Ruby on Rails 记录未更新

Question

我在我的项目中使用 devise，我想从我的管理面板更新其他人配置文件，因此只有具有管理员角色的用户才能访问它，由于此行为与默认设计非常不同，我决定创建一个单独的控制器，这样我就可以像普通记录一样操纵用户，但由于某种原因，当我更新用户时， 记录不会更新到数据库中。

这些是我的路线

  devise_for :users, controllers: { registrations: 'users/registrations' }
  root "users#index"
  post "users/:id" => "users#show"
  get "users/:id" => "users#show", as: :user
  patch "users/:id" => "users#show"
  resources :receipts
  resources :notes
  get "users/edit/:id" => "users#edit", as: :edit_user 

这是我的控制器

def edit
    @user = User.find(params[:id])
end
def update
    user = User.find(params[:id])
    user.update(user_update_params)
    redirect_to user
end
private
    def user_update_params
        params.require(:user).permit(:username, :names, :last_names, :guardian, :phone, :identification, :role)
    end
    def user_params
        if @user.debts.nil?
            params.require(:user).permit(:debts)
        else
            params.require(:user).permit(:add_debt)
        end
    end

这些是我的观点

<% end %>

因此，在阅读了我的堆栈跟踪后，它确实尝试制作补丁，但随后它说不允许使用参数，这很奇怪，因为我已经在我的user_update_params方法上允许它们。

这出现在我的踪迹上

那么，如果我的文件甚至按照控制器的预期重定向，为什么我的文件没有更新呢？

感谢您的阅读。

Answer 1

由于您正在使用 devise 我认为您需要像这样设置它：

before_action :configure_permitted_parameters
  protected
  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:account_update) << [:username, :names]
  end

确保控制器继承自 dexie：

class UsersController < Devise::RegistrationsController
