def delete(request): form = searchform(request.post)

searched_data = information.objects.filter(name="full_name").count()  d_data = none  if form.is_valid():     if (searched_data == 1):         d_data = information.objects.filter(name= form.cleaned_data.get('full_name')).delete()     else:         d_data = information.objects.filter(name=form.cleaned_data.get('full_name'))   context = {     'form': form,     'd_data': d_data,  }  return render(request, 'delete.html', context) 

i not unless form valid:

if form.is_valid():     d_data = information.objects.filter(name=form.cleaned_data.get('full_name'))      if len(d_data) == 1:         d_data.delete()         d_data = none else:     d_data = none  context = {     'form': form,     'd_data': d_data, }  return render(request, 'delete.html', context) 

note: set d_data none after it's been deleted.
