从什么时候开始 users 不是受支持的控制器名称？

Question

我在这里使用 rails 已经有一段时间了，这是我第一次运行遇到这个问题我在终端 '/users 的顶部收到这个错误' 不是受支持的控制器名称。这可能会导致潜在的路由问题。在尝试运行迁移以从 table.

中删除某些内容时，请参阅 https://guides.rubyonrails.org/routing.html#specifying-a-controller-to-use 以及其他一些内容

Rails.application.routes.draw do
  # For details on the DSL available within this file, see https://guides.rubyonrails.org/routing.html

  ### USERS ROUTES ###
  get "/users" => "/users#index"
  post "/users" => "/users#create"
  get "/users/:id" => "/users#show"
  patch "/users/:id" => "/users#update"
  delete "/users/:id" => "/users#destroy"

  ### ROLES ROUTES ###
  get "/roles" => "/roles#index"
  post "/roles" => "/roles#create"

  ### GROUPS ROUTES ###
  get "/groups" => "/groups#index"
  get "/groups/:id" => "/groups#show"
  patch "/groups/:id" => "/groups#update"
end

ActiveRecord::Schema.define(version: 2022_05_24_161744) do

  # These are extensions that must be enabled in order to support this database
  enable_extension "plpgsql"

  create_table "groups", force: :cascade do |t|
    t.string "name"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end

  create_table "roles", force: :cascade do |t|
    t.string "title"
    t.integer "user_id"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end

  create_table "users", force: :cascade do |t|
    t.string "first_name"
    t.string "last_name"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end

end

我的路线和我的架构设置与我一直以来的设置非常相似，我在终端中收到上面的错误我只是想从角色中删除 user_id 我遵循 link 和它给了我以前用来设置这些路线的所有东西。

问题出在路径映射中的 /。映射必须采用 Controller#Action 格式，如 Rails 指南中的 Ruby - https://guides.rubyonrails.org/routing.html#specifying-a-controller-to-use 中所指定。这也适用于其他路线，而不仅仅是用户。

解决方案：通过从映射中删除 / 来修改路由文件，如下所示

config/routes.rb

Rails.application.routes.draw do
  # For details on the DSL available within this file, see https://guides.rubyonrails.org/routing.html

  ### USERS ROUTES ###
  get "/users" => "users#index"
  post "/users" => "users#create"
  get "/users/:id" => "users#show"
  patch "/users/:id" => "users#update"
  delete "/users/:id" => "users#destroy"

  ### ROLES ROUTES ###
  get "/roles" => "roles#index"
  post "/roles" => "roles#create"

  ### GROUPS ROUTES ###
  get "/groups" => "groups#index"
  get "/groups/:id" => "groups#show"
  patch "/groups/:id" => "groups#update"
end
