我正在尝试运行一个应用模拟器，该模拟器碰到以下API端点：
import json
import logging
from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt
from django.views.decorators.http import require_POST, require_GET
from django.core import exceptions
from django.contrib.auth.password_validation import validate_password
from lucy_web.models import Family, User
logger = logging.getLogger(__name__)
@require_POST
def update_user_via_activation_code(request, version):
username = json.loads(request.body).get('username')
email = json.loads(request.body).get('email')
activation_code = json.loads(request.body).get('activation_code')
password = json.loads(request.body).get('password')
if username is None:
username = email
if len(Family.objects.filter(activation_code=activation_code, employee_user__email__iexact=username)) > 0:
user = Family.objects.get(activation_code=activation_code, employee_user__email__iexact=username).employee_user
elif len(Family.objects.filter(activation_code=activation_code, partner_user__email__iexact=username)) > 0:
user = Family.objects.get(activation_code=activation_code, partner_user__email__iexact=username).partner_user
else:
return JsonResponse({'success': False, 'errors': {'password': 'Activation code and email do not match'}})
try:
validate_password(password, user)
except exceptions.ValidationError as error:
return JsonResponse({'success': False, 'errors': {'password': error.messages[0]}})
user.username = email
user.email = email
user.set_password(password)
user.save()
user.profile.using_app = True
user.profile.save()
if not user.family.status or user.family.status == Family.ENROLLED:
user.family.status = Family.NEW
user.family.save()
return JsonResponse({'success': True})
但是，我遇到了错误

据http://django-auditlog.readthedocs.io/en/latest/usage.html所了解，Django-Auditlog跟踪对象的更改。我认为，我曾经经历过此端点处理的激活流程，这就是为什么我要实施的“更改”之前已经完成并且实际上是幂等的。但是在这种情况下，是否不应该通过时间戳将其与之前的“更改”区分开，而不是因为违反唯一约束而引发错误？我该如何解决这个错误？
