当我尝试使用 mysql 数据库将 spree 安装到新的 rails 项目时出现以下错误。安装 spree 我得到以下错误，我不是 100% 如何解决它：

我的数据库yaml文件如下：-

development:
adapter: mysql2
encoding: utf8
reconnect: false
database: blind_development
pool: 5
username: root
password:
socket: /tmp/mysql.sock


test:
adapter: mysql2
encoding: utf8
reconnect: false
database: blind_test
pool: 5
username: root
password:
socket: /tmp/mysql.sock

production:
adapter: mysql2
encoding: utf8
reconnect: false
database: blind_production
pool: 5
username: root
password:
socket: /tmp/mysql.sock

在使用delayed_job时遇到了同样的问题，还没有找到解决方法。

编辑：我的问题是当我尝试使用它时，我认为活动记录尚未完全设置。当我通过我需要运行到 application.rb 中的 config.after_initialize 的块时，问题就消失了。
