It looks as though using Release Phase commands (available as of 2 June 2016) is the preferred way of running things like migrations after the slug has been compiled and deployed.

The Buildpack API explicitly suggests avoiding side effects during the build:

Buildpack developers should avoid generating side effects during the build. For example, it is not recommended to perform database migrations in the compile script.

The following example creates a Rails app with a single migration and demonstrates that the migration is run after deployment.

# Create empty Rails app

	# config/deploy.rb

	require 'mina/bundler'
	require 'mina/rails'
	require 'mina/git'
	require 'mina/rvm'

	# ter_mode 这个要设置，不然在 mac 下输密码有问题
	set :term_mode, nil
	set :rvm_path, '/usr/local/rvm/bin/rvm'

	require 'mina/bundler'
	require 'mina/rails'
	require 'mina/git'
	require 'mina/rvm' # for rvm support. (http://rvm.io)

	set :domain, 'deploy@host'
	set :repository, 'git...
	set :branch, 'master'

	set :shared_paths, ['config/database.yml', 'config/application.yml', 'log', 'tmp/sockets', 'tmp/pids']

	class UsersController < ApplicationController


	def new
	@user = UserInformation.new
	end

	def index
	@users = UserInformation.all
	end
