I18n Phoenix Router Segment

Question

I have an Elixir / Phoenix application that reacts differently depending on the domain (aka tenant).

The tenant has a specific language, such as "fr_FR", "en_US", etc.

I want to translate the router URI depending on the current locale :

# EN
get "/classifieds/new", ClassifiedController, :new

# FR
get "/annonces/ajout", ClassifiedController, :new

So far, I thought it would be possible to do something like this (pseudo-code):

if locale() == :fr do

    scope "/", Awesome.App, as: :app do
        pipe_through :browser # Use the default browser stack
        get "/annonces/ajout", ClassifiedController, :new
    end

else

    scope "/", Awesome.App, as: :app do
        pipe_through :browser # Use the default browser stack
        get "/classifieds/new", ClassifiedController, :new
    end

end

This does not work, since the router was compiled during server boot, so you do not have the context of the current connection (locale, domain, host, etc.).

So far, my solution (which works) has been to create two areas with two aliases:

scope "/", Awesome.App, as: :fr_app do
  pipe_through :browser # Use the default browser stack
  get "/annonces/ajout", ClassifiedController, :new
end

scope "/", Awesome.App, as: :app do
  pipe_through :browser # Use the default browser stack
  get "/classifieds/new", ClassifiedController, :new
end

and associate assistant:

localized_path(conn, path, action)

(: app_classified_new_path) fr (: fr_app_classified_new_path), " fr" (). , "ru" ).

, :

• "something_foo_path()" "localized_path()"

• (fr, en, it, whatever), , ( , fr "fr"

• locale/conn (/bugfix?) .
