应用 i18n 后 RSpec 测试中断

Question

在完成RailsTutorial.org 之后，我决定 i18n 我的应用程序，但突然我的测试开始失败并出现以下问题，

失败：

1) 用户页面索引 失败/错误：登录用户 水豚::ElementNotFound: 找不到“电子邮件”字段 # ./spec/support/utilities.rb:5:in sign_in' # ./spec/requests/user_pages_spec.rb:11:inblock (3 级)

我在哪里做的唯一改变，

routes.rb

SampleApp::Application.routes.draw do
  scope '(:locale)' do
    resources :users
    resources :sessions, only: [:new, :create, :destroy]
    root to: 'static_pages#home'
    match '/signup',    to: 'users#new',              via: 'get'
    match '/signin',    to: 'sessions#new',           via: 'get'
    match '/signout',   to: 'sessions#destroy',       via: 'delete'
    match '/help',      to: 'static_pages#help',      via: 'get'
    match '/about',     to: 'static_pages#about',     via: 'get'
    match '/contact',   to: 'static_pages#contact',   via: 'get'
  end

还有 config/initializers/i18n.rb

I18n.default_locale = :en

LANGUAGES = [
  ['English',               'en'],
  ['Portuguese',        'pt']
]

在 i18n 之前，路线如下所示，

users_path  GET     /users(.:format)    users#index
    POST    /users(.:format)    users#create
new_user_path   GET     /users/new(.:format)    users#new
edit_user_path  GET     /users/:id/edit(.:format)   users#edit
user_path   GET     /users/:id(.:format)    users#show
    PATCH   /users/:id(.:format)    users#update
    PUT     /users/:id(.:format)    users#update
    DELETE  /users/:id(.:format)    users#destroy
sessions_path   POST    /sessions(.:format)     sessions#create
new_session_path    GET     /sessions/new(.:format)     sessions#new
session_path    DELETE  /sessions/:id(.:format)     sessions#destroy
root_path   GET     /   static_pages#home
signup_path     GET     /signup(.:format)   users#new
signin_path     GET     /signin(.:format)   sessions#new
signout_path    DELETE  /signout(.:format)  sessions#destroy
help_path   GET     /help(.:format)     static_pages#help
about_path  GET     /about(.:format)    static_pages#about
contact_path    GET     /contact(.:format)  static_pages#contact 

现在，

users_path  GET     (/:locale)/users(.:format)  users#index
    POST    (/:locale)/users(.:format)  users#create

user_path   GET     (/:locale)/users/:id(.:format)  users#show
    PATCH   (/:locale)/users/:id(.:format)  users#update
    PUT     (/:locale)/users/:id(.:format)  users#update
    DELETE  (/:locale)/users/:id(.:format)  users#destroy
sessions_path   POST    (/:locale)/sessions(.:format)   sessions#create
new_session_path    GET     (/:locale)/sessions/new(.:format)   sessions#new
session_path    DELETE  (/:locale)/sessions/:id(.:format)   sessions#destroy
root_path   GET     /(:locale)(.:format)    static_pages#home
signup_path     GET     (/:locale)/signup(.:format)     users#new
signin_path     GET     (/:locale)/signin(.:format)     sessions#new
signout_path    DELETE  (/:locale)/signout(.:format)    sessions#destroy
help_path   GET     (/:locale)/help(.:format)   static_pages#help
about_path  GET     (/:locale)/about(.:format)  static_pages#about
contact_path    GET     (/:locale)/contact(.:format)    static_pages#contact

有人可以为初学者提供一些提示吗？ 感谢大家的支持。

Answer 1

如果您要将所有路由的范围设置为包含locale，则需要在测试它们时将locale 传递到您的路径中（正如您在@987654324 的新输出中看到的那样@，应该是:locale），所以你应该在哪里放，比如visit users_path，你应该放
visit users_path(locale)。您将从I18n.available_locales 列表中获得您的locale。您还需要将用于查找字段的字符串更改为对应的 i18n，例如
fill_in "Email" 变为 fill_in I18n.t('sessions.new.email')

我对我的示例应用程序进行了 i18n 化处理，因此 here's my user_pages_spec.rb 希望能让您了解您可能需要进行哪些更改。
