I am trying to search an item in a form using POST method and I got the results. But when I use Django pagination, I got the results in the first page. When I click the next or 2 button in Django paginator I got an error like this.
The view profiles.views.individual_home didn't return an HttpResponse object. It returned None instead.
Here search form is in one html page and results shown in another html page.
views.py
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")

CodePudding user response：
The idea is to pass the keyword and the location to the context.
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")
