Rails, model with column of integer array

I have added created new migration:

class AddColumnsToDiscipline < ActiveRecord::Migration
 def change
   add_column :disciplines, :days, :integer, array: true
 end
end

Then I have run migration.

In my seed.rb file I have added this

t.disciplines.create(name: Company.name, days: [1, 2, 3])

After when I run rake db:seed, When I run my rails console all created models days attribute has nil value. Whad did I miss?

try this with default option

add_column :disciplines, :days, :integer, array: true, default: []

in your migration file and then 

run rake db:seed

EDIT

Try as 

add_column :disciplines, :days, :integer, array: true, default: '{}'

and change create to create! 

t.disciplines.create!(name: Company.name, days: [1, 2, 3])

If you are using strong parameters have you permitted days in your controller
