将 Json 对象数组上传到 Firestore

问题描述

我有一个遵循以下结构的有序但又大的 Json 对象数组：

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

而且我一直在尝试将其上传到 firebase，但没有成功，尝试在 Firestore 中遵循此架构：

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

我尝试使用嵌套的 For 循环、字典和诸如此类的东西，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。

有什么方法可以将其正确上传到 Firestore 吗？

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：

在 Firestore 中创建了以下条目：

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

文档“2021-05-19 13:26:03.933868”不断更新新值，而不是为每个新值创建一个新值。 object2

也是如此

解决方法

这是一个工作草案，有一些评论：

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})

这不会绝对按 id/date 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，我已成功创建了运行此代码的文档。
