I’m using Programming Phoenix by Chris McCord as a reference to build my personal blog. I’ve replicated the authentication implementation almost exactly, but now that I am working through the chapter about testing the authentication plug, I’m getting (Plug.Conn.AlreadySentError) the response was alr…

Wow, I’m dumb :stuck_out_tongue: Turns out I forgot to change bypass_through(Rumbl.Router, :browser) to bypass_through(PhoenixBlog.Router, :browser) after I pasted the code from the book. Thanks Jose for your help and to @luke on Slack for talking the problem out with me and helping me fix it …

I believe you need to call conn = recycle(conn) after using the connection if you want to do another request with it.

I’m not sure exactly where I would put that function, but I put it in the setup callback like so: setup %{conn: conn} do conn = conn |> recycle() |> bypass_through(Rumbl.Router, :browser) |> get("/") {:ok, %{conn: conn}} end However that still did not fix my problem :confused: …

Now I get: 1) test authenticate_user halts when no current_user exists (PhoenixBlog.AuthTest) test/plugs/auth_test.exs:15 ** (KeyError) key :current_user not found in: %{} stacktrace: (phoenix_blog) web/plugs/auth.ex:52: PhoenixBlog.Plugs.Auth.authenticate_user/2 test/plugs/auth_…

For anybody who reads newer version of the book, please check that you bypass through right namespace: RumblWeb instead of Rumbl. setup %{conn: conn} do conn = conn |> bypass_through(RumblWeb.Router, :browser) |> get("/") {:ok, %{conn: conn}} end I had similar problem too

I am getting the same problem working through the >= 1.4 version of the book. It starts failing on test “requires user authentication on all actions”
