Feature request: custom translation for nested resources

[cspeer]

Steps to reproduce*

Expected behavior*

I have defined my route translations like this:

de:
  routes:
    products: produkte
    controllers:
      admin:
        products: produkte2

and my routes like this:

Rails.application.routes.draw do
  localized do
    resources :products

    namespace :admin do
      resources :products
    end
  end
end

My expectation is that, apart from the english routes, I would get the following ones:

• /de/produkte
• /de/admin/produkte2

Actual behavior*

Instead I get these routes:

• /de/produkte
• /de/admin/produkte

If I leave out the controllers part in my translation file like this:

de:
  routes:
    products: produkte
    admin:
      products: produkte2

The app won't boot anymore and I get this error:

Can't convert Hash into String

System configuration*

Rails version:
Rails 6.1.4.4
Ruby version:
ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-darwin20]
Route Translator version:
route_translator (12.1.0)

I18n configuration*

require_relative "boot"

require "rails/all"

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module RoutingI18n
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 6.1

    # Configuration for the application, engines, and railties goes here.
    #
    # These settings can be overridden in specific environments using the files
    # in config/environments, which are processed later.
    #
    # config.time_zone = "Central Time (US & Canada)"
    # config.eager_load_paths << Rails.root.join("extras")

    I18n.available_locales = [:en, :de]
    I18n.default_locale = :en
  end
end

Hi,

thanks for the thorough description of the issue and apologies for the late reply.

I'm surprised too of this behavior, and I've silently tried to investigate and fix this issue just after it has been reported

I do not have much time to invest on route translator, and I'm not using this gem in production environments for at least 3/4 years, so any help and a PR with tests are welcomed.

I'm going to consider this a feature request

At the moment route_translator allows to translate an individual route inside a namespaced controller as described in the readme: https://github.com/enriclluelles/route_translator#translations-for-similar-routes-with-different-namespaces

A new feature to support custom translations of namespaced resources must not use controllers: namespace, because otherwise it will break the existing functionality

### Nope
routes:
  controllers:
    namespace:
      resource: translation # This will break the existing functionality to translate namespaced routes

It is also not possible to use

### Nope
routes:
  namespace:
    resource: translation # This will break an existing functionality to translate namespaces themselves

Because otherwise it will not be possible to translate the namespace itself

Probably we can use something à-la ActiveModel like namespace/resource: https://api.rubyonrails.org/classes/ActiveModel/Naming.html

I completely unterstand @tagliala
I'd chip in here but I'm also rather strapped for time right now.

Actually this is already supported and, in retrospect, it was trivial enough 😅

I've added a readme entry and a test case to help

Solution:

de:
  routes:
    products: produkte
    controllers:
      admin:
        products:
          products: produkte2

[cspeer]

oh, and it makes so much sense 😅
Thanks a lot @tagliala
