django-impersonate ------------------ Simple application to allow superusers to "impersonate" other non-superuser accounts. Dependencies ------------ It was written for Python 2.4+ and Django 1.2.4 but it should work just fine with Django 1.1+ It depends on your project using the django.contrib.session framework. Install ------- PIP: pip install django-impersonate Basic Manual Install: $ python setup.py build $ sudo python setup.py install Alternative Install (Manually): Place impersonate directory in your Python path. Either in your Python installs site-packages directory or set your $PYTHONPATH environment variable to include a directory where the webutils directory lives. Use --- 1) Add 'impersonate' to your INSTALLED_APPS 2) Add 'impersonate.middleware.ImpersonateMiddleware' to your MIDDLEWARE_CLASSES 3) Add 'impersonate.urls' somewhere in your url structure. Example: urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), url(r'^impersonate/', include('impersonate.urls')), ... (all your other urls here) ... ) ** HOW TO USE ** == You can now impersonate another user by hitting the following path: /impersonate/<user-id>/ Replace <user-id> with the user id of the user you want to impersonate. While in impersonation "mode" the request.user object will have an "is_impersonate" attribute set to True. So if you wanted to check in your templates or view, you just do something like... {% if user.is_impersonate %} .... {% endif %} You can reference this URL with reverse() or the {% url %} template tag as 'impersonate-start' == To remove the impersonation, hit the following path: /impersonate/stop/ You can reference this URL with reverse() or the {% url %} template tag as 'impersonate-stop' == To list all users you can go to: /impersonate/list/ This will render the template 'impersonate/list_users.html' and will pass the following in the context: * users - queryset of all users * paginator - Django Paginator instance * page - Current page of objects (from Paginator) * page_number - Current page number, defaults to 1 You can reference this URL with reverse() or the {% url %} template tag as 'impersonate-list' == To search all users you can go to: /impersonate/search/ This will render the template 'impersonate/search_users.html' and will pass the following in the context: * users - queryset of all users * paginator - Django Paginator instance * page - Current page of objects (from Paginator) * page_number - Current page number, defaults to 1 * query - The search query that was entered The view will expect a GET request and look for the 'q' variable being passed. If present, it will search the user entries with the value of 'q'. The fields searched are: User.username, User.first_name, User.last_name, User.email You can reference this URL with reverse() or the {% url %} template tag as 'impersonate-search' == To allow some users to impersonate other users You can optionally allow only some non-superuser and non-staff users to impersonate by adding a IMPERSONATE_CUSTOM_ALLOW setting. Create a function that takes a request object, and based on your rules, returns True if the user is allowed to impersonate or not. == To limit what users a user can impersonate By, optionally, setting the IMPERSONATE_CUSTOM_USER_QUERYSET you can control what users can be impersonated. It takes a request object of the user, and returns a QuerySet of users. This is used when searching for users to impersonate, when listing what users to impersonate, and when trying to start impersonation. Settings -------- The following settings are available for django-impersonate: IMPERSONATE_REDIRECT_URL This is the URL you want to be redirected to after you have chosen to impersonate another user. If this is not present it will check for the LOGIN_REDIRECT_URL setting and fall back to '/' if neither is present. Value should be a string containing the redirect path. IMPERSONATE_PAGINATE_COUNT This is the number of users to paginate by when using the list or search views. This defaults to 20. Value should be an integer. IMPERSONATE_REQUIRE_SUPERUSER If this is set to True, then only users who have 'is_superuser' set to True will be allowed to impersonate other users. Default is False. If False, then any 'is_staff' user will be able to impersonate other users. Note: Regardless of this setting, a 'is_staff' user will *not* be allowed to impersonate a 'is_superuser' user. Value should be a boolean (True/False) If the IMPERSONATE_CUSTOM_ALLOW is set, then that custom function is used, and this setting is ignored. IMPERSONATE_URI_EXCLUSIONS Set to a list/tuple of url patterns that, if matched, user impersonation is not completed. It defaults to: (r'^admin/',) If you do not want to use even the default exclusions then set the setting to an emply list/tuple. IMPERSONATE_CUSTOM_USER_QUERYSET A string that represents a function (e.g. 'module.submodule.mod.function_name') that allows more fine grained control over what users a user can impersonate. It takes one argument, the request object, and should return a QuerySet. Only the users in this queryset can be impersonated. This function will not be called when the request has an unauthorised users, and will only be called when the user is allowed to impersonate (cf. IMPERSONATE_REQUIRE_SUPERUSER and IMPERSONATE_CUSTOM_ALLOW ) Regardless of what this function returns, a user cannot impersonate a superuser, even if there are superusers in the returned QuerySet. It is optional, and if it is not present, the user can impersonate any user (i.e. the default is User.objects.all()) IMPERSONATE_CUSTOM_ALLOW A string that represents a function (e.g. 'module.submodule.mod.function_name') that allows more fine grained control over who can use the impersonation. It takes one argument, the request object, and should return True to allow impesonation. Regardless of this setting, the user must be logged in to impersonate. If this setting is used, IMPERSONATE_REQUIRE_SUPERUSER is ignored. It is optional, and if it is not present, the previous rules about superuser and IMPERSONATE_REQUIRE_SUPERUSER apply.
