序列化日期属性 [英] serialize date attributes

问题描述

我正在使用active_model_serializers和ember.js。我的一个模型有一个日期属性。在rails日期属性按YYYY-MM-DD的格式进行序列化。

问题;当ember数据使用javascript Date构造函数取消序列化日期时，它假定不正确的时区。

*不正确不是最好的单词，但它是不正确的，因为我希望它默认为当前时区。 DS.Model date属性解析日期（YYYY-MM- DD）不正确

我认为active_model_serializer应该采用date属性并将其转换为iso8601格式。

  Object.date.to_time_in_current_zone.iso8601 
  

是有办法告诉active_model_serializers如何序列化所有的日期对象？或者我应该在javascript中修复时区问题？

解决方案

这是我目前的解决方案，但我真的觉得应该可以定义日期对象如何在全局序列化。

  class InvoiceSerializer< ActiveModel :: Serializer 
属性：id，：customer_id，：balance 
 
定义属性
哈希=超级
哈希['日期'] = object.date.to_time_in_current_zone .iso8601如果object.date 
哈希
结束
结束
  

更新

我现在的首选解决方案是将猴子补丁到$ code> ActiveSupport :: TimeWithZone.as_json 方法。

 ＃config / initializers / time.rb 
模块ActiveSupport 
类TimeWithZone 
 def as_json（options = nil ）
 time.iso8601 
 end 
 end 
 end 
 
 class InvoiceSerializer< ActiveModel :: Serializer 
属性：id，：customer_id，：balance，：date 
 end 
  

I am using active_model_serializers and ember.js. One of my models has a date attribute. In rails date attributes are serialized in the format of "YYYY-MM-DD".

The problem; when ember-data de-serializes the date using the javascript Date constructor it assumes an "incorrect" timezone.

*Incorrect is not the best word but it is incorrect because I want it to default to the current timezone. DS.Model date attribute parses date (YYYY-MM-DD) incorrectly

I am thinking the active_model_serializer should take the date attribute and convert it to iso8601 format.

 Object.date.to_time_in_current_zone.iso8601

Is there a way to tell active_model_serializers how to serialize all date objects? Or should I be fixing the timezone issue in javascript?

解决方案

Here is my current solution but I really feel it should be possible to define how date objects get serialized globally.

class InvoiceSerializer < ActiveModel::Serializer
  attributes :id, :customer_id, :balance

  def attributes
    hash = super
    hash['date'] = object.date.to_time_in_current_zone.iso8601 if object.date
    hash
  end
end

UPDATE

My preferred solution now is to monkey patch the ActiveSupport::TimeWithZone.as_json method.

#config/initializers/time.rb
module ActiveSupport
  class TimeWithZone
    def as_json(options = nil)
      time.iso8601
    end
  end
end

class InvoiceSerializer < ActiveModel::Serializer
  attributes :id, :customer_id, :balance, :date
end
