我仍然是一个有点不懂铁路的人,但我遇到了一些似乎有点奇怪的事情。我向数据库中的模型添加了一个布尔字段
t.column :admin, :bool, :default => false, :null => false
但是,sqlite3数据库中的值似乎是
't'
或
'f'
user.admin?
如果值为,则返回false
“f”
>> user = User.first
=> #<User id: 2, login: "matt", name: "", email: "google.ninja@no-spam.com", crypt
ed_password: "c6740f820b4cbf6e3d88188719f23cd3053a54f0", salt: "5629f5ee09f51543
a7d64dd903b8d9e53aa43a24", created_at: "2009-04-26 23:08:05", updated_at: "2009-
04-26 23:10:38", remember_token: nil, remember_token_expires_at: nil, admin: "t"

这只是sqlite的一些奇怪问题,还是我没有得到什么?
