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

If your branch has been pushed to production then one probably needs to add the new migration by running the following command:

rails g migration RenameSeasonColumnNameToShoes

and if it hasn't been pushed to production or you have to currently make changes to your branch only, then do:

bundle exec rake db:rollback

Then make changes to your migration file inside /db/migrate/

Then in your migration file, using rename_column do as follows:

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

and then do

bundle exec rake db:migrate db:test:prepare
