在JsonField django中更新數據

Question

我想更新django中jsonfield中的json對象，我在更新數據時遇到問題。

我的模型看起來像這樣https://codeshare.io/Gbeonj

我的json看起來像這樣https://codeshare.io/5obDPX

所以基本上json具有錯誤的數據，而不是“ NATIONAL ID Card”，它具有“ NATIONAL ID”，因此我想更新此json對象以具有正確的數據。 這是在說什么

"info": {
        "mobilePhone": "", 
        "firstName": "david", 
        "tags": [], 
        "middleName": "mirale", 
        "gender": "Male", 
        "documentType": "NATIONAL ID", 
        "beneficiary": false, 
        "dateOfBirth": "1995-03-04T08:01:42.165Z", 
        "documentNumber": "519011016721", 
        "dateOfBirthExact": false, 
        "role": "Child", 
        "lastName": "ABSURG0058", 
        "recipient": "Alternate", 
        "homePhone": ""
      }, 

"documentType": "NATIONAL ID",應為“ NATIONAL ID卡”

我正在使用以下腳本來更新服務器中的json對象。

import django
django.setup()

import sys
reload(sys)    # to re-enable sys.setdefaultencoding()
sys.setdefaultencoding('utf-8')


import json
from django.db import transaction
from maidea.apps.mobile.models import MobileDocument


office = 'sa_de'

#we fetch all the mobile documents from that have failed
uploads = MobileDocument.objects.filter(
    status=MobileDocument.ERROR,
    mobile_upload__office__slug=office
)

print('Number of uploads fetched: %d' %(uploads.count()))

with transaction.atomic():
    for upload in uploads:
        for member in upload.data['members']:
            try:
                doc_type_value = member['info'].get('documentType')
            except:
                doc_type_value = None
            if doc_type_value == 'NATIONAL ID':
          doc_type_value = doc_type_value.replace('NATIONAL ID', 'NATIONAL ID Card')
          assert doc_type_value == 'NATIONAL ID Card'
                  upload.save()

問題是該對象沒有被更新，我在做什么錯？

驗證doc_type_value后，您無需將其重新設置為上upload對象，則需要更新上upload對象：

for upload in uploads:
    data = upload.data
    updated_members = []
    for member in data['members']:
        try:
            doc_type_value = member['info'].get('documentType')
        except KeyError:
            pass
        else:
            if doc_type_value == 'NATIONAL ID':
                doc_type_value = 'NATIONAL ID Card'
                member['info']['documentType'] = doc_type_value
        updated_members.append(member)

    data['members'] = updated_members
    upload.data = data
    upload.save()
