Rather than redirect, replay?

[Bryan Hunt]

Hi,

I'm working away on my first Chicagoboss demo application, and I'm trying to implement an identification, authorization, access workflow.

---

I started by implementing a controller_filter:

-module(training_filter).

-export([before_filter/2]).

before_filter(_FilterConfig, RequestContext) ->
  SessionId = proplists:get_value(session_id, RequestContext),
%%   Request = proplists:get_value(request, RequestContext),
  lager:log(info, self(), " before filter invoked", []),
  Action = proplists:get_value(action, RequestContext),
  case boss_session:get_session_data(SessionId, username) of
    undefined when Action == "login" ->
      {ok, RequestContext};
    undefined ->
      lager:log(error, self(), " failed to grab user from session/RequestContext ~p", [RequestContext]),
      boss_session:set_session_data(SessionId, original_request_context, RequestContext),
      {redirect, "/login"}
  end.

---

I then implemented a (laughably) trivial login module:

-module(training_security_controller, [Req, SessionID]).
-compile(export_all).

login('POST', []) ->
  User = Req:post_param("username"),
  Password = Req:post_param("password"),
  lager:log(info, self(), "~p ~p", [User, Password]),
  case Password of
    "foo" ->
      boss_session:set_session_data(SessionID, username, User),
      OriginalRequestContext = boss_session:get_session_data(SessionID, original_request_context),
      %but I really want to replay the original request
      {redirect, "/"}

  ;
    _ ->
      boss_flash:add(SessionID, notice, "Login", "Bad credentials, try again!"),
      {ok, login}
  end
;

login('GET', []) ->
  boss_flash:add(SessionID, notice, "Login", "Enter your password!"),
  {ok, login}.

What I would like to do is call the originally requested controller, with the OriginalRequestContext taken from the session, and let it handle the return/output.

Is such a thing possible ? I've done some digging but can't find any relevant examples.

Thanks,

Bryan

Thanks can2nac.

I also found out about the (very useful) 'action_other' response from the docs page.

In my simple case I used it like so:

{action_other, [{controller, "base"}, {action, "index"}]} ;

I will read over the like you provided.
