change column name Rails

Question

I have this table:

class CreateShoes < ActiveRecord::Migration
  def change
    create_table :shoes do |t|
      t.string :name
      t.boolean :leather
              


        

Answer 1

Run in your console:

$ rails g migration rename_season_to_season_id

Now file db/migrate/TIMESTAMP_rename_season_to_season_id.rb contains following:

class RenameSeasonToSeasonId < ActiveRecord::Migration
  def change
  end
end

Modify it as follows:

class RenameSeasonToSeasonId < ActiveRecord::Migration
  def change
    rename_column :shoes, :season, :season_id
  end
end

Then run $ rake db:migrate in console.
