我在使用Heroku.com服务发布我的ROR项目时遇到问题... 我已完成此tutrial
的所有步骤但是当我在运行命令“heroku open”时，我有一个错误“我们很抱歉，但出了问题”，那么我做错了什么？
我已经迁移了数据库，但我认为这个错误与数据库连接，这里是heroku日志：

我被这篇帖子评为Ruby on Rails App deployed to heroku showing "We're sorry, but something went wrong"，但就我而言，这对我没有帮助=（ 那么有人可以帮我解决我的问题吗？
UPD 1： 这是create_cart_items.rb代码：
class CreateCartItems < ActiveRecord::Migration
def change
create_table :cart_items do |t|
t.column :book_id, :integer
t.column :cart_id, :integer
t.column :price, :float
t.column :amount, :integer
t.column :created_at, :datetime
end
end
end
UPD 2 ：这是db：migrate trace：
Running `rake db:migrate --trace` attached to terminal... up, run.7697
