Group Admin

[vinayak11118]

New here. Just wanted to know if there are any group admins present who 
review a post? Because I posted a question sometime back and it still 
hasn't showed up on the news feed.

Django Custom User Admin Login

[vinayak11118]

I'm creating a custom user by extending the AbstractBaseUser class. I have 
read the Django documentation and several tutorials online and I think that 
what I've done till now is very basic and should work.

The problem I'm facing is that even if I create a new DB from scratch and 
do a syncdb, the manage.py console **does not ask me for a admin username 
and password** (as it usually does). Hence, I cannot access /admin. 

The problem is partially (and wrongly) resolved my using 
AUTH_PROFILE_MODULE instead of AUTH_USER_MODEL. This however leads to 
'Users' and 'MyUser' being showed as different objects on the admin page 
i.e. MyUser is not set as the default user. (obviously)

**models.py**

class UserManager(BaseUserManager):
def create_user(self, username, email, corp, password=None):
if not (username or email or corp):
raise ValueError('Users must have an username, email and 
corporation')
user = self.model(username=username, 
email=UserManager.normalize_email(email), corp=corp, )
user.set_password(password)
user.is_active = True
user.save(using=self._db)
return user

def create_superuser(self, username, email, corp, password):
user = self.create_user(self, username, email, corp,
password=password, )
user.is_active = True
user.is_admin = True
user.is_staff = True
user.is_superuser = True
user.save(using=self._db)
return user


class MyUser(AbstractBaseUser, PermissionsMixin):
username = models.CharField(max_length=254, unique=True, 
blank=False)
first_name = models.CharField(max_length=30, blank=True)
last_name = models.CharField(max_length=30, blank=True)
email = models.EmailField(blank=True)
corp = models.ForeignKey(Client, related_name="is_employee_of")

is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
is_staff = models.BooleanField(default=False)

def get_full_name(self):
return self.first_name + " " + self.last_name

def get_short_name(self):
return self.first_name

def __unicode__(self):
return self.username + "@" + self.corp.shortName

objects = UserManager()

USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email', 'corp']


**admin.py**

admin.site.register(Client)
admin.site.register(Address)

class UserCreationForm(forms.ModelForm):
password1 = forms.CharField(label='Password', 
widget=forms.PasswordInput)
password2 = forms.CharField(label='Password Confirmation',

'last_name')

def clean_password2(self):
password1 = self.cleaned_data.get("password1")
password2 = self.cleaned_data.get("password2")

if password1 and password2 and password1 != password2:
raise forms.ValidationError("Passwords don't match")

return password2

def save(self, commit=True):
user = super(UserCreationForm, self).save(commit=False)
user.set_password(self.cleaned_data["password1"])

if commit:
user.save()
return user

class UserChangeForm(forms.ModelForm):
password = ReadOnlyPasswordHashField()

class Meta:
model = MyUser

def clean_password(self):
return self.initial["password"]

class MyUserAdmin(UserAdmin):
form = UserChangeForm
add_form = UserCreationForm

'last_name', 'is_admin', 'is_staff')
list_filter = ('is_admin',)

Re: Django Custom User Admin Login

[vinayak11118]

So I solved the problem. Even I don't know how. :/
I used 
thisas
 a template and added my own models and requirements on top of it. 

Slightly off topic but I needed this setup because I want to grant users 
object level permissions. 
django-guardianlooked like a match 
but I'm having trouble making it work with custom user 
models. The developer of guardian has a 
warningfor
 custom users. 

Since the template I used to create my custom user had 
admin.site.unregister(Group) included in the admin.py file, guardian throws:

'MyUser' has no attribute 'groups' error. Allowing groups to register shows the 
same error. Do we need to implement custom groups when we use custom users? As 
of now, I don't need the group functionality - so it'd be great if there is a 
work around.

Here is my architecture:

|--- *customuser*
   |--- *customauth*
   |--- management
   |--- migrations
   |--- admin.py// same as used in the initial post, slight 
additions
   |--- models.py  // same as used in the initial post, slight additions
   |--- views.py
   |--- *customuser*
   |--- setting.py
   |--- urls.py
   |--- *client001*
   |--- admin.py// posted below
   |--- models.py  // posted below
   |--- views.py  


*So, I have a separate app for each client (customer) that registers for my 
app. Each client can have multiple users with each user having permission 
to 'view' a 'stream' or not. The main app stores a list of all users and 
all clients.*


*customauth/models.py*

class Address(models.Model):
> country = models.CharField(_('Country'), max_length=100, blank=True)
> *** ommited ***
> street_line3 = models.CharField(_('Address Line 3'), max_length=100, 
> blank=True)
>
> class Client(models.Model):
> cID = models.IntegerField(primary_key=True, blank=False)
> *** ommited ***
> address = models.ForeignKey(Address, related_name='located_at')

> def create_user(self, email, username, password=None):

> def create_superuser(self, email, username, password):

Re: Django Custom User Admin Login

[vinayak11118]

Also, from initial tests it appears that django-guardian is not setting 
permissions with custom user. I wrote a small manage.py script to test that:

from django.core.management.base import BaseCommand, CommandError
from iiitd.models import *
from guardian.shortcuts import assign_perm, remove_perm

class Command(BaseCommand):
def handle(self, *args, **options):
user = MyUser.objects.filter(username='abc')[0]
stream = Stream.objects.filter(uuid='001')[0]
assign_perm('read_stream', user, stream)
print user.has_perm('read_stream', stream)
remove_perm('read_stream', user, stream)
print user.has_perm('read_stream', stream)

It prints True in both cases.
However, the guardian_userobjectpermission table is updating correctly when 
I add or delete permissions. Confused. o.O

referencing models before syncdb

[vinayak11118]

I have an actions.py file which defines custom actions for the admin page 
for one of my models. It uses an intermediary page (like the default delete 
action) and hence has a corresponding form which is also declared in the 
same file.

For some reason, I had drop by database (development) and now when I try to 
run syncdb, it gives me the following error:
