Db 不播种：如何确定原因？

Question

None seeds.rb 中的数据被加载到开发数据库中。没有错误信息。我怎样才能确定原因？

如果我运行 rake:db:migrate:reset 它只是运行并且不会产生任何错误消息。如果我转到控制台运行 User.first，它会显示 nil。我还下载了开发数据库，但里面没有记录（表创建正确，只是没有记录）。

有什么方法可以追查原因吗？ seeds.rb的一部分：

User.create!(fullname:  "Example User",
                    username: "fakename0",
                    email: "example@railstutorial.org",

要加载 db/seeds.rb，您需要运行 rake db:seed.
