使用friendly_id 匹配单个Rails 路由中的多个模型

问题描述：

我有一个 Company 和一个 User 模型，两者都带有一个通过friendly_id 的 slug.确保两个模型中的 Slug 都是唯一的.

I have a Company and a User model, both with a slug via friendly_id. Slugs are ensured to be unique across both models.

我想要网址:

http://www.example.com/any_company_name

http://www.example.com/any_user_name

例如/apple 和 /tim

我不确定如何在 Rails 中实现这一点.

I'm not sure how to achieve this in Rails.

我尝试了以下各种排列:

I have tried various permutations of:

routes.rb:
  resources :users, path: ''
  resources :companies, path: ''
  get '*search', to: 'my_controller#redirect'

和

my_controller#redirect:
  @company = Company.friendly.find(params[:search])
  redirect_to @company if @company
  @user = User.friendly.find(params[:search])
  redirect_to @user if @user

但是我无法让它工作.我可以让 /apple 重定向到 /companies/apple 和 /tim 重定向到 /users/tim(通过删除 path: '' 选项)但这不是我想要实现的.

However I can't get it to work. I can get /apple to redirect to /companies/apple and /tim to redirect to /users/tim (by removing the path: '' option) but this is not what I want to achieve.

我遇到了类似的问题，并且能够通过创建具有 slug 属性和与Sluggable"类的多态关联的 PublicSlug 模型来解决它.我还使用了一个 Sluggable 问题，我将其包含在我想查询的模型中.

I had a similar problem and was able to solve it by creating a PublicSlug model with a slug attribute and a polymorphic association to a "Sluggable" class. I also used a Sluggable concern that I included in models I would like to query.

PublicSlug 模型

The PublicSlug model

class PublicSlug < ActiveRecord::Base
  extend FriendlyId

  friendly_id :sluggable_name, use: :slugged

  belongs_to :sluggable, polymorphic: true

  private

  # Generate the slug based on the title of the Sluggable class
  def sluggable_name
    sluggable.name
  end
end

懒惰的关注

module Sluggable
  extend ActiveSupport::Concern

  included do
   has_one :public_slug, dependent: :destroy, as: :sluggable

   delegate :slug, to: :public_slug
  end
end

公司和用户模型.

class User < ActiveRecord::Base
  include Sluggable
end

class Company < ActiveRecord::Base
  include Sluggable
end

我现在可以使用

Sluggable.friendly.find(slug).sluggable

重定向可以在您的控制器中处理如下:

The redirect could be handled in your controller as follows:

def redirect
  @sluggable = Sluggable.friendly.find(params[:search]).sluggable

  redirect_to @sluggable
end
