请检查我的代码，让我知道我错误的地方和解决方案。
答案 0 :(得分：1)
调试参数错误时，您有两种可能的选择：
首先要做的是查看提供的堆栈跟踪。它会告诉你要看。最有可能的错误是在跟踪中给出的行或其正上方的行中的错误。在你的情况下它说：
app / controllers / homes_controller.rb：148：在`updatedata＆＃39;
这告诉你要查看：
controller：homes_controller.rb
行动：updatedata
确切行号：148
您的代码编辑器应该能够显示行号和/或跳转到特定的行号。如果仔细查看该位置，您将看到使用（）而不是[]的情况。我怀疑这会使系统混乱并导致参数错误。
此外，从轨道编码标准的角度来看，您应该将该控制器分解为多个控制器。通常，您应该只在控制器中执行索引，新建，创建，编辑，更新和删除操作。如果您发现自己制作了许多自定义命名操作，则表明您需要另一个控制器。
答案 1 :(得分：0)
params是一个哈希值，因此您必须将第148行编辑为：
if @users.update_attributes(params[:users])
