在Django 2.1中,如何在一个url路径中添加多个slug?

python-3.x django

Ulvi · 技术社区 · 6 年前

我想有一个这样的URL路径: www.example.com/学士/frankfurt-university/corporate-finance

如您所见,在本例中,URL路径包括3个slug。

我有三个不同的班级。弹头分别包含在每个弹头内。我需要做什么才能实现这种类型的URL路径?我可以用一个slug创建URL路径,但不能用多个slug。

每一个帮助或想法都是高度赞赏的。我找不到任何来源。

网址.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'),
    ]

视图.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)

我也有同样的问题,你可以储存并传递你的第一个子弹 slug:studylevelslug (使用会话或将其另存为模型中的字段)然后将multi-slug传递到url路径,与在代码中所做的相同: path('study/<slug:studylevelslug>/<slug:subjectslug>/', views.SubjectDetailView.as_view(), name='subject-detail'), 在你的模板中 {% url %} 像这样把你的鼻涕虫传过去:

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

我在我的项目中用过这个,效果很好。有关如何在会话中存储slug的详细信息,请使用以下链接: How use session in Django

如果你需要任何进一步的帮助,请和将乐意帮助。

一个 DetailView 是为了一个人 object 所以你不能用两个型号。

试试这样的:

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

    def get_study_level(self, *args, **kwargs):
        return StudyLevel.objects.get(slug=subjectslug)

    def get_context_data(self, *args, **kwargs):
        ctx = super().get_context_data(*args, **kwargs)
        ctx['study_level'] = self.get_study_level()
        return ctx

你现在可以访问 对象 和 study_level 在你的模板中。 对象 会抓住你的 Programmsearch 数据和 学习水平 你的 StudyLevel 数据
