我为用户模型的show动作设计了一个用户控制器。 路线设置如下;
Rails.application.routes.draw do
resources :docs
resources :documents, only: [:new, :create, :index]
#get 'users/show'
devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)
devise_for :users
resources :users, only: [:show]
#resources :users do
resources :personal_accounts,path: "user_account", only: [:show] do
resources :deposits, only: [:new, :show, :create, :index]
resources :withdraws, only: [:new, :show, :create, :index]
end
resources :businesses do
resources :business_accounts, path: "business_account", only: [:show] do
resources :business_withdraws, only: [:new, :show, :create, :index]
resources :business_deposits, only: [:new, :show, :create, :index]
end
end
#end
devise_scope :user do
authenticated :user do
root :to => 'dashboard#index'
end
unauthenticated :user do
root :to => 'devise/registrations#new', as: :unauthenticated_root
end
end
namespace :api do
namespace :v1, defaults: {format: :json} do
resources :payments
resources :withdraws
resources :balances
end
end
end
然而，路线http://localhost:3000/users/1工作得很好，但路线http://localhost:3000/documents/new不起作用并引发错误没有路线匹配{：action =＆gt;＆＃34; show＆＃34;， ：controller =＆gt;＆＃34;用户＆＃34;，：id =＆gt; nil}缺少必需的密钥：[：id]
