undefined function: MyApp.Addict.Controller.init/1

Question

I am using addict with Phoenix: 1.0.3, I have followed README guide to use login in my app. I am getting following error when I make a call to login:

[error] #PID<0.2576.0> running MyApp.Endpoint terminated
Server: localhost:4000 (http)
Request: POST /login
** (exit) an exception was raised:
** (UndefinedFunctionError) undefined function: MyApp.Addict.Controller.init/1 (module MyApp.Addict.Controller is not available)

Answer 1

This was due to my following error in router.ex:

  scope "/", MyApp do
    addict :routes
  end

This should had been:

  scope "/" do
    addict :routes
  end

Answer 2

In my case the error was solved by running:

$ mix deps.compile --force 

The controller that produced the errors had existed for a while and there was a controller test that didn't report any errors.
