ruby - how (replace|create) an enum field on rails 2.0 migrations?

Question

I would like to create an enum field at sone migration I'm doing, I tried searching in google but I can't find the way to do it in the migration

the only thing I found was

  t.column :status, :enum, :limit => [:accepted, :cancelled, :pending]

but looks like the above code runs only on rails 1.xxx and since I'm running rails 2.0

this what I tried but it fails

class CreatePayments < ActiveRecord::Migration
  def self.up
    create_table :payments do |t|
      t.string :concept
      t.integer :user_id
      t.text :notes
      t.enum :status, :limit => [:accepted, :cancelled, :pending]

      t.timestamps
    end
  end

  def self.down
    drop_table :payments
  end
end

So, in case that isn't allowed, what do you think could be a good solution? just a text field, and validating from the model?

Answer 1

You can manually specify the type by using the t.column method instead. Rails will interpret this as a string column, and you can simply add a validator to the model like Pavel suggested:

class CreatePayments < ActiveRecord::Migration
  def self.up
    create_table :payments do |t|
      t.string :concept
      t.integer :user_id
      t.text :notes
      t.column :status, "ENUM('accepted', 'cancelled', 'pending')"

      t.timestamps
    end    
  end

  def self.down
    drop_table :payments
  end
end

class Payment < ActiveRecord::Base
  validates_inclusion_of :status, :in => %w(accepted cancelled pending)
end
