Problem with Filling Tables.

I have an application that has models for beer styles.

Every beer style will have a name and description. It will also contain
a list of beer models.

Every beer model will contain a name.

I want my application to fill in the list of styles with some default
data.

#Beer migration file:
class CreateBeers < ActiveRecord::Migration
  def change
    create_table :beers do |t|
      t.string :name
      t.references :style
      t.timestamps
    end
    add_index :beers, :style_id
  end
end

#Style migration file:
class CreateStyles < ActiveRecord::Migration
  def change
    create_table :styles do |t|
      t.string :name
      t.text :description
      t.timestamps
    end
  end
end

#Beer Model
class Beer < ActiveRecord::Base
  belongs_to :style
end

#Style Model
class Style < ActiveRecord::Base
  has_many :beers
  def self.makeStyles
    beer = Hash[:name => "individual beer"]
    beerArray = [beer]
    style = Hash[:beers => beerArray, :name => "beer style",
:description => "This is a beer style."]
    styleArray = [style]
    self.create_styles(styleArray)
  end

   def self.create_styles(list_styles)
     list_styles.each do |s|
       new_style = Style.create(name: s[:name], description:
s[:description])
       new_style.save
       list_styles[:beers].each do |b|
         new_style.beers.create(name: b[:name])
         new_style.beers.save
       end
     end
   end
end

The parts in comments is the code that was breaking the application.

When I ran rake db:seed on the code without the comments, I got the
following error message. Does anyone know what is going on?

...
    beer = Hash[:name => "individual beer"]

That should be beer = {:name => "individual beer"} or beer =
HASH["name", "individual beer"]
See http://www.ruby-doc.org/core-2.0.0/Hash.html#method-c-5B-5D

    style = Hash[:beers => beerArray, :name => "beer style",
:description => "This is a beer style."]

Same again
