如何使用 JSON 回應發送每個物件的主鍵？我正在發送 json 回應以根據用戶狀態修改表。一切正常，除了無法獲得與每個用戶關聯的 PK。
目前它發送除 PK 之外的所有值。
class UserByState(View):
page_limit = 100
def get_paginated_context(self, queryset, page, limit):
if not page: page = 1
if limit:
self.page_limit = limit
paginator = Paginator(queryset, self.page_limit)
page_obj = paginator.get_page(page)
serialized_page = serialize("json", page_obj.object_list)
serialized_page = [obj["fields"] for obj in json.loads(serialized_page)]
return {
"data": serialized_page,
"pagination": {
"page": page,
"limit": limit,
"has_next": page_obj.has_next(),
"has_prev": page_obj.has_previous(),
"total": queryset.count()
}
}
def get(self, request, *args, **kwargs):
user = self.request.user
page = request.GET.get('page')
limit = request.GET.get('limit')
state = request.GET.get('state')
queryset = User.objects.all()
if state and state != "all":
queryset = queryset.filter(state=state)
to_return = self.get_paginated_context(queryset, page, limit)
return JsonResponse(to_return, status = 200)
uj5u.com熱心網友回復：
我認為這種理解可能會失去一些價值。
serialized_page = serialize("json", page_obj.object_list)
當你['fields']在這里打電話時：
serialized_page = [obj["fields"] for obj in json.loads(serialized_page)]
您只獲得關鍵“欄位”的值。這就像標準字典。
fields = {"first_name": "Dan", "last_name": "ram", "address": "6090 DRAGON WAY", "city": "CREST", "state": "CA", "zipcode": 91912}
試試看：
serialized_page = serialize("json", page_obj.object_list)
serialized_page = [{**obj["fields"], **{"pk": obj["pk"]}} for obj in json.loads(serialized_page)]
