Question

您好我正在从Rails Book做教程并遇到一些麻烦。

我尝试使用我的用户名和密码登录时遇到以下错误：

路由错误

没有路线匹配[POST]“/ sessions / new” 尝试运行rake路线以获取有关可用路线的更多信息。

这是我的路线文件配置。

ZomfgShop::Application.routes.draw do
  get "admin/index"
  get "sessions/new"
  get "sessions/create"
  get "sessions/destroy"

  resources :users
  resources :orders
  resources :line_items
  resources :carts

  get "store/index"

  resources :products do
    get :who_bought, on: :member
  end

  resources :products

  root to: 'store#index', as: 'store'

  resources :line_items do
    #member do
    # post 'decrement'
    #end
    post 'decrement', on: :member
  end

  get 'admin' => 'admin#index'

  controller :sessions do
    get 'login' => :new
    post 'login' => :create
    delete 'logout' => :destroy
  end

Answer 1

对于：sessions路由，您有控制器而不是资源。

  resources :sessions do
    get 'login' => :new
    post 'login' => :create
    delete 'logout' => :destroy
  end

Answer 2

尝试替换

get "sessions/new"

get "sessions/create"

get "sessions/destroy"

与

resources :sessions

确保您有一个views / sessions / new.html.erb文件（在views / devise /下使用设计）

如果你没有使用Devise

，请确保你在sessions_controller.rb中有这个

def new
end
def create
end
def destroy
end

Answer 3

谢谢大家，将我的routes.rb文件更改为此，我的路由再次正常工作！

ZomfgShop::Application.routes.draw do
  get 'admin' => 'admin#index'

  controller :sessions do
    get 'login' => :new
    post 'login' => :create
    delete 'logout' => :destroy
  end
  scope '(:locale)' do
    resources :users
    resources :orders
    resources :line_items
    resources :carts
    get "store/index"
    resources :products do
      get :who_bought, on: :member
    end
  root to: 'store#index', as: 'store'
end

resources :line_items do
  #member do
  # post 'decrement'
  #end
  post 'decrement', on: :member
end

Rails路由错误。没有路线匹配[POST]“/ sessions / new”
