Answer 1

ArgumentError: Missing :controller key

用于将路由映射到 Controller 操作的符号是controller#action，而不是controller/action。相应地改变你的路线

Rails.application.routes.draw do

  resources :items

  root 'items#index'

  get 'items/index', to:'items#index'
  get 'items/show', to:'items#show'
  get 'items/new', to:'items#new'
  get 'items/edit', to:'items#edit'
  post '/items/create', to:'items#create'
  post '/items/update', to:'items#update'
  post '/items/destroy', to:'items#destroy'
  get '/users/userindex', to: 'users#userindex'
  get '/users/usershow', to: 'users#usershow'
  get '/users/usernew', to: 'users#usernew'
end

另外，你应该看看Resourceful Routing .您错误地声明了大部分路线。换句话说，当您已经通过 resources

获得它们时，就不需要它们了
