Rails虚荣URL阻止#edit工作

Question

用户可以创建和编辑故事（主要是博客）。我为故事设置了一个自定义虚荣心 URL，因此它不仅显示递增的 ID，还显示 /stories/1-some-story-title。这对 #show 很有效，但是当我尝试编辑故事时，（使用 /stories/1-some-story-title/edit 路由）我看到一个错误：

Routing Error:
No route matches [POST] "/stories/1-some-story-title/edit"

但是，如果我尝试手动访问非虚荣 URL (/stories/1/edit) 它会起作用，所以这绝对是虚荣 URL 没有在数据库中查找的问题正确的，我只是还没有弄清楚为什么。

我觉得很奇怪 Rails 可以毫无问题地为 #show 查找故事，但遇到 #edit

的问题

值得注意的是，我正在使用 Active Admin 和 Action Text (Trix)。

感谢任何指导。我仍然掌握着 Rails 的诀窍，所以任何您认为有帮助的文章当然也欢迎。

故事控制器#show、#edit 和#update

  def show
    @story = Story.find(params[:id])
  end

  def edit
    @story = Story.find(params[:id])
    unless @current_user.is_admin?
      redirect_to root_path if @story.created_at < 2.hours.ago
      redirect_to root_path unless @current_user == @story.user
    end
  end

  def update
    @story = Story.find(params[:id])
    if @story.user == @current_user || @current_user.is_admin?
      if @story.update(form_params)
        redirect_to story_path(@story)
      else
        render 'edit'
      end
    else
      redirect_to root_path
    end
  end

models/story.rb

class Story < ApplicationRecord


  # A story can have many comments
  has_many :comments, dependent: :destroy
  # A story can have many favourites
  has_many :favourites, dependent: :destroy
  # A story can only belong to one user
  belongs_to :user

  # Add Trix Rich Text Editor
  has_rich_text :body

  # Add image uploader
  mount_uploader :image, ImageUploader

  validates :title, presence: true
  validates :body, presence: true, length: { minimum: 10 }

  # Changing story URL from number to story title
  def to_param
    id.to_s + '-' + title.parameterize
  end

end

Routes.rb

Rails.application.routes.draw do
  ActiveAdmin.routes(self)

  # Routes for stories
  resources :stories do
    resources :comments
    resource :favourite
  end

  # routes for users
  resources :users
  # Routes for sessions
  resource :session

  # Set homepage as stories index page
  root 'stories#index'

  # Add new pages and their urls
  get 'about', to: 'pages#about'
  get 'our-story', to: 'pages#our_story'

  get 'favourites', to: 'favourites#index'

Answer 1

已修复。需要添加：

  def to_param
    id.to_s + '-' + title.parameterize
  end

到 app/admin/stories.rb 文件。它已包含在 story.rb 模型中，但不在 Active Admin 的目录中。
