字段 'id' 需要一个数字但得到了 'on'
Field 'id' expected a number but got 'on'
我正在做一个包含在 Django 文档中的项目。
当我输入 URL http://localhost:8000/polls/1/vote/
时,我会在下面一行得到错误:
invalid literal for int() with base 10: 'on'
下面几行是我的视图定义:
def vote(request, question_id):
question = get_object_or_404(Question, pk=question_id)
try:
selected_choice = question.choice_set.get(pk=request.POST['choice'])
except(KeyError, Choice.DoesNotExist):
return render(request, 'polls/detail.html', {
'question': question,
'error_message': "You didn't select a choice",
})
else:
selected_choice.votes += 1
selected_choice.save()
return HttpResponseRedirect(reverse('polls:results', args=(question.id,)))
您已在 post 消息中发送了值 "on"
并带有字段 request.POST["choice"]
,这对于需要数字 [=] 的 selected_choice = question.choice_set.get(pk=request.POST['choice'])
来说不是有效的 pk 13=]
