我的嵌套has_many的路由是：关联正确吗？

Question

我有一个带有三个主要模型的rails API应用程序：User，Article和Annotation（annotations =创建文章部分的注释）和两个支持连接模型：Article_View_History和Annotation_View_History

用户可以创建文章以及查看文章。 article_view_history表记录了哪个用户查看了哪篇文章。

用户可以在每篇文章下创建注释并查看它们。 annotation_view_history表跟踪哪个用户查看了哪个注释。

routes.rb文件中的内容是否正确？

User.rb

class User < ActiveRecord::Base
  has_many :articles
  has_many :viewed_articles, through: :article_view_histories
  has_many :article_view_histories

  has_many :annotations
  has_many :viewed_annotations, through: :annotation_view_histories
  has_many :annotation_view_histories
end

Annotation.rb

class Annotation < ActiveRecord::Base
  belongs_to :article

  belongs_to :user
  has_many :annotation_view_histories
  has_many :viewed_users, through: :annotation_view_histories
end

Article.rb

class Article < ActiveRecord::Base
  belongs_to :user
  has_many :article_view_histories
  has_many :viewed_users, through: :article_view_histories

  has_many :annotations
end

AnnotationViewHistory.rb

class AnnotationViewHistory < ActiveRecord::Base
  belongs_to :viewed_users, :class_name => "User", :foreign_key => :user_id
  belongs_to :viewed_annotations, :class_name => "Annotation", :foreign_key => :annotation_id
end

ArticleViewHistory.rb

class ArticleViewHistory < ActiveRecord::Base
  belongs_to :viewed_users, :class_name => "User", :foreign_key => :user_id
  belongs_to :viewed_articles, :class_name => "Article", :foreign_key => :article_id
end

的routes.rb

  devise_for :users, :skip => :sessions, controllers: {registrations: 'api/registrations', passwords: 'api/passwords', confirmations: 'api/confirmations'}, defaults: { format: :json }

  use_doorkeeper do
    skip_controllers :applications, :authorized_applications, :authorizations
  end

  namespace :api, defaults: { format: :json }, path: '/' do
    scope module: :v1, constraints: ApiConstraints.new(version: 1, default: true) do
      resource :users, only: [:show] do
        resource :articles do
          resource :annotations
        end
        resource :article_view_histories
        resource :annotation_view_histories
      end
    end

    match '*path', to: -> (env) {
    [400, { 'Content-Type' => 'application/json' },
      [{ status: 404, error: 'Route Not Found' }.to_json]]
      }, via: :all
  end
