Rails 3到4错误数目的参数错误为空散列参数

Question

我在更改参数后，我切换到强参数问题。我得到一个错误的号码参数错误的，这里的痕迹：

有人可以通过这个看看，并告诉我究竟是哪里出了问题？这是Rails 4中的语法错误吗？

Answer 1

如果user.rb线347是这一行：

assign_attributes(attributes, options) 

再有就是你的问题。 ActiveRecord#assign_attributes似乎只有一个参数Rails中4 See docs here

的Rails 3的API的方法，并允许options哈希值。 See docs here.

在rails 3中，options似乎已经处理访问控制，允许配置谁能够进行批量分配。在带有强烈参数的rails 4中，该责任已转移到param hash本身。

钢轨4个文档状态：

如果通过哈希响应permitted?方法，并且此方法的返回值是false一个ActiveModel::ForbiddenAttributesError异常。

总之，当你得到一个消息，告诉你，你是不是传递正确的参数的方法，你要做的第一件事应该是查找该方法的文档，看看如何你应该使用它。

当我读到这个问题时，我不知道答案是什么。我刚刚发现了将两个参数传递给您的代码的方法，然后查找了文档，答案非常清晰。
