我的应用程序基本上由一个用户参加课程，并通过各种步骤来完成课程。但是，我认为我的路由存在问题。现在这里是路线 1 > 级别 1 > 步骤 1 的路线
http://localhost:3000/courses/1/levels/1/steps/1
这是课程 2 > 级别 1（当然是 2）> 步骤 1（当然是 2）的路线：
http://localhost:3000/courses/2/levels/4/steps/10
它需要步骤和级别的文字 ID。实际上，我认为如果上述路线说：
http://localhost:3000/courses/2/levels/1/steps/1
甚至
http://localhost:3000/course_title/levels/1/steps/1
我将如何实现这一点，路由是否有意义？
路由.rb
Serenity::Application.routes.draw do
root to: 'static_pages#home'
match '/help', to: 'static_pages#help'
match '/about', to: 'static_pages#about'
match '/contact', to: 'static_pages#contact'
devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)
devise_for :users
ActiveAdmin.routes(self)
resources :users do
member do
get :courses
end
end
resources :courses do
resources :levels, only: [:show] do
resources :steps, only: [:show]
end
end
resources :assignments, only: [:create, :destroy]
end
简而言之，这是我的模型：用户通过分配模型学习课程，每个课程都有级别和步骤。
class User < ActiveRecord::Base
has_many :assignments, dependent: :destroy
has_many :courses, through: :assignments
class Assignment < ActiveRecord::Base
attr_accessible :course_id
belongs_to :user
belongs_to :course
class Course < ActiveRecord::Base
has_many :assignments
has_many :users, through: :assignments
has_many :levels
class Level < ActiveRecord::Base
belongs_to :course
class Step < ActiveRecord::Base
belongs_to :level
