我正在嘗試使用 POST 方法在表單中搜索專案并得到結果。但是當我使用 Django 分頁時，我在第一頁得到了結果。當我在 Django 分頁器中單擊下一個或 2 按鈕時，出現這樣的錯誤。
The view profiles.views.individual_home didn't return an HttpResponse object. It returned None instead.
這里的搜索表單在一個 html 頁面中，結果顯示在另一個 html 頁面中。

def individual_home(request):
if request.method == 'GET':
keyword = request.GET.get('keywords')
print(keyword)
location = request.GET.get('location')
print(location)
ind = IndividualProfile.objects.get(user_id=request.user.id)
details = companyjob.objects.filter(
Q(job_title=keyword) | Q(qualification=keyword) | Q(skills_required=keyword) | Q(job_location=location) & Q(closing_date__gte=datetime.date.today()))
if details:
print(details)
count = details.count()
paginator = Paginator(details, 3)
page_number = request.GET.get('page')
page_obj = paginator.get_page(page_number)
return render(request, "individual_home.html",
{'jobs': page_obj,'count': count, 'ind': ind})
else:
return redirect("individual_homes")

uj5u.com熱心網友回復：
這個想法是將關鍵字和位置傳遞給背景關系。
def individual_home(request):
if request.method == 'GET':
keyword = request.GET.get('keywords')
print(keyword)
location = request.GET.get('location')
print(location)
ind = IndividualProfile.objects.get(user_id=request.user.id)
details = companyjob.objects.filter(
Q(job_title=keyword) | Q(qualification=keyword) | Q(skills_required=keyword) | Q(job_location=location) & Q(closing_date__gte=datetime.date.today()))
if details:
print(details)
count = details.count()
paginator = Paginator(details, 3)
page_number = request.GET.get('page')
page_obj = paginator.get_page(page_number)
return render(request, "individual_home.html",
{'keyword':keyword,'location':location,'jobs': page_obj,'count': count, 'ind': ind})
else:
return redirect("individual_homes")
像這樣改變填充。
