plain.impersonate
See what your users see.
A key feature for providing customer support is to be able to view the site through their account.
With impersonate installed, you can impersonate a user by finding them in the Django admin and clicking the "Impersonate" button.
Then with the admin toolbar enabled, you'll get a notice of the impersonation and a button to exit:
Installation
To impersonate users, you need the app, middleware, and URLs:
# settings.py
INSTALLED_PACKAGES = INSTALLED_PACKAGES + [
"plain.admin.impersonate",
]
MIDDLEWARE = MIDDLEWARE + [
"plain.admin.impersonate.ImpersonateMiddleware",
]
# urls.py
urlpatterns = [
# ...
path("impersonate/", include("plain.admin.impersonate.urls")),
]
Settings
By default, all admin users can impersonate other users.
# settings.py
IMPERSONATE_ALLOWED = lambda user: user.is_admin
