正在将Json对象数组上载到Firestore

Question

我有一个有序但很大的Json对象数组，它遵循以下结构：

{
"object1":[
{
"data1":19.77,
"data2":-0.953125,
"data3":-0.265625,
"id":17231,
"date":"2021-05-14/08:38:47.471"
},
{
"data1":19.77,
"data2":-0.953125,
"data3":-0.265625,
"id":17231,
"date":"2021-05-14/08:38:47.596"
},
{
"data1":19.77,
"data2":-0.9609375,
"data3":-0.2734375,
"id":17231,
"date":"2021-05-14/08:38:47.721"
}
],
"object2":[
{
"data1":19.91,
"data2":-0.9765625,
"data3":-0.109375,
"id":18996,
"date":"2021-05-14/08:38:47.681"
},
{
"data1":19.91,
"data2":-0.9765625,
"data3":-0.109375,
"id":18996,
"date":"2021-05-14/08:38:47.806"
},
{
"data1":19.91,
"data2":-1,
"data3":-0.1171875,
"id":18996,
"date":"2021-05-14/08:38:47.931"
},
{
"data1":19.91,
"data2":-0.96875,
"data3":-0.1015625,
"id":18997,
"date":"2021-05-14/08:38:48.051"
},
{
"data1":19.91,
"data2":-0.96875,
"data3":-0.1015625,
"id":18997,
"date":"2021-05-14/08:38:48.059"
},
{
"data1":19.91,
"data2":-0.9765625,
"data3":-0.109375,
"id":18997,
"date":"2021-05-14/08:38:48.176"
}
]
}

我一直试图将它上传到firebase，但没有成功，我试图在Firestore:中遵循这个模式

Objects
├───Object1
│   ├───[Upload Timestamp]
│   │   └───Data Array 1
│   ├───[Upload Timestamp]
│   │   └───Data Array 2
│   └───[Upload Timestamp]
│       └───Data Array 3
└───Object2
├───[Upload Timestamp]
│   └───Data Array 1
├───[Upload Timestamp]
│   └───Data Array 2
├───[Upload Timestamp]
│   └───Data Array 3
├───[Upload Timestamp]
│   └───Data Array 4
├───[Upload Timestamp]
│   └───Data Array 5
└───[Upload Timestamp]
└───Data Array 6

我试着用嵌套的For Loops、Dictionaries之类的东西来做这件事，但没有成功。到目前为止，我只能将每个对象的最后一个数据数组上传到Firestore。

有没有一种方法可以把它正确地上传到Firestore？

编辑：添加有关我的代码的更多信息

我有什么：

import firebase_admin
from firebase_admin import credentials
from firebase_admin import firestore
import json
from itertools import groupby
import datetime
from datetime import date
today = date.today()
d1 = today.strftime("%d.%m.%Y")
json_file_path = "./myfile.json" 
with open(json_file_path, 'r') as j:
contents = json.loads(j.read())
data = {}
#Sorting my json file
for key, items in groupby(sorted(contents, key = lambda x: (x['id'], x['date'])), key=lambda x: x['id']):  
data[key] = list(items)
cred = credentials.Certificate("myAppCreds.json")
firebase_admin.initialize_app(cred, {
'projectId': "MyProjectID",
})
db = firestore.client()
for keys in data:
doc_ref = db.collection('Objects').document(keys).collection(d1).document(str(datetime.datetime.now()))
for info in data[keys]:
doc_ref.set(keys)

发生了什么：

以下条目在Firestore中创建：

Objects/object1/19.05.2021/2021-05-19 13:26:03.933868

在文件"；2021-05-19 13:26:03.933868"；使用新值不断更新，而不是为每个新值创建一个新值。object2也是如此

这是一份工作草案，其中有一些注释：

import firebase_admin
from firebase_admin import credentials
from firebase_admin import firestore
import json
from datetime import date
today = date.today()
d1 = today.strftime("%d.%m.%Y")
json_file_path = "./myfile.json" 
with open(json_file_path, 'r') as j:
contents = json.loads(j.read())
# 1. This will be the criteria to sort each inner list
# first by ID, then by date, ascending
def _sort(item):
return (item['id'], item['date'])
# 2. Sorting my json file lists, in place
for lista in contents.values():
lista.sort(key=_sort)
cred = credentials.Certificate("myAppCreds.json")
firebase_admin.initialize_app(cred, {
'projectId': "MyProjectID",
})    
db = firestore.client()
# Inside the collection Objects, I create a document for each object key,
# Then set the inner list as an inner document, with value equals to the list.
for key, lista in contents.items():
doc_ref = db.document('Objects/' + key).set({'lista': lista})

这不会完全按照id/日期进行排序，因为对象是单独排序的。您可能需要对此进行调整。

在firebase中，我已经成功地创建了运行此代码的文档。
