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

Either fix your migration and do

rake db:rollback db:migrate

or make another migration like so:

rename_column :shoes, :season, :season_id if column_exists?(:shoes, :season) && !column_exists?(:shoes, :season_id)

and then do

rake db:migrate
