Route Helpers on forwarded routes and nested routers

[simonp...@gmail.com]

Hi,

I’ve been using many routers to separate routing logics. This means that my router looks like this:

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

  scope "/", AccentApi do
    forward "languages", Routers.Languages
  end
end

And my Routers.Languages looks like:

defmodule AccentApi.Routers.Languages do
  use AccentApi.Web, :router

  scope "/", AccentApi do
    get "/", LanguageController, :index
    get "/:language_id", LanguageController, :show
  end
end

Problem is, when using the AccentApi.Routers.Languages.Helper.language_path(:show, 1), the result is "/1". This is because the scope is "/" and the actual route "/languages/1" is catched by the forward function in the main Router.

Is their an easy way to use route helpers with forwarded routes? Or am I doing something wrong?

Thanks!

Hi,

You could try something along the lines of "/languages" <> AccentApi.Routers.Languages.Helper.language_path(:show, 1)

What output do you get when you run `mix phoenix.routes` in the command line?

.
The plug conn struct has fields path_info and script_name have path information that might be of use.

If you pass the `conn` to the route helper, it will maintain the prefix. Without the conn, there is no context to build the prefix with.
