Unlocalized route path does not work in non-feature specs

[jensb]

What can be the reason if I have route helpers that - when called with a specific locale set - always return the default translation, not the translated route? E.g.

> app.products_path
=> "/products"                    # OK
> I18n.locale = 'de'
=> "de"
> app.products_de_path
=> "/produkte"                    # OK
> app.products_path
=> "/products"                    # should return "/produkte" since I18n.locale is 'de'! Right?

Settings:

RouteTranslator.config do |c|
  c.hide_locale = true
  c.generate_unlocalized_routes = true
end

Using Rails 4.2. Please advise where I should start to debug, I'd like to help track this and will provide a patch if I find a bug. Thank you!

I think it depends on generate_unlocalized_routes

generate_unlocalized_routes Set this option to true to add translated routes without deleting original unlocalized versions. Autosets force_locale=true. Defaults to false.

I would say that products_path is the original, unlocalized version and it behaves like that.

Relevant code: https://github.com/enriclluelles/route_translator/blob/master/lib/route_translator/extensions/route_set.rb#L13

        elsif RouteTranslator.config.generate_unlocalized_routes
          add_route app, conditions, requirements, defaults, as, anchor
        end

Leaving this open for further discussion

Thank you - this works, but then I am missing some untranslated named route helpers in my rspec tests - strangely, only in tests. In devel mode the routes exist and work. Example:

localized do
  get 'foobar-whatever-:id' => 'foobar#whatever', as: foobar, constraints: { id: /\d+/ }
  # ...
end

With generate_unlocalized_routes = true, rake routes will result in routes like foobar_en, foobar_de but foobar is missing. However, in devel mode (and I hope in production mode too) foobar_path and foobar_url still work fine and actually respect I18n.locale! Any idea what can make this happen?

[tagliala]

Sorry but I cannot confirm

RouteTranslator.config do |config|
  config.force_locale = true
end

$ rails c test
Loading test environment (Rails 3.2.22.2)
[1] pry(main)> app.galleries_path
=> "/en/galleries"
[2] pry(main)> app.galleries_en_path
=> "/en/galleries"
[3] pry(main)> app.galleries_es_path
=> "/es/galerias"

$ rails c test
Loading test environment (Rails 4.2.5.2)
[1] pry(main)> app.press_releases_path
=> "/it/comunicati-stampa"
[2] pry(main)> app.press_releases_en_path
=> "/en/press-releases"
[3] pry(main)> app.press_releases_it_path
=> "/it/comunicati-stampa"
[4] pry(main)> 

Could you please provide a failing test case or application?

[jensb]

Will do. It only fails in my rspec tests when I use the helpers, not in the console or in the app. Very strange.

I'm also using rspec tests and I got the issue.

require 'spec_helper'

describe 'Route translator' do
  it "shows localized and unlocalized routes" do
    visit press_releases_path
    visit press_releases_en_path
    visit press_releases_it_path
  end
end

Please try with type: :feature, I will investigate this but help would be appreciated

@jensb is it possible to use url helpers outside feature specs? This question is not related to route_translator

[jensb]

In my controller specs, I include ActionView::Helpers::UrlHelper and include Rails.application.routes.url_helpers to use routing helpers. This has worked since Rails 3.0.

But the routing issue gets even stranger - in development mode rake routes does not print the nontranslated (missing) routes but they still work when the app is started from Apache Passenger. Using feature specs, translated routes work within the spec, however, I still get a ActionController::UrlGenerationError with some routing specs. I'm looking into this.

any solution for this yet?

I know last post was several years ago, but in case anyone runs into this again, it seems to be that the issue arrises due to not mixing in the dynamically defined unlocalized route helpers into the base classes of the testing suite, which happens here.

To get these methods to work on specs that do not inherit from ActionController::TestCase, ActionMailer::TestCase, ActionView::TestCase, you need to include the helper_container into the base class of your specs -- in RSpec, this is RSpec::Core::ExampleGroup.

def add_helpers_to_rspec(helper_container)
  return unless Module.const_defined?('RSpec::Core::ExampleGroup')

  RSpec::Core::ExampleGroup.__send__(:include, helper_container)
end

I've currently modified this to be:

if ENV['RAILS_ENV'] == 'test'
  add_helpers_to_test_cases(helper_container)
  add_helpers_to_rspec(helper_container)
end

Hope this helps, if needed.
