Question

我很高兴在控制器中设置flash消息，如下所示：

redirect_to root_path, error: 'This is a highly eloquent and specialised error message just for you, my iridescent, transcendent and all round marvellous bundle of joy! You are not allowed in here you cheeky chappy, you!'

然而，我发现在编写功能规范以测试这些消息正在呈现时，我正在进行大量的复制粘贴：

context 'when user has eaten all the pies' do
   let(:cheeky) { FactoryGirl.build(:cheeky_user) }
   subject { page }

   before do
     log_in cheeky
     click_link 'steal pies'
   end

   it_should_behave_like 'home page'
   it{ should have_selector('.error', text: 'This is a highly eloquent and specialised error message just for you, my iridescent, transcendent and all round marvellous bundle of joy! You are not allowed in here you cheeky chappy, you!') }
end

当一个断言因为我缺少一个字符而失败时会很痛苦，但更多的是，当得到一堆失败的规范时，因为我已经调整了一些错误消息。

测试错误消息这可能是一个脆弱的规范的例子，但我想测试正在显示的错误消息。

我真的希望能够做到这一点：

#somewhere in rails
ERROR_MSG_23 = 'This is a highly eloquent and specialised error message just for you, my iridescent, transcendent and all round marvellous bundle of joy! You are not allowed in here you cheeky chappy, you!'

#controller
redirect_to root_path, error: ERROR_MSG_23

#spec
context 'when user has eaten all the pies' do
   let(:cheeky) { FactoryGirl.build(:cheeky_user) }
   subject { page }

   before do
     log_in cheeky
     click_link 'steal pies'
   end

   it_should_behave_like 'home page'
   it{ should have_selector('.error', text: ERROR_MSG_23 ) }
end

这有宝石吗？或者这可以在vanilla rails中实现吗？

Answer 1

您可以使用I18n，如下所示：

en.yml：

en:
  flash_messages:
    message_1: 'This is a highly eloquent and specialised error message just for you, my iridescent, transcendent and all round marvellous bundle of joy! You are not allowed in here you cheeky chappy, you!'

控制器：

redirect_to root_path, error: t('flash_messages.message_1')

规格：

it{ should have_selector('.error', text: I18n.t('flash_messages.message_1') }

有没有地方可以在rails中设置“全局”Flash消息？
