Question

我在TicketsController＃update中得到一个AbstractController :: DoubleRenderError。如果我选择特定用户，则不会进行更新。

def update

    @selected_group = Group.find_by_id(params[:Department]) unless params[:Department].nil?
    @selected_company = Company.find_by_id(params[:Company]) unless params[:Company].nil?
    @ticketnote_content = params[:Ticketnote] 

    if ((@selected_group != nil) && (@selected_company != nil))

      map_group_to_department
      map_user_to_staff
      update_ticket

      if (@response['response'] == "Failed")
        flash[:error] = response['err_desc']
        redirect_to "/ticket/#{params[:id]}/edit"
        return
      elsif (@response['response'] == "Success")
          @ticketnote_content
          if @ticketnote_content != ""
              add_note_to_ticket
         end
        map_assets_findings_tickets
        flash[:notice] = "Succesfully updated the ticket"
        TicketHistory.create_ticket_history(@assigned_user,@selected_asset,@ticket_params,current_user,@updated_ticket_response,"Updated")
      end
    else

      flash[:error] = "Company or department can't be blank."
      redirect_to "/ticket/#{params[:id]}/edit"
      return
    end
    redirect_to :controller => 'tickets' , :action => 'show', :id => params[:id],:test_id => @test,:ticket_id=> params[:ticket_id]
end

由于您已经在if else语句中使用了redirect_to，并且在执行if else之后再次重定向，导致此错误（您可以在每个操作中仅使用一次）。为了解决这个问题，我建议采用以下解决方案（问题不明确，所以我可能不对）：

解决方案1 ：如果您的上次redirect_to不是必需的，则将其删除，即

redirect_to :controller => 'tickets' , :action => 'show', :id => params[:id],:test_id => @test,:ticket_id=> params[:ticket_id]

解决方案2 ：在每个redirect_to中使用and return进行更新，并在成功的响应条件中移动您的最后一次redirect_to（我不确定您希望Ticket#show的位置），即

def update
  @selected_group = Group.find_by_id(params[:Department]) unless params[:Department].nil?
  @selected_company = Company.find_by_id(params[:Company]) unless params[:Company].nil?
  @ticketnote_content = params[:Ticketnote] 

  if @selected_group && @selected_company
    map_group_to_department
    map_user_to_staff
    update_ticket

    if (@response['response'] == "Failed")
      flash[:error] = response['err_desc']
      redirect_to "/ticket/#{params[:id]}/edit"
    elsif (@response['response'] == "Success")
      add_note_to_ticket if @ticketnote_content != ""
      map_assets_findings_tickets
      flash[:notice] = "Succesfully updated the ticket"
      TicketHistory.create_ticket_history(@assigned_user,@selected_asset,@ticket_params,current_user,@updated_ticket_response,"Updated")
      redirect_to :controller => 'tickets' , :action => 'show', :id => params[:id],:test_id => @test,:ticket_id=> params[:ticket_id]
    end
  else
    flash[:error] = "Company or department can't be blank."
    redirect_to "/ticket/#{params[:id]}/edit" and return
  end 
end

P.S。：您可以在一行中使用redirect_to和flash [：message]：

redirect_to your_path(params), :notice => "your message"
