如何在 Django 2.1 中将多个 slugs 添加到一个 url 路径中？

我想要一个像这样的 URL 路径： www.example.com/bachelor/frankfurt-university/corporate-finance

如您所见，本示例中的 URL 路径包含 3 个 slugs。

对于这些类别，我有 3 个不同的类别。 slug 分别包含在它们各自的内部。我需要做什么才能实现这种类型的 URL 路径？我可以使用单个 slug 来创建 URL 路径，但不能使用多个 slug 来创建 URL 路径。

每一个帮助或想法都受到高度赞赏。我找不到任何来源。

URLS.py

app_name = 'mnsdirectory'
urlpatterns = [
    path('', views.IndexView.as_view(), name='index'), #views.index
    path('study/<slug:studylevelslug>/<slug:subjectslug>/', views.SubjectDetailView.as_view(), name='subject-detail'),
    path('study-abroad/<slug:studylevelslug>/', views.StudylevelDetailView.as_view(), name='studylevel-list'),
    ]

VIEWS.py

class IndexView(generic.ListView):
    model = Programmesearch
    template_name = 'mnsdirectory/index.html'
    context_object_name = 'universities'
    queryset = Programmesearch.objects.all()[:6]
    def get_context_data(self, **kwargs):
        context = super(IndexView, self).get_context_data(**kwargs)
        context['studylevels'] = StudyLevel.objects.all()[:10]
        return context

class SubjectDetailView(generic.DetailView):
    model = Programmesearch
    template_name = 'mnsdirectory/subject_detail.html'
    slug_field = 'subjectslug'
    slug_url_kwarg = 'subjectslug'

class StudylevelDetailView(generic.DetailView):
    model = StudyLevel
    template_name = 'mnsdirectory/study_level.html'
    slug_field = 'studylevelslug'
    slug_url_kwarg = 'studylevelslug'

模型.py

class Programmesearch(models.Model):
    study_country = models.CharField(max_length=100, 
        choices=COUNTRY_CHOICE)
    full_subject_name = models.CharField(max_length=100, blank=True, 
        null=True)

    def get_unique_slug(self):
        subjectslug = slugify(self)
        unique_slug = subjectslug
        counter = 1
        while mnsdirectory.objects.filter(subjectslug = unique_slug).exists():
            unique_slug = '{}-{}'.format(subjectslug, counter)
            counter += 1
        return unique_slug

    subjectslug = models.SlugField(unique=True)

    def __str__(self):
        return self.subjectslug

    def get_absolute_url(self):
        return reverse('SubjectDetailView', args=[str(self.id)])

def pre_save_programmesearch_receiver(sender, instance, *args, **kwargs):
    subjectslug = slugify(instance.full_subject_name)
    exists = Programmesearch.objects.filter(subjectslug=subjectslug).exists()
    if exists:
        subjectslug = "%s-%s" %(subjectslug, instance.id)
    instance.subjectslug = subjectslug

pre_save.connect(pre_save_programmesearch_receiver, sender=Programmesearch)

class StudyLevel(models.Model):
    title = models.CharField(max_length=100, blank=True, null=False)
    studylevelslug = models.SlugField(unique=True, editable=False, max_length=100)

    def __str__(self):
        return self.studylevelslug

    def get_absolute_url(self):
        return reverse('StudylevelDetailView', args=[str(self.id)])

    def get_unique_slug(self):
        studylevelslug = slugify(self.study_level)
        unique_slug = studylevelslug
        counter = 1
        while StudyLevel.objects.filter(studylevelslug = unique_slug).exists():
            unique_slug = '{}-{}'.format(studylevelslug, counter)
            counter += 1
        return unique_slug

def pre_save_studylevel_receiver(sender, instance, *args, **kwargs):
    studylevelslug = slugify(instance.study_level)
    exists = StudyLevel.objects.filter(studylevelslug=studylevelslug).exists()
    if exists:
        studylevelslug = "%s-%s" %(studylevelslug, instance.id)
    instance.studylevelslug = studylevelslug

pre_save.connect(pre_save_studylevel_receiver, sender=StudyLevel)

我遇到了同样的问题，你可以存储并传递你的第一个slugslug:studylevelslug（使用会话或将其保存为模型中的字段）然后将 multi slug 传递到您的 url 路径，就像您在代码中所做的那样：path('study/<slug:studylevelslug>/<slug:subjectslug>/', views.SubjectDetailView.as_view(), name='subject-detail'),当你打电话时在你的模板中{% url %}像这样传递你的蛞蝓：

{% url 'subject-detail' studylevelslug=YOURFIRSTSLUG subjectslug=YOURSECONDSLUG  %}

我在我的项目中使用了它并且它工作得很好。 有关如何在会话中存储 slug 的更多详细信息，请使用此链接：Django中如何使用session https://www.tutorialspoint.com/django/django_sessions.htm
