我得到了这个奇怪的错误我假设这来自我的应用程序的routes.rb部分。我试图让用户在进入表单时成为一名修改者。一个用户只能成为一个修改者，因此has_one reviser user.rb模型上的Rails.application.routes.draw do
root 'pages#home'
devise_for :users ,
:path => '' ,
:path_names => { :sign_in => 'login', :sign_out => 'logout', :edit => 'profile' },
:controllers => { :omniauth_callbacks => 'omniauth_callbacks',
:registrations => 'registrations'
}
resources :users, only: [:index, :show] do
resource :reviser
end
谢谢！
routes.rb中：
class RevisersController < ApplicationController
before_action :set_reviser, only: [:show, :edit, :update]
before_action :authenticate_user!, except: [:show]
def index
@reviser = current_user.reviser
end
def show
end
def new
@reviser = current_user.build_reviser(params[:reviser])
@user = User.find(params[:user_id])
end
def create
@reviser = current_user.reviser.build(reviser_params)
if @reviser.save
redirect_to @reviser,notice: "saved...."
else
render :new
end
end
def edit
set_reviser
end
def update
set_reviser
if @reviser.update(reviser_params)
redirect_to @reviser, notice: "updated.."
else
render :edit
end
end
private
def set_reviser
@reviser = Reviser.find(params[:id])
end
def reviser_params
params.require(:reviser).permit(:description, :average_start, :average_end, :max_pages, :price_per, :active)
end
end

答案 0 :(得分：2)
您的:reviser路线有一个单一的资源定义。这对于您尝试执行的操作很有意义，但form_for [current_user, @reviser]生成的路线会尝试生成包含:user_id和:id的路线来识别您的审校。
因此，:id字段未在您的案例中定义，因为resource :reviser未创建:id。
解决方案是明确将form_for中的网址设置为您想要的路线：
它应该是：
form_for @reviser, url: edit_user_reviser_path(user_id: current_user.id)
您的代码存在的更大问题是您仍然在控制器中直接引用id的审核程序。在您当前的路由设置下，这将在Reviser.find()方法上返回错误。然而，更重要的是，这提出了一个安全问题，因为恶意用户可以在PATCH请求中发送id param来劫持和更新属于另一个用户的记录。
一个简单的解决方案是直接在current_user上引用reviser对象。
def set_reviser
@reviser = current_user.reviser
end
