Phoenix framework router.ex config for JSON

I've installed phoenix JSON package through mix phoenix.gen.json V1.Post posts title:string content:string secret:string --no-model but got this error:

== Compilation error on file web/controllers/v1/post_controller.ex ==
** (CompileError) web/controllers/v1/post_controller.ex:14: Shopper.V1.Post.__struct__/0 is undefined, cannot expand struct Shopper.V1.Post
(elixir) src/elixir_map.erl:55: :elixir_map.translate_struct/4
(stdlib) lists.erl:1353: :lists.mapfoldl/3
(elixir) src/elixir_clauses.erl:36: :elixir_clauses.clause/7

web/controllers/v1/post_controller.ex:13: (module)
(stdlib) erl_eval.erl:669: :erl_eval.do_apply/6

here is my router.ex code:

defmodule Shopper.Router do
use Shopper.Web, :router

pipeline :api do
    plug :accepts, ["json"]
end

scope "/", Shopper do
    pipe_through :api
    resources "/v1/posts", V1.PostController
end
end

From the documentation said:

Add the resource to the proper scope in web/router.ex:

resources "/posts", PostController

But.. I can't make it work, could anybody help me? Thank you.

Please note that this is for phoenix 1.0 and elixir 1.0.

My question is pointing to wrong problem, but I'll keep it that way so it can help people who coming with similar conclusion.

The solution is to add a model for V1.Post but running mix phoenix.gen.model will give a compile error which already stated in my question. So, I must comment the offending code which is the entire def create(conn, %{"post" => post_params}) in V1.Post controller.

After that run mix phoenix.gen.model V1.Post posts name:string then uncomment the offending code.

To test, run mix phoenix.routes which in my case returning

Compiled web/models/v1/post.ex
Generated shopper app
page_path  GET     /                  Shopper.PageController :index
post_path  GET     /api/v1/posts      Shopper.V1.PostController :index
post_path  GET     /api/v1/posts/:id  Shopper.V1.PostController :show
post_path  POST    /api/v1/posts      Shopper.V1.PostController :create
post_path  PATCH   /api/v1/posts/:id  Shopper.V1.PostController :update
           PUT     /api/v1/posts/:id  Shopper.V1.PostController :update
post_path  DELETE  /api/v1/posts/:id  Shopper.V1.PostController :delete

Success!
