Question

我为以下控制器定义了以下路由get 'search', to: 'search#show'：

class SearchController < Application Controller
  def show
    @users = User.where( { username: params[:query] } )
    respond_to do |format|
      format.html
    end
  end
end

我有一个views/application/_search.html.erb上的搜索表

<%= form_with method: :get, url: search_path do |form| %>
  <div class="field">
    <%= form.text_field :query, placeholder: "Search users" %>
  </div>
<% end %>

它在layouts/_header.html.erb内以<%= render "search" %>行呈现。

每执行一次搜索，都会得到以下控制台输出：

Started GET "/search?utf8=%E2%9C%93&query=hello" for 127.0.0.1 at 2018-06-21 18:37:20 -0400

页面似乎正在渲染，但是我的浏览器没有任何显示。为什么是这样？当前view/search/show.html.erb仅包含Rails生成的默认文本。

Answer 1

因为它是作为JS呈现/响应的。

通过SearchController＃show以JS处理

您需要使用HTML进行响应，以便浏览器可以直接呈现，也可以使用一些前端JavaScript来处理响应。

为什么此形式的GET请求不会将浏览器发送到呈现的视图？
