Elixir Phoenix.Route.NoRouteError

Question

I'm going through the book "Programming Phoenix" and after adding the /Users/New route around page 60, my router seems to have stopped functioning properly.

When I try to navigate to any /Users route I get

"no route found for GET /Users (Rumbl.Router)"

my router.ex file looks like this:

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

  pipeline :browser do
    plug :accepts, ["html"]
    plug :fetch_session
    plug :fetch_flash
    plug :protect_from_forgery
    plug :put_secure_browser_headers
  end

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

  scope "/", Rumbl do
    pipe_through :browser # Use the default browser stack

    get "/", PageController, :index
    resources "/users", UserController, only: [:index, :show, :new, :create]

  end

end

My controller looks like this:

defmodule Rumbl.UserController do
  use Rumbl.Web, :controller
  alias Rumbl.User

  def index(conn, _params) do
    users = Repo.all(User)
    render conn, "index.html", users: users
  end

  def show(conn, %{"id" => id}) do
    user = Repo.get(User, id)
    render conn, "show.html", user: user
  end

  def new(conn, _params) do
    changeset = User.changeset(%User{})
    render conn, "new.html", changeset: changeset
  end

end

running "mix phoenix.routes" returns:

page_path  GET   /           Rumbl.PageController :index
user_path  GET   /users      Rumbl.UserController :index
user_path  GET   /users/new  Rumbl.UserController :new
user_path  GET   /users/:id  Rumbl.UserController :show
user_path  POST  /users      Rumbl.UserController :create

It worked fine up until adding the "new" route. I've tried removing the new route(and everything that came with it) and going back to the way it was before with just

get "/users", UserController, :index
get "/users/:id", UserController, :show

and it still doesn't work.

I've restarted the phoenix server and tried recreating the router.ex file from scratch. I'm at a loss, what could be going on here?

Here is the stack trace:

Answer 1

/Users and /users are not the same.

Try to use downcased version of paths: /users , /users/new .
