使用多個文件上傳時刪除單個文件Carrierwave

我已經在部分this教程中指出，在使用Carrierwave上傳多個文件時刪除單個文件。刪除單個圖像可以正常工作，但在瀏覽器控制檯和Rails服務器輸出中出現錯誤。我的代碼：使用多個文件上傳時刪除單個文件Carrierwave

控制器：

def destroy 
    if params[:index] 
    remove_image_at_index(params[:index].to_i) 
    redirect_to :back 
    else 
    authorize @job 
    @job.destroy 
    respond_to do |format| 
     format.html { redirect_to real_property_sales_url } 
    end 
    end 
end 

def remove_image_at_index(index) 
    remain_images = @job.photos 
    deleted_image = remain_images.delete_at(index) 
    deleted_image.try(:remove!) 
    @job.photos = remain_images 
end

路線：

resources :real_property_sales

LINK_TO：

<%= link_to real_property_sale_path(@job, index: index), method: :delete, data: { confirm: 'Are you sure?' }, :remote => true do %> 
    <span class="fa-stack fa-lg"> 
    <i class="fa fa-circle-o fa-stack-2x"></i> 
    <i class="fa fa-times fa-stack-1x"></i> 
    </span> 
<% end %>

服務器輸出：

我解決了這個用head :no_content：

def destroy 
    if params[:index] 
    remove_image_at_index(params[:index].to_i) 
    head :no_content 
    else 
    authorize @job 
    @job.destroy 
    respond_to do |format| 
     format.html { redirect_to real_property_sales_url } 
    end 
    end 
end
