Django表示反向为''与参数'（7，）'和关键字参数'{}'未找到 [英] Django forms Reverse for '' with arguments '(7,)' and keyword arguments '{}' not found

问题描述

我过去一天遇到这个错误，似乎无法解决。

I have been running into this error for the past day and can't seem to solve it.

Reverse for '' with arguments '(7,)' and keyword arguments '{}' not found.

我的目标是让用户从我的drui_index页面选择一种疾病。然后将用户带到drui页面添加或编辑指标。在我的模型中，每个疾病都有多个指标。当我到达drui页面，我得到上面的错误，我不知道为什么。错误中的7是疾病表中的PK。

My goal is to have a user select a disease from my drui_index page. Then the user is taken to the drui page to add or edit the indicators. In my models, there are multiple indicators for each disease. When I get to the drui page, I get the error above and am not sure why. The '7' in the error is the PK from the disease table.

Views.py

def drui_index(request):
   disease_list = Disease.objects.all()
   context = {'disease_list':disease_list}
   return render(request, 'drui_index.html', context)


def drui(request, disease_id):
   disease = get_object_or_404(Disease, pk=disease_id)  

   if request.method == "POST":

      diseaseForm = DiseaseForm(request.POST, instance=disease)
      indicatorInlineFormSet = IndicatorFormSet(request.POST, request.FILES, instance=disease)

      if diseaseForm.is_valid():
         new_disease = diseaseForm.save(commit=False)
         indicatorInlineFormSet.save()
         return HttpResponseRedirect(reverse('drui', kwargs={'disease_id':disease_id}))

   else:
      diseaseForm = DiseaseForm(instance=disease)
      indicatorInlineFormSet = IndicatorFormSet(instance=disease)

   return render(request, 'drui.html', {'disease':disease, 'diseaseForm':diseaseForm, 'indicatorInlineFormSet': indicatorInlineFormSet}) 

HTML drui.html

 <form class="disease_form" action="{% url drui disease.id %}" method="post">{% csrf_token %}
  {{ disease }}
  {{ diseaseForm.as_table }}
  {{ indicatorInlineFormSet.as_table }}

urls.py

url(r'^drui_index/$', 'Physician_UI.views.drui_index', name='drui_index'),
url(r'^drui_index/(?P<disease_id>\d+)/$', 'Physician_UI.views.drui', name='drui'),

forms.py

class DiseaseForm(forms.ModelForm):
    disease = forms.ModelChoiceField(queryset=Disease.objects.all())

    class Meta:
       model = Disease

IndicatorFormSet = inlineformset_factory(Disease, 
    Indicator,
    can_delete=False,
    extra=MAX_INDICATORS)

在我的views.py中，我不认为我需要调用diseaseForm，因为我已经在drui_index中选择了一种疾病。但是，我不认为这是导致这个问题。

In my views.py, I don't think I need to call the diseaseForm because I have already chosen a disease in drui_index. However, I don't think that's causing the problem.

推荐答案

我觉得你在url名字中缺少引号：

I think you are missing quotes around url name:

{% url drui disease.id %}

应该是（如果你使用django> = 1.5）或者使用 {％从未来％}加载url 在模板中：

Should be (if you are using django >= 1.5) or using {% load url from future %} in template:

{% url "drui" disease.id %}
