Programming Phoenix error: function Routes.user_path/3 is undefined (module Routes is not available)

Did You update the router file?

@kokolegorille It looks like the following,

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

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

You can use mix phx.routes to view path helpers.

Try to remove Routes.

It might be a typo

Update: Or a new feature of version 1.4

If you take a look at this video, the Routes.<some>_path will be used in phoenix 1.4

I don’t think it’s available in 1.3.2

This is the output of mix phx.routes

remove Routes. as @kokolegorille said

What do you mean by removing routes, do you mean to remove the two lines,

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

, from router.ex ?

In the template…

<%= link "View", to: Routes.user_path(@conn, :show, user.id) %>
