How To Embed Documents In WordPress Blog Post

It’d be nice if we could integrate or embed documents within blog post on WordPress. Wouldn’t it be cool? I have seen that most bloggers create downloadable hyperlinks of the documents instead of embeds which force readers to download every time to read the documents. But if you can embed documents in your WordPress blog post, then you should do that. Because by embedding documents in your blog…

Fala galera! Precisei recentemente fazer um ordenação de um documento embutido no mongodb utilizando a gem mongoid. 

Imagine a estrutura a seguir:

user.rb

class User include Mongoid::Document field :name, :type => String, :index => true embeds_many :lists end

list.rb

class List include Mongoid::Document field :name, :type => String, :index => true embedded_in :user embeds_many :items end

item.rb

class Item include Mongoid::Document field :name, :type => String, :index => true field :price, :type => Float embedded_in :list end

Agora a pergunta que não quer calar! Como consigo ordernar todos os itens de todas as listas de um usuário por um determinado atributo do item, por exemplo price?

Éis a solução!

user.rb

class User include Mongoid::Document field :name, :type => String, :index => true embeds_many :lists def items(sort="price", ord="asc") self.lists.map(&:items).flatten.sort do |x,y| if ord == "desc" y[sort] <=> x[sort] else x[sort] <=> y[sort] end end end end
