this error (which is NOT expected):
{"email": [{"message": "This field cannot be blank.", "code": "blank"}]}

To fix this issue I edited the AbstractCUser class in cuser.models.py
I added blank=True, like this:

email = models.EmailField(
    _('email address'),
    blank=True,
    unique=True,
    error_messages={
        'unique': _("A user with that email address already exists."),
    },
)

Maybe I made a mistake somewhere else, not sure.
But this was my solution.

django.utils.translation.ugettext_lazy() is deprecated

Currently I'm getting a lot of warnings. The log is below. Simply changing all occurances of ugettext_lazy to gettext_lazy should do the trick.

django v4 complains about a missing "cuser" migration

django v4 complains about a missing "cuser" migration
manage.py makemigrations creates the following "" migration.
I suspect that this migration must be added to cuser source code for django v4 compatibility

What is required to get a new release on pipi?

Not having this change 8246395 is causing grief with my deployments as Django wants to fix it by creating a new migration.

Missing migration

Hi, migrate command says that I have missing migration:

Your models have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

When I ran the command ./manage.py makemigrations cuser it generated the new migration file for me with

migrations.AlterField(
            model_name='cuser',
            name='email',
            field=models.EmailField(error_messages={'unique': 'A user with that email address already exists.'}, max_length=254, unique=True, verbose_name='email address'),
        ),

This looks odd because we have the same email field parameters in initial migration. Maybe it is due to that I use SQLite database for my small project. Anyway, I gonna to make PR with this odd missing migration.

Does anybody observe the same issue?

AttributeError: type object 'UserAdmin' has no attribute '_meta'

I want to extend the CUser model with custom properties and still have the admin interface working. Currently, I'm getting the above error with the following code.

# models.py

from cuser.models import AbstractCUser

class User(AbstractCUser):
    pass

# admin.py

from cuser.admin import UserAdmin
from .models import *

admin.site.register([User, UserAdmin])

Faulty `invalid_login` error message

The error message in cuser/templates/forms.py

'invalid_login': _(
            "Please enter a correct %(username)s and password. Note that both "
            "fields may be case-sensitive."
        ),

translates to :

Please enter a correct email address and password. Note that both fields may be case-sensitive.

This is incorrect because email addresses are not case-sensitive. Only the password field may be case-sensitive.

Avoid creating cuser_cuser_* tables when extend AbstractCUser.

I created a custom User model based on your django-username-email AbstractCUser class. A side effect is the creation of cuser_cuser_* tables even though they are never populated. I’m wondering how to avoid creating these tables.

Here is the contents of my users/model.py:
from django.db import models
from django.contrib.auth.models import Group as BaseGroup
from cuser.models import AbstractCUser, CUserManager

class User(AbstractCUser):
    """
    Password and email are required. Other fields are optional.
    """
    class Meta(AbstractCUser.Meta):
        swappable = 'AUTH_USER_MODEL'

class UserManager(CUserManager):
    pass

class Group(BaseGroup):
    class Meta:
        proxy = True

Help with CUser: Reverse accessor clashing

I am using cuser as follows (having imported AbstractCUser):
class Utilisateur(AbstractCUser):
telephone = models.CharField(max_length=10)
doit_changer_mot_de_passe = models.BooleanField(default=True)
a_accepte_CGU = models.BooleanField(default=False)
est_administrateur = models.BooleanField(default=False)

Django returns the following errors:
core.Utilisateur.groups: (fields.E304) Reverse accessor for 'Utilisateur.groups' clashes with reverse accessor for 'CUser.groups'.
HINT: Add or change a related_name argument to the definition for 'Utilisateur.groups' or 'CUser.groups'.

HINT: Add or change a related_name argument to the definition for 'CUser.user_permissions' or 'Utilisateur.user_permissions'.

What would you advise?

no such table: 'cuser_user'

Anytime I try to login a user, create a super user, or even entering admin I get this error, I tried running python manage.py migrate --run-syncdb with no changes.

Exception Type: OperationalError at /admin/login/
Exception Value: no such table: cuser_cuser

Manager isn't available; 'cuser.CUser' has been swapped for 'myapp.User'

When trying to bring my own user model as an extension to CUser, I'm getting the above error message when trying to sign up.

from cuser.models import AbstractCUser

class User(AbstractCUser):
    pass

Using cuser with an started project

When a project has data, the migration process raises a:
django.db.migrations.exceptions.InconsistentMigrationHistory: Migration wagtaildocs.0001_initial is applied before its dependency cuser.0001_initial on database 'default'.
I'm reading that django docs don't recommend to change the user model once started the project. Should it be possible with django-username-email?

Migrations for Django 2.2 fail

Hi,

I just tried upgrading my development environment (using django-username-email 2.2.2) to Django 2.2, and when I ran migrate, I got this:

django.db.utils.IntegrityError: duplicate key value violates unique constraint "auth_permission_content_type_id_codename_01ab375a_uniq"
DETAIL:  Key (content_type_id, codename)=(6, add_group) already exists.

In this case, the old content type being moved from was auth, and the new one was cuser. Looking in my database, I appear to have the following:

>>> from django.contrib.auth.models import Permission
>>> foo = list(Permission.objects.all())
>>> foo = [obj for obj in foo if obj.codename == 'add_group']
>>> foo
[<Permission: auth | group | Can add group>, <Permission: cuser | group | Can add group>]

Any ideas of how to fix this? I think I could probably fix by removing all the Permission objects with content type cuser right before the upgrade, but curious if you have better ideas, of if there's a way to fix this in django-username-email itself.

Referring to wrong step before under Install & Set up

In the text it says

but with the following adjustments: After step 2, follow these instructions, but instead of using [...]. Then for step 3 of the steps below, you should set AUTH_USER_MODEL to your custom user model instead of CUser’s CUser model

Since the "Step 3" part seems to be referring to Step 4 and step 3 really is to add the app to the installed apps, it seems as if you meant to say "step 4" here.
