在 UsersController#deactivate 中的 ActiveRecord::RecordNotFound（找不到具有 'id'= 的用户）

Question

使用我的 rails 应用程序，我可以成功地销毁、注册和登录用户，但我似乎可以停用它们。我每次都会收到此错误： ActiveRecord::RecordNotFound in UsersController#deactivate (Couldn't find User with 'id'=)

record = s.execute([id], self, connection).first
    unless record
      raise RecordNotFound, "Couldn't find #{name} with '#{primary_key}'=#{id}"
    end
    record
  rescue RangeError

这是用户控制器：

def deactivate
 user = User.find(params[:user_id])
  if current_user.admin?
  user.deactivate_account!
  redirect_to users_path 
  else
   redirect_to :back
 end
end

_user.html.erb 视图：

<li><%= gravatar_for user, size: 50 %>
<%= link_to user.name, user %>
<% if current_user.admin? && !current_user?(user) %>
<%= link_to "delete", user, method: :delete,
                              data: { confirm: "You sure?" } %>
<% end %>

<% if current_user.admin? && @user != current_user %>
<%=link_to "deactivate", deactivate_path(user_id: @user), method: :post, 
                                         data: { confirm: "Are you sure?"}%> 
<% end %>
</li>

和路线：

get 'password_resets/new'
get 'password_resets/edit'
root             'static_pages#home'
get 'help'    => 'static_pages#help'
get 'about'   => 'static_pages#about'
get 'contact' => 'static_pages#contact'
get 'signup'  => 'users#new'
get    'login'   => 'sessions#new'
post   'login'   => 'sessions#create'
delete 'logout'  => 'sessions#destroy'
resources :users
resources :account_activations, only: [:edit]
resources :password_resets,     only: [:new, :create, :edit, :update]
post '/deactivate', to: "users#deactivate"

日志是：

可能出了什么问题？我假设错误在控制器中。我正在关注 Michael Hartl 教程，因为我是初学者，但我也在尝试自己实现（比如这个）。

首先，您应该将此作为PUT 请求而不是POST，因为它正在更新用户记录。

以下是我为完成这项工作所做的更改：

在您的routes.rb 文件中修改了到PUT 的路由：

put 'deactivate/:id(.:format)', :to => 'users#deactivate', :as => :deactivate_user

您没有为您的用户模型实现 deactivate_account 方法。我这样做了。在您的用户模型中：

def deactivate_account
 update_attributes!(activated: false)
end

最后，像这样更改用户部分：

<%=link_to "Deactivate", deactivate_user_path(user), method: :put%>
