Question

Can anyone show me how to edit the following migration to change :phone integer to string?

class CreateContactInfos < ActiveRecord::Migration
  def change
    create_table :contact_infos do |t|
      t.integer :phone
      t.string :facebook
      t.references :user

      t.timestamps 
    end
    add_index :contact_infos, :user_id
  end
end

Thanks in advance!

I guess you already migrated the one you’re showing, so create another in which you’d put:

change_column :contact_infos, :phone, :string
