ROR：语法错误，意想不到的tSTRING_BEG，期待keyword_do或 '{' 或 '（'（的SyntaxError）

Question

我尝试我的第一个Rails应用程序

但得到了以下错误：

/Users/WWW/.rvm/gems/ruby-2.1.5/gems/activesupport-4.2.0/lib/active_support/dependencies.rb:268:in `load': /Users/WWW/railsbridge/first-app/config/routes.rb:3: syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '(' (SyntaxError) 
+ get 'welcome',to: 'topics#welcome' 
    ^
/Users/WWW/railsbridge/first-app/config/routes.rb:3: syntax error, unexpected ',', expecting keyword_end 
+ get 'welcome',to: 'topics#welcome' 

这里是代码：

resources :topics 
+ get 'welcome',to: 'topics#welcome' 

Answer 1

你必须定义一个do .. end块像这里面的路线：

resources :topics do 
    get 'welcome', to: 'topics#welcome' 
    end 

我强烈建议您阅读Official Ruby on Rails Documentation for Routing

Answer 2

以及阅读的指南，以帮助您开始如上面提到的，还读代码所提供的意见，以帮助您开始。该文件的routes.rb是一个很好的例子：

# The priority is based upon order of creation: first created -> highest priority. 
    # See how all your routes lay out with "rake routes". 

    # You can have the root of your site routed with "root" 
    # root 'welcome#index' 

    # Example of regular route: 
    # get 'products/:id' => 'catalog#view' 

    # Example of named route that can be invoked with purchase_url(id: product.id) 
    # get 'products/:id/purchase' => 'catalog#purchase', as: :purchase 

等等
