Package: datapunt-django-audit-log
For the Python only implementation (which is used by this library) seehttps://github.com/Amsterdam/python-audit-logDataPunt Django Audit LogDataPunt Audit Log is a simple Django app that will log all incoming requests
and their corresponding responses to a configurable endpoint.During the process request phase, the logger is attached to the request. Before
returning a response the app can easily provide extra context. In the process
response phase the audit_log middleware will send the log.LinksQuick StartDefault Context InfoCustom Optional Context InfoDjango Rest FrameworkQuick startInstall using pippipinstalldatapunt_django_audit_logAdd "django_audit_log" to your INSTALLED_APPS:INSTALLED_APPS=[...'django_audit_log',]Add the AuditLogMiddleware to your MIDDLEWARE:MIDDLEWARE=[...'django_audit_log.middleware.AuditLogMiddleware',]When using the Django Rest Framework, let your viewsets extendAuditLogReadOnlyViewsetorAuditLogViewSet. This will automatically add context to the audit log regarding
filters, results and executed actions (see -Django Rest Framework).classMyViewSet(AuditLogViewSet):queryset=SomeModel.objects.all()Set the AUDIT_LOG_EXEMPT_URLS setting to make sure certain urls will not be logged
(e.g. health check urls).# If a URL path matches a regular expression in this list, the request will not be redirected to HTTPS.# The AuditLogMiddleware strips leading slashes from URL paths, so patterns shouldn’t include them, e.g.# [r'foo/bar$']AUDIT_LOG_EXEMPT_URLS=[]At this point all requests/responses will be logged. For providing extra context
(which you are strongly urged to do so), see next chapters.Default context infoBy default the audit log sends the following json structure per request:{"http_request":{"method":"get|post|head|options|etc..","url":"https://datapunt.amsterdam.nl?including=querystring","user_agent":"full browser user agent"},"http_response":{"status_code":"http status code","reason":"http status reason","headers":{"key":"value"}},"user":{"authenticated":"True/False","provider":"auth backend the user authenticated with","realm":"optional realm when using keycloak or another provider","email":"email of logged in user","roles":"roles attached to the logged in user","ip":"ip address"}}Each json entry is set by its corresponding method. In this case,
the middleware sets them automatically by callingset_http_request()andset_user_fom_request()in the process_request method. In the process_response method the
last data is set by invokingset_http_response().After the response has been processed the middleware automatically
creates the log item by callingsend_log().Custom optional context infoPer request it is possible to add optional context info. For a complete
audit log, you are strongly urged to add more info inside your view.Adding extra context is quite simple. The audit_log object has been added
to the request by the middleware. Therefore every view can simply access
it via the request object.Filterrequest.audit_log.set_filter(self, object_name, fields, terms)allows to provide
info on the requested type of object and the filters that have been used
(a user searches for 'terms', which are matched on specific 'fields' of the
'object').This method will add the following details to the log:"filter":{"object":"Object name that is requested","fields":"Fields that are being filtered on, if applicable","terms":"Search terms, if applicable"}Resultsrequest.audit_log.set_results(self, results)allows to pass a json dict
detailing exactly what results have been returned to the user.It is up to the developer to decide whether the amount of
data that would be added here will become a burden instead
of a blessing.This method will add the following details to the log:"results":{...}Message and loglevelAt last, a log message and loglevel can be provided to indicate
what the request is actually doing. This is done by calling
one of the following methods:request.audit_log.debug(self,msg)request.audit_log.info(self,msg)request.audit_log.warning(self,msg)request.audit_log.error(self,msg)request.audit_log.critical(self,msg)These methods will add the following details to the log:"type":"DEBUG|INFO|WARNING|ERROR|etc","message":"log message"Django Rest FrameworkTwo base-ViewSets are available if you use the Django Rest Framework.TheAuditLogReadOnlyViewSetextends theReadOnlyModelViewSetand overrides
theretrieve()andlist()methods. TheAuditLogViewSetextends theAuditLogReadOnlyViewSetand overrides the remaining (non-read-only) methodscreate(),update()anddestroy().Our classes inspect the request and will automatically add extra context information
to the audit log. This context information provides info regarding filters, results
and the action that is being performed.Note that by defaultlist()will not add the results to the log, unless theaudit_log_list_responseattribute is set. Only do so when the amount of data inside the list response is suitable
to store inside a log entry.classMyViewSet(AuditLogViewSet):audit_log_list_response=True
