Every method that requires an authenticated user can now be annotated with @before!ensureAuth("_authUser"). This is a lot to type. Therefore, you define a shortcut:private enum auth = before!ensureAuth("_authUser");

The methods can now be annotated with @auth. Do not forget to add a string _authUser parameter, too:void index(string _error = null) { render!("index.dt", _error); } @errorDisplay!index void postLogin(string username, string password) { import std.uuid : randomUUID; enforce(username == "yourid" && password == "secret", "Invalid username / password"); UserData d; d.loggedIn = true; d.name = username; d.uuid = randomUUID.toString; user = d; redirect("/listnotes"); } @auth void getListnotes(string _authUser) { auto allnotes = noteStore.getNotes(user.uuid); render!("listnotes.dt", allnotes); } @method(HTTPMethod.GET) void logout() { user = UserData.init; terminateSession(); redirect("/"); } @auth void getNoteEntry(string _authUser, ValidationErrorData _error = ValidationErrorData.init) { render!("create.dt", _error); } @auth @errorDisplay!getNoteEntry void createNewNote(string _authUser, ValidTopic form_topic, string form_content) { Note note; note.topic = form_topic; note.content = form_content; auto allnotes = noteStore.getNotes(user.uuid); allnotes ~= note; noteStore.setNotes(user.uuid, allnotes); redirect("/listnotes"); }
