如何将数组响应包装到rails中的对象

Question

所以我有一个名为history的模型，然后我想渲染它。

我当前的代码是：

class Address < ActiveModel::Serializer
attributes :guid, :name, :address, :latitude, :longitude, :place_id, :notes, :last_used_on
def latitude
object.latitude.to_s
end
def longitude
object.longitude.to_s
end
end

并且响应是

[
{
"guid"=>"Address-35-91526dee",
"name"=>"Lake Johana",
"address"=>"Apt. 951 774 Bruen Mountains, Schneiderchester, OK 90705-0506",
"latitude"=>"67.24423261517666",
"longitude"=>"96.37355099166064",
"place_id"=>"ltpzw5n87w",
"notes"=>"c2rxzesry7",
"last_used_on"=>"2018-11-05 09:56:23 +0700"
},
{
"guid"=>"Address-34-23f95e54",
"name"=>"North Gregoryshire",
"address"=>"64213 Vandervort Trail, North Marinville, CA 70667",
"latitude"=>"-45.928682957769965",
"longitude"=>"124.27899877429144",
"place_id"=>"hwki1m0xwg",
"notes"=>"k34un21zjh",
"last_used_on"=>"2018-11-05 09:56:23 +0700"
}
]

我想要的是将响应封装在addresses中，这样它看起来就像

{
"addresses": [
{
"guid": "AddressHistory-16-58abd401",
"name": "Port Charla",
"address": "5016 Kerstin Brook, West Tanja, MO 02060",
"latitude": "-68.07486131158515",
"longitude": "-8.531218394535387",
"place_id": "9guhaf7o1e",
"notes": "rl5qq7r7cv",
"last_used_on": "2018-11-05 09:42:51 +0700",
},
{
"guid": "AddressHistory-15-86bea685",
"name": "South Vernon",
"address": "1185 Tania Road, South Joeyborough, OK 97125",
"latitude": "84.52009358082654",
"longitude": "87.74343692672034",
"place_id": "hiw08eeh0l",
"notes": "8nn5aiwe9m",
"last_used_on": "2018-11-05 09:42:51 +0700",
}
]
}

a=Hash.new
a['addresses']=response
