编辑:第一个迁移文件: http://pastebin.com/49aJe2wv它出错的表甚至还不存在。

测试数据库中没有表。

EDIT2:堆栈跟踪的详细信息工厂/综合:87

Factory.define :media, :class => Media do |m| #line 87 <----

Answer 1

这看起来像是您的工厂或 factory_girl/factory_girl_rails 的问题。

factory_girl_rails 在启动时加载你所有的工厂，我认为如果它们包括关联、验证等，然后调用 ActiveModel/ActiveRecord 来检查模型。当然，在这种情况下，他们发现没有要检查的数据库。

我有同样的问题，解决方案/解决方法是删除 gem 'factory_girl_rails' 并将其替换为普通的 'factory_girl'，然后在 spec_helper 中手动加载工厂:

require 'factory_girl'
FactoryGirl.find_definitions
