我因以下错误而发疯。我有一个 User 类,它的两个属性(生日和 created_at => 日期时间)总是返回 nil,除了它在数据库上有一个值。

我正在使用设计来管理身份验证。

这是数据库表:

CREATE TABLE users
(
id serial NOT NULL,
email character varying(255) NOT NULL DEFAULT ''::character varying,
encrypted_password character varying(255) NOT NULL DEFAULT ''::character varying,
reset_password_token character varying(255),
reset_password_sent_at timestamp without time zone,
remember_created_at timestamp without time zone,
sign_in_count integer NOT NULL DEFAULT 0,
current_sign_in_at timestamp without time zone,
last_sign_in_at timestamp without time zone,
current_sign_in_ip character varying(255),
last_sign_in_ip character varying(255),
name character varying(255),
lastname character varying(255),
birthday timestamp without time zone,
gender character varying(255),
created_at timestamp without time zone,
updated_at timestamp without time zone,
authentication_token character varying(255),
facebook_uid character varying(255),
gplus_uid character varying(255),
CONSTRAINT users_pkey PRIMARY KEY (id)
)
WITH (
OIDS=FALSE
);

这是模型
#encoding: utf-8
class User < ActiveRecord::Base

has_many :user_benefits
has_many :benefits, through: :user_benefits

devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable

validates :gender, :inclusion => { :in => %w(m f)}
validates :email, email_format: { message: "Email invalido" }

before_save :ensure_authentication_token

def ensure_authentication_token
if authentication_token.blank?
self.authentication_token = generate_authentication_token
end
end

def set_gender new_gender

case new_gender.downcase
when "male"
self.gender = 'm'
when "female"
self.gender = 'f'
when "m"
self.gender = 'm'
when "f"
self.gender = 'f'
else
self.gender = nil
end

end

def get_response
{
:auth_token=>self.authentication_token,
:user => {
:email=> self.email,
:name=> self.name,
:lastname=> self.lastname,
:birthday=> self.birthday,
:gender=> self.gender,
:auth_token=> self.authentication_token,
:created_at=> self.created_at,
:updated_at=> self.updated_at,
:facebook_uid=> self.facebook_uid,
:gplus_uid=> self.gplus_uid
}
}
end

private

def generate_authentication_token
loop do
token = Devise.friendly_token
break token unless User.where(authentication_token: token).first
end
end

end

当我调用 get_response 我得到:
{
auth_token: "fRoi1RPTuP64m55jXCSS"
user: {
email: "testg@habitues.com"
name: "Lalo"
lastname: "Landa"
birthday: null
gender: "m"
auth_token: "fRoi1RPTuP64m55jXCSS"
created_at: null
updated_at: "2013-11-27T20:14:22.534-03:00"
facebook_uid: null
gplus_uid: null
}
new: false
}

有人有想法吗?

谢谢

最佳答案

config.active_record.default_timezone 需要一个符号,可以是 :local 或 :utc。
config.time_zone 需要一个常规的时区,就像你所做的那样。
config.active_record.default_timezone 确定从数据库中提取日期和时间时是使用 Time.local(如果设置为 :local)还是 Time.utc(如果设置为 :utc)。默认为:utc。
