为什么用户id=edit?这是我的哈希,如果有帮助的话:

{"utf8"=>"✓",
 "_method"=>"put",
 "authenticity_token"=>"7g1WsNCVuNY/5ZTeBUdv97tbdAPacvvDAzBSMGCcuNY=",
 "user"=>{"email"=>"email@admin.com",
 "teacher"=>"Demont",
 "password"=>"[FILTERED]",
 "password_confirmation"=>"[FILTERED]",
 "current_password"=>"[FILTERED]"},
 "commit"=>"Update",
 "id"=>"edit",
 "format"=>"user"}

添加
userscocontroller
时,您的路由很可能发生冲突

这是无法解释的

编辑用户的默认设备路径为
/users/edit
,但在控制器中,更新操作的路径为
/users/:id
。为什么您使用“编辑”而不是
用户id

尝试使用:

@user = current_user
您的路线或编辑表单似乎有问题。尝试在他们的wiki页面中使用类似的表单。。。

但是上面的代码应该绕过这个使用

<%= form_for(@resource, :as => resource_name, :url => edit_user_registration_path(resource_name), :html => { :method => :put }) do |f| %>

在您的编辑操作中。

您可以发布编辑操作的代码吗?我添加了
edit
操作。现在已经很晚了,所以我会尝试在早上用大家的回答来解决这个问题,并标出最适合我的答案。谢谢大家!你可能是对的,我的路线上可能有一个更大的问题。但是现在使用
current_user
而不是
params[:id]
对我来说很有效。感谢所有其他人,我相信这些都是正确的答案。
@resource = User.find(params[:id])
