Rails - Add serialize Array to existing model

I am trying to add an array to my model "User"

serialize :year, Array

How do I add this attribute to my model? I see most places saying to just write this into the Users.rb file, but then there is never a column. Am I missing something?

Also, How do I access it from my controller? Thanks

You must have a column in your database. Then serialize the object and no need to mention the type of the object, if you are not sure. It is as follows :

    serialize :year

If you assign hash it will be hash object or you assign array it will be Array object.

You have to add the column year to database as text column

add_column :users, :year, :text

You can access it like normal array.

Eg:

user = User.new(:year => ["2012", "8", "22"])

user.year #=> ["2012", "8", "22"]
