Question

我正在我的应用程序上实现某种搜索机制，试图从输入中获取查询，在数据库（sqlite）中查找并将其呈现为模板。问题是我遇到了错误：

.views没有返回HttpResponse对象。它返回None。

逻辑就像：
1）制作将检查给定查询的功能

def search_query(request,search,query):

    checking = check_in(query) #check if query is in DB

    if checking == False: #if not, get data from search api and save it
        search_querys = requests.get(search)
        json_search = search_querys.json()   
        for each in json_search['data']:    
            user_id = each['id']
            name = each['name']
            picture = each['picture']['data']['url']
            Profiles.objects.create(user_id=user_id, name=name, picture=picture)

        return render(request, 'FB_search/home.html') 

    else:   # <--assuming that here's the problem. For testing purpose, I'm writing query for which I know that they are in DB and I'd like to return in tamplet
        context = {
            'profiles': Profiles.objects.filter(Q(user_id__startswith=query) | Q(name__startswith=query))
        }       

        return render(request, 'FB_search/home.html', context)

2）在我的端点中调用上面的函数，例如：

def api_search(request):
    if request.method == "GET":
       query = request.GET.get('q')
       search = 'some API with {query} inside it' 
       search_query(request,search,query)

当我尝试调用“搜索查询”功能时，出现提示错误。有什么建议吗？

谢谢。

您没有返回search_query的返回值，应该返回它：

def api_search(request):
    if request.method == "GET":
       query = request.GET.get('q')
       search = 'some API with {query} inside it' 
       return search_query(request,search,query)

视图没有返回HttpResponse对象。它返回None
