django-loginas
About
"Login as user" for the Django admin.
loginas
supports Python 3 only, as of version 0.4. If you're on 2, use
0.3.6.
Installing django-loginas
-
Add loginas
to your Python path, or install using pip: pip install django-loginas
-
Add the loginas
app to your INSTALLED_APPS
:
INSTALLED_APPS = [... 'loginas', ...]
- Add the
loginas
URL to your urls.py
:
urlpatterns = [
path('admin/', include('loginas.urls')),
path('admin/', admin.site.urls),
]
- If you're using a custom User model, you'll need to add the template to it so the button shows up:
class YourUserAdmin(ModelAdmin):
change_form_template = 'loginas/change_form.html'
At this point, you should be good to go. Just visit the Django admin, navigate to a user and you should see the "Log
in as user" button at the top right of the screen.
Configuring
At this point, the only users who will be able to log in as other users are those with the is_superuser
permission.
If you use custom User models, and haven't specified that permission, or if you want to change which users are
authorized to log in as others, you can define the CAN_LOGIN_AS
setting, like so:
CAN_LOGIN_AS = lambda request, target_user: request.user.is_superuser
CAN_LOGIN_AS = lambda request, target_user: request.user.is_superuser and not target_user.is_superuser
CAN_LOGIN_AS = "utils.helpers.custom_loginas"
By default, clicking "Login as user" will send the user to settings.LOGIN_REDIRECT_URL
.
You can override this behavior like so:
LOGINAS_REDIRECT_URL = '/loginas-redirect-url'
In order to automatically restore the original user upon log out, replace the default log out
with a special log out that restores the original login session from a signed session.
from django.core.urlresolvers import reverse_lazy
LOGOUT_URL = reverse_lazy('loginas-logout')
Additionally, you can specify the redirect url for logout (the default is settings.LOGIN_REDIRECT_URL
).
from django.core.urlresolvers import reverse_lazy
LOGINAS_LOGOUT_REDIRECT_URL = reverse_lazy('admin:index')
By default, clicking "Login as user" will not update user.last_login
.
You can override this behavior like so:
LOGINAS_UPDATE_LAST_LOGIN = True
By default, the login switch message will generate Django admin LogEntry
messages using the User
model's
USERNAME_FIELD
like f"User {impersonator_user.getattr(USERNAME_FIELD)} logged in as {impersonated_user.getattr(USERNAME_FIELD)}."
You can override this behavior by passing in a different
field name:
LOGINAS_USERNAME_FIELD = 'email'
Other implementation suggestions
Existing logout view?
If you already have a logout view, you can modify to login the original user again after having had a "login as" session. Here's an example:
class LogoutView(LogoutView):
template_name = 'myapp/logged_out.html'
@method_decorator(never_cache)
def dispatch(self, request, *args, **kwargs):
from loginas.utils import restore_original_login
restore_original_login(request)
return redirect('myapp:login')
Template awareness
You can add the context processor loginas.context_processors.impersonated_session_status
in your settings.py file if you'd like to be able to access a variable is_impersonated_session
in all your template contexts:
TEMPLATES = [
{
...
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
...
'loginas.context_processors.impersonated_session_status',
],
},
},
]
Note that django-loginas won't let you log in as other superusers, to prevent
privilege escalation from staff users to superusers. If you want to log in as
a superuser, first demote them to a non-superuser, and then log in.
