batch = [{:name => "mongodb"}, {:name => "mongoid"}]  
Article.collection.insert(batch)

@page_views << page_view.as_document

PageView.collection.insert(@page_views)

books = [{:name => "Harry Potter"}, {:name => "Night"}]  
Book.collection.insert_many(books)

NoMethodError: undefined method `insert' for # <Mongo::Collection:0x007fbdbc9b1cd0>
Did you mean?  insert_one
               insert_many
               inspect

# Insert the provided documents into the collection.

def insert_many(documents, options = {})
  inserts = documents.map{ |doc| { :insert_one => doc }}
  bulk_write(inserts, options)
