python - Django - /uploaddd 上的 TypeError 不可散列类型：'dict'

Question

当我点击函数上传时，我试图将文档对象作为 json 返回。我收到以下错误

/uploaddd 上的 TypeError 不可散列类型：'dict'

这是功能

def uploaddd(request):
    documents = {
        {
            "@search.action": "upload",
            "HotelId": "1",
            "HotelName": "Secret Point Motel 2020",
            "Description": "The hotel is ideally located on the main commercial artery of the city in the heart of New York. A few minutes away is Time's Square and the historic centre of the city, as well as other places of interest that make New York one of America's most attractive and cosmopolitan cities.",
            "Description_fr": "L'hôtel est idéalement situé sur la principale artère commerciale de la ville en plein cœur de New York. A quelques minutes se trouve la place du temps et le centre historique de la ville, ainsi que d'autres lieux d'intérêt qui font de New York l'une des villes les plus attractives et cosmopolites de l'Amérique.",
            "Category": "Boutique",
            "Tags": [ "pool", "air conditioning", "concierge" ],
            "ParkingIncluded": "false",
            "LastRenovationDate": "1970-01-18T00:00:00Z",
            "Rating": 3.60,
            "Address": {
                "StreetAddress": "677 5th Ave",
                "City": "New York",
                "StateProvince": "NY",
                "PostalCode": "10022",
                "Country": "USA"
            }
        },
    
    }    
    return JsonResponse({'doc': documents })

问题是对象“国家”的最新条目：“美国”

有任何想法吗？

编辑 - 这显示了包含在对象中的多个文档。
