Javascript Rails:redirect_to:back即使显示正确的日志也不重定向

我的html

<div class="modal-body center">         
      <form method="post">
        <textarea ng-model = "post.review" rows="10" cols="50" name="review" placeholder="something thougtful and helpful" style = "color: red;" class="fsField fsRequired fsTextAreaMaxLength", maxlength = "116"></textarea>

        <input ng-model = "post.rating" type="integer" name="rating" placeholder="0-10" style="color: red;" class="fsField fsRequired fsTextAreaMaxLength", maxlength = "116">

        <button ng-click = "submitReview(product)" class="btn btn-success" type="submit">Submit</button>

      <div ng-show = "duplicate_status" class = "submitStatus">*You have already submitted review for this Product</div>
      <div ng-show = "success_status" class = "submitStatus">*Your Review is successfully submitted</div>    
 </div>

轨道控制器

def create
  if !current_user.present?
    redirect_to :controller => 'user_sessions', :action => 'create'
    return
  end
  if Review.where(:user_id => current_user.id, :product_id => params[:product_id]).first.present?      
   render plain: "duplicate"    
  end
  @review = Review.new(:review => params[:review],
                     :rating => params[:rating],
                     :product_id => params[:product_id],
                     :user_id => current_user.id,
                     :date => Time.now.to_date)   
  if @review.save        
    redirect_to :back             
  else
    redirect_to :back        
  end    
end

问题是，在成功操作时，即在

@review.save上，
重定向到：back
不会刷新页面。
这是尽管日志显示正确

问题是控制权被不必要地转移到
GET/“

我是否错过了
return
的技巧？
您的问题是，您只重定向javascript发出的XHR请求——显示给用户的页面不受影响

为了更详细地了解这一点，在提交表单时，您会触发一些代码。此代码向服务器发送HTTP post。服务器进行填充，然后重定向该请求。javascript在幕后遵循重定向，并加载新页面。所有这些都对用户隐藏，只影响javascript发出的HTTP请求，而不是主页本身

为了更改主页窗口，您必须使用window.location显式地告诉页面转到其他地方

例如：

$http.post("/products/#{product.id}/review/new",$scope.review).success((data) ->
    ...
    window.location = data.redirect_url

在控制器中：

render :json, {status: "duplicate", redirect_url: "/product/2"}

页面将不会刷新，因为您正在使用javascript发布评论，因此您需要返回一些响应以显示成功的操作，而不是使用重定向调用。@usmanali:我尝试过这样做，我使用了
呈现普通：“success”
而不是
重定向到：back
，并在javascript中使用did
$http.get（“/product>）/#{product.id}“
检查
if data=='success'
。但似乎不起作用如何使用
json
响应？类似于
render json:{success:true}
的操作现在也尝试了
json
。没有显示任何更改。
render :json, {status: "duplicate", redirect_url: "/product/2"}
