從mongoid標準

Question

irb(main):019:0> a = Admin.first 
=> #<Admin _id: 514b318da61654dd05000002, email: "email@email.com", encrypted_password: "$2a$10$b.cWtfPNgUcCubJRX2vjAO6vEsds9OTGO2tn6Lfz2cBU.mwTYsHw."> 

irb(main):020:0> a.class.name 
=> "Admin" 

irb(main):021:0> a = Admin.all 
=> #<Mongoid::Criteria 
    selector: {} 
    options: {} 
    class: Admin 
    embedded: false> 

irb(main):022:0> a.class.name 
=> "Mongoid::Criteria" 

我如何得到型號名稱內「Mongoid ::標準」類得到的類名？

謝謝！

你可以用這個做到這一點：

a.klass #=> Admin 
or 
a.klass.name #=> "Admin"
