Question

request.GET ['q']， request.GET中（ 'q'），和request.GET中（ 'q'）。謝謝

def search(request): 
    if 'q' in request.GET and request.GET['q']: 
     q=request.GET['q'] 
     books=Book.objects.filter(title__icontains=q) 
     return render(request,'search_results.html',{'book':books,'query':q}) 
    else: 
     return HttpResponse('please submit a search term')
