Mongoid恢复失败

我在mongoid中有一个验证，如果它在保存错误信息时失败了，我想恢复它。Mongoid恢复失败

例

if @thing.update_attributes(params[:thing]) 
    format.html { redirect_to @thing, notice: 'Thing was successfully updated.' } 
    format.json { head :no_content } 
else 
    #revert the fields that have changed and keep @thing.errors 
    format.html { render action: "edit" } 
    format.json { render json: @thing.errors, status: :unprocessable_entity } 
end

当我保存关闭文档，然后重新插入，它似乎不想分配@thing.errors = errors

感谢
