任何人都知道在尝试序列化ActiveJob::SerializationError
或Date
对象时避免出现Time
的干净方法吗?
到目前为止,我已经解决了两个问题:
dump
,然后在作业中调用load
(这很糟糕,因为我需要修补邮件工作)Date
和Time
之类似:/lib/core_ext/time.rb
class Time
include GlobalID::Identification
def id
self.to_i
end
def self.find(id)
self.at(id.to_i)
end
end
/lib/core_ext/date.rb
class Date
include GlobalID::Identification
def id
self.to_time.id
end
def self.find(id)
Time.find(id).to_date
end
end
哪个也很糟糕。任何人都有更好的解决方案吗?

你真的需要序列化吗?如果它只是一个Time / DateTime对象,为什么不编码并将参数作为Unix时间戳原语发送?
>> tick = Time.now
=> 2016-03-30 01:19:52 -0400
>> tick_unix = tick.to_i
=> 1459315192
# Send tick_unix as the param...
>> tock = Time.at(tick_unix)
=> 2016-03-30 01:19:52 -0400
请注意,这将精确到一秒钟内。如果您需要100%准确的准确度,您需要将时间转换为Rational并将分子和分母作为参数传递,然后在作业中调用Time.at(Rational(numerator, denominator)
。
>> tick = Time.now
=> 2016-03-30 01:39:10 -0400
>> tick_rational = tick.to_r
=> (1459316350224979/1000000)
>> numerator_param = tick_rational.numerator
=> 1459316350224979
>> denominator_param = tick_rational.denominator
=> 1000000
# On the other side of the pipe...
>> tock = Time.at(Rational(numerator_param, denominator_param))
=> 2016-03-30 01:39:10 -0400
>> tick == tock
=> true
