路由:无法获取默认范围(:locale)以使用user_path(id),始终必须明确提交区域设置

标签: ruby-on-rails internationalization locale

我已经对这个话题进行了一些研究,但我似乎无法弄明白。

我已经按照official guide设置了I18n,但我没有正确设置默认语言环境(当没有指定明确的语言环境时)。

# routes.rb
require 'sidekiq/web'

Iq::Application.routes.draw do
  scope "(:locale)", locale: /de|en/ do
    # ...
  end
end

# application_controller.rb
class ApplicationController < ActionController::Base
  before_filter :set_language

  def set_language
    I18n.locale = params[:locale] || I18n.default_locale
  end

  def default_url_options(options = {})
    options.merge!({ :locale => I18n.locale })
  end
end

在OS X控制台中:

$ rake routes | grep user
...
user GET      (/:locale)/users/:id(.:format)   users#show {:locale=>/de|en/}
...

在Rails控制台中:

$ Rails c
$ app.users_path
=> "/users"
app.users_path locale: :de
=> "/de/users"
$ app.user_path User.first, locale: :de
=> "/de/users/509fc01d77bb1e6a050000a0"
$ app.user_path User.first
ActionController::RoutingError: No route matches {:action=>"show", :controller=>"users", :locale=>#<User _id: 509fc01d77bb1e6a050000a0, _type: nil, created_at: 2012-11-11 15:11:25 UTC, updated_at: 2012-11-11 15:11:25 UTC, deleted_at: nil, group: "administrator", language: "de", active: true, sign_in_count: 0, name: "sysadmin", email: "support@sientia.ch", encrypted_password: "$2a$10$n/b7sTmUjEMoZI/jvq2jPuaNQqo1R1zbAIPpko9HT9PERagXclrPK", reset_password_token: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, confirmation_token: nil, unconfirmed_email: nil, reset_password_sent_at: nil, remember_created_at: nil, confirmed_at: 2012-11-11 15:11:25 UTC, confirmation_sent_at: nil, current_sign_in_at: nil, last_sign_in_at: nil, save_vertical_menu_visibility_state: nil, contact_id: "509fc01d77bb1e6a0500008c", contact_name: "Sientia AG">}

为什么这不起作用?我忘记了什么?

非常感谢你的帮助, 约什

答案 0 :(得分:0)

一位同事A对此进行了调查,并决定不将(:locale)放入括号中。另一位同事B提到,他把它放在括号中,以便我们的测试工作,我们不想在调用url helper方法时明确指定语言环境。

同事A提到,当没有语言环境调用url helper方法时,应用程序本身会回退到上面提到的default_url_options方法。这很好,因为除了root_path之外,我们总是想要一个明确的语言集。

在测试中,default_url_options方法被忽略(我不确定这是一个错误还是一个功能,哈哈)。所以必须做一些解决方法:

# Fixes the missing default locale problem in request specs.
# See http://www.ruby-forum.com/topic/3448797
class ActionView::TestCase::TestController
  def default_url_options(options={})
    { :locale => I18n.default_locale }
  end
end

class ActionDispatch::Routing::RouteSet
  def default_url_options(options={})
    { :locale => I18n.default_locale }
  end
end

# Fixes the missing default locale problem in controller specs
# See http://www.ruby-forum.com/topic/3448797#1041659
class ActionController::TestCase
  module Behavior
    def process_with_default_locale(action, parameters = nil, session = nil, flash = nil, http_method = 'GET')
      parameters = { :locale => I18n.default_locale }.merge( parameters || {} )
      process_without_default_locale(action, parameters, session, flash, http_method)
    end
    alias_method_chain :process, :default_locale
  end
end

module ActionDispatch::Assertions::RoutingAssertions
  def assert_recognizes_with_default_locale(expected_options, path, extras = {}, message=nil)
    expected_options = { :locale => I18n.default_locale.to_s }.merge(expected_options || {} )
    assert_recognizes_without_default_locale(expected_options, path, extras, message)
  end
  alias_method_chain :assert_recognizes, :default_locale
end

将它放入spec_helper.rb文件中,您就可以使用控制器并请求规格了! : - )

但是,在控制台中,这似乎没有办法:

$ app.user_path User.first
ActionController::RoutingError: No route matches...
