如何讓搜索表單實際執行搜索查詢（在Rails中）

Question

我有一個搜索表單，我從this tutorial創建。但是，如何讓它爲指定的控制器和指定的操作執行實際查詢？

%form 
    %input{:placeholder => "Find something...", :required => "", :type => "text"} 
    %button{:type => "submit"} Search 

Answer 1

你需要把目標爲以下形式：

%form{ :action => "/rotas", :method => "get" } 
    %input{:placeholder => "Find something...", :required => "", :type => "text"} 
    %button{:type => "submit"} Search 

或者你可以使用form_tag helper，像：

=form_tag(controller: :posts , action: :index, method: :get) do |f| 
    = f.text_field :query, nil, :placeholder => "Find something..." 
    = f.submit "Search" 

，記得留意indentations！
