remove_column

🗑️ Remove a Column from a Table

When an attribute becomes obsolete, use remove_column to drop it. Rails will automatically reverse the operation when rolling back.

# Terminal command

class RemoveDescriptionFromProducts < ActiveRecord::Migration[6.1]
  def change
    remove_column :products, :description, :text
  end
