Question

我目前距离将显示器扔到墙上几分钟，所以如果有人可以帮我解决这个问题那就太棒了:)我已经制作了一个GET表格，一旦用户到达，我就会把你送到另一个页面此页面视图假设从URL中获取GET参数，然后决定要显示的内容。但是我遇到了我认为应该是一个简单的if语句的问题，if语句基本上是假设通过检查所有参数是否等于None来检查它们是否通过GET表单来到页面。但由于某些原因，即使所有参数都是None，它也不会检测到它。有谁能看到这个问题？

def browse(request):

    business_industry = request.GET.get('business_industry', None)
    business_address_region = request.GET.get('business_address_region', None)
    keywords = request.GET.get('keywords', None)
    print(business_industry)
    print(business_address_region)
    print(keywords)

    if business_industry and business_address_region and keywords is not None:
        print("If")
    else:
        print("Else")

    job_listings = JobListing.objects.exclude(active_listing=False)

    context_dict = {
        'joblistings': job_listings
    }

    return render(request, 'browse.html', context_dict)
