我正在尝试设置我的网站，以便我的工作详细信息的 url 将使用 slug 字段而不是 pk。它告诉我它无法使用给定的 slug （这是一个 int，147）找到我的工作。

Update:

查看 DetailView 描述后https://ccbv.co.uk/projects/Django/1.11/django.views.generic.detail/Det​​ailView/ https://ccbv.co.uk/projects/Django/1.11/django.views.generic.detail/DetailView/我意识到有一个slug_field属性为DetailView。我的新视图如下所示：

class JobDetailView(CacheMixin, DetailView):
    model = Job
    slug_field = 'slug'

问题：

urls:

urlpatterns = [
    url(r'^careers$', views.job_list, name='job-list'),
    url(r'^careers/(?P<slug>[0-9]+)/$', views.JobDetailView.as_view(), name='job-detail'),
]

view:

class JobDetailView(CacheMixin, DetailView):
    model = Job
    pk_url_kwarg = 'slug'
    def get_object(self, *args, **kwargs):
        # Call the superclass
        object = super(JobDetailView, self).get_object()
        # Return the object
        return object

    def get(self, request, *args, **kwargs):
        object = super(JobDetailView, self).get(request, *args, **kwargs)
        return object

model:

class Job(UpdateAble, PublishAble, models.Model):
    slug = models.CharField(unique=True, max_length=25)
    facility = models.ForeignKey('Facility')
    recruiter = models.ForeignKey('Recruiter')
    title = models.TextField()
    practice_description = models.TextField(blank=True, default="")
    public_description = models.TextField(blank=True, default="")

    objects = JobManager()

    def get_next(self, **kwargs):
        jobs = Job.objects.published()
        next = next_in_order(self, qs=jobs)
        if not next:
            next = jobs[0]
        return next

    def get_prev(self, **kwargs):
        jobs = Job.objects.published()
        prev = prev_in_order(self, qs=jobs)
        if not prev:
            prev = jobs[len(jobs)-1]
        return prev

    def __str__(self):
        return f'{self.facility}; {self.title}'

manager:

class JobManager(models.Manager):

    def published(self):
        return super(JobManager, self).get_queryset().filter(is_published=True).order_by('facility__name', 'title')

你实际上不需要定义pk_url_kwarg根本没有，事实上，这样做会让事情变得混乱，导致找不到对象。

正如你可以看到的默认实现get_object http://ccbv.co.uk/projects/Django/1.11/django.views.generic.detail/SingleObjectMixin/#get_object，视图通常寻找pk or slugURL 中的 kwarg；无论找到什么，都将用于查找。但通过设置pk_url_kwarg to slug，您告诉视图获取名为“slug”的 URL kwarg，但是用它来查找PK场，这显然行不通。

只需完全删除该属性，Django 将检测您的 slug kwarg 并使用它来正确查找 slug 字段。
