调用 redirect_to 并且似乎没有呈现任何新内容答案

【问题标题】：Calling redirect_to and seemingly nothing new is rendered调用 redirect_to 并且似乎没有呈现任何新内容
【发布时间】：2014-12-22 02:01:42
【问题描述】：

在一个控制器中调用redirect_to controller: 'messages', action: 'index'。

在消息控制器中这样定义索引：

def index
  respond_to do |format|
    format.json { render :json => Message.all }
    format.html { }
  end
end

但是，在浏览器级别似乎没有任何内容被重定向，即 /messages 未显示。

想法？

end

重定向的来源：

def create
  @user = User.new(handle: params['name'], phone_number: params['phone_number'])
  if @user.save
      #render :json => [ @photo.to_jq_upload].to_json
      session[:user_id] = @user.id
      redirect_to controller: 'messages', action: 'index'
  else 
      #render :json => [{ :error => "An error was encountered while processing your photos. Please try again." }], :status => 304
  end
end

【问题讨论】：

发布 rails 日志和其他控制器源代码。
@MaurícioLinhares 已发布！想法？
日志显示重定向清楚地发生了，那之后不是还有另一个请求吗？
创建用户后在浏览器上看到什么URL？
@MaurícioLinhares 同意了，我猜也许不会，但我猜也许应该有？（另外，刚刚发布了重定向的代码！）

【解决方案1】：

您使用了 redirect_to 操作：“course_page1”、格式：“html”和返回这是不对的。如果它是一个重定向将工作正常 html请求但不是ajax。因此，如果您想重定向，尽管事实上该请求是一个ajax，使用可能是这样的

format.js { 渲染 :js => "window.location.href = '#{course_page_path}'" }

Rails console shows view is rendered, but doesn't render in browser
