Question

我遇到一个错误，当我尝试调用函数finalized_request时，它会抛出一个错误，说“param丢失或值为空：finalizedeal”。由于我是新手，我无法弄清楚我做错了什么（我是ROR的新手）。

Request_controller.rb

        request[:tag_id].each do |t|

Answer 1

代码是抱怨的，因为您需要:finalizedeal参数（但显然您没有将其传递），只需将此.require(:finalizedeal)添加到此代码中：

def finalizedRequest_params
  params.require(:finalizedeal).permit(:title , :description)
end

因此，一种解决方案是简单地删除require部分。像这样：

params.permit(:title , :description)

#require source

确保存在参数。

参数缺失错误（rails）
