 , :string, default: [], array: true first change column_type to string from integer   1. add new migration    2. add condition in migration  class AddExecuteOnToApprovals < ActiveRecord::Migration[6.0]   def change     unless ActiveRecord::Base.connection.column_exists?(:approvals, :execute_on)       add_column :approvals, :execute_on, :string, default: [], array: true     end   end end 3. set enum in model for string with add_array condition ::  self.table_name = :approvals # enum execute_on: [:record_creation, :record_edit] enum status: [:approved, :not_approved] enum execute_on: { "record_creation" => "record_creation", "record_edit" => "record_edit" }

  class ChangePhoneToBeStringInCustomers < ActiveRecord :: Migration [ 5.0 ] def up change_column :customers , :phone , :string end def down change_column :customers , :phone , :integer end end The code we need to add takes the form of change_column :table_name , :column_name , :new_type In our case it would be something like change_column :customers , :phone , :string The completed file will look like this class ChangePhoneToBeStringInCustomers < ActiveRecord :: Migration [ 5.0 ] def change change_column :customers , :phone , :string end end
