How to implement such nosql, mongodb, mongoid structure?

Question

ruby

Hello. Sketched such a database schema

{ 
 {
   "className": String,
   "classMethods": [{
       "methodName": String,
       "description": String,
       "exampleCode": String,
       "sourceCode" : String
     },
     {
       "methodName": String,
       "description": String,
       "exampleCode": String,
       "sourceCode" : String
     }]
 },
 {
   "anotherClassName": String,
   "anotherClassMethods": [{
         "methodName": String,
         "description": String,
         "exampleCode": String,
         "sourceCode" : String
       },
       {
         "methodName": String,
         "description": String,
         "exampleCode": String,
         "sourceCode" : String
       }]
 }
}

but I don’t understand at all how to implement it on mongoid, so that it also looks beautiful from the point of view of oop.
I had an idea to do something like this

class MyClass
    include Mongoid::Document
    field :name, type: String
    field :methods, type: Array
  end

but I don't think that's how it should work. Yes, and access to data in the array will then be problematic.
Please help me how to get out of this situation?
