我正在尝试一个简单的事情用户点击显示的问题。点击时的链接将接收问题ID并将其作为参数传递以显示相关的选择。用户被要求选择一个选择,然后下一页将显示有多少人投票选择了该选项(包括用户当前的决定)。 我得到的错误是当我使用127.0.0.1:8000/polls/启动应用程序时,它显示了问题。然后,当我点击这个问题的网址变成127.0.0.1:8000/polls/3/这是正确的,因为3是问题ID。因此预计会显示问题ID的选项。但它没有显示。 错误是:如何将Django模板中的多个参数传递给通过URL查看?
NoReverseMatch at /polls/3/
Reverse for 'results' with arguments '()' and keyword arguments '{'q_id': 3, 'c_test': 'May Be'}' not found. 1 pattern(s) tried: ['polls/(?P<q_id>[0-9]+)/(?P<c_test>\\w+)/results/$']

我的代码是:
views.py
class IndexView(generic.ListView):
template_name = "polls/index.html"
context_object_name = "latest_question_list"
model = Question
def get_queryset(self):
return Question.objects.filter(
pub_date__lte=timezone.now()
).order_by('-pub_date')[:5]
class DetailView(ListView):
model = Choice
context_object_name = "latest_choice_list"
template_name = "polls/detail.html"
def get_queryset(self):
print(self.args[0])
'''Return list of choices'''
return Choice.objects.filter(question_id=self.args[0])
# return Choice.objects.all()
def pollvote(request, q_id, c_test):
if c_test:
p = Choice.objects.filter(question_id=q_id).get(choice_test=c_test)
count = p.votes
count += 1
p.votes = count
p.save()
return HttpResponseRedirect('/polls/%s/%s/results/' % c_test, q_id)
detail.html
{% load staticfiles %}
<link rel="stylesheet" type="text/css" href="{% static 'polls/style.css' %}" />
{% if latest_choice_list %}
<p>Cast your Choice</p>
<ul>
{% for choice in latest_choice_list %}
<li><a href="{% url 'polls:results' q_id=choice.question_id c_test=choice.choice_test%}">{{ choice.choice_test }}</a></li>
{% endfor %}
</ul>
{% else %}
<p>No choice are available.</p>
{% endif %}
结果(误差在href行说的问题) .html:
{% load staticfiles %}
<link rel="stylesheet" type="text/css" href="{% static 'polls/style.css' %}" />
{% if latest_choice_list %}
<p>Choices Made So Far</p>
<ul>
{% for choice in latest_choice_list %}
<li>{{ choice.choice_test }} - {{ choice.votes }} </li>
{% endfor %}
</ul>
{% else %}
<p>No choice are available.</p>
{% endif %}
urls.py
urlpatterns = [
url(r'^$', views.IndexView.as_view(), name='index'),
url(r'^([0-9]+)/$', views.DetailView.as_view(), name='detail'),
url(r'^(?P<q_id>[0-9]+)/(?P<c_test>\w+)/results/$', views.pollvote, name='results'),]
为什么detail.html抛出错误?为什么不把两个名为arguement的关键字传递给结果呢?
也许这是Ctrl + V的问题,但view.py中的缩进显然是不正确的 – svfat
没有在真实代码中是正确的。在发布主题时,这是一个复制粘贴问题。 – debayan89
