Django url 路径匹配未按预期工作

Question

我对 Django 模型 get_absolute_url 反向方法有疑问。我有一个完美运行的 url 模式，但问题是

当我访问 example.com/blog/python/first-post 时，路径完美运行，但是当我尝试像 example.com/blog/python-randomr9353/first-post 这样的随机路径时它仍然可以正常工作，即使它不应该因为 python-randomr9353 不是一个有效的路径，它应该 return a page not found error.

这是我的代码。

class ArticleSeries(models.Model):
    title = models.CharField(max_length=200)
    series_slug = AutoSlugField(populate_from='title')

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('blog:article_list', kwargs={'series_slug': self.series_slug})


class Tag(models.Model):
    title = models.CharField(max_length=50)

    def __str__(self):
        return self.title


class Article(models.Model):
    title = models.CharField(max_length=200)
    article_slug = AutoSlugField(populate_from='title')
    tag = models.ManyToManyField(Tag, default=1, verbose_name='Tag')
    series = models.ForeignKey(ArticleSeries, default=1, verbose_name='Series', on_delete=models.SET_DEFAULT)

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('blog:article_detail', args=(self.series.series_slug, self.article_slug))

url 模式

app_name = 'blog'
urlpatterns = [
    path('', views.IndexView.as_view(), name='index_view'),
    path('blog', views.BlogView.as_view(), name='blog_view'),
    path('blog/<slug:series_slug>', views.ArticleListView.as_view(), name='article_list'),
    path('blog/<slug:series_slug>/<slug:article_slug>', views.ArticleDetailView.as_view(), name='article_detail'),
]

尝试在 urls.py 中使用 path('blog/python/<slug:article_slug>', views.ArticleDetailView.as_view(), name='article_detail') 而不是 path('blog/<slug:series_slug>/<slug:article_slug>', views.ArticleDetailView.as_view(), name='article_detail')。

编辑:
在您获得 series_slug 的值时，请自行验证它。

...
validSeries = ['python', 'c', 'cpp', 'js'] # etc
if series_slug not in validSeries:
    # Raise a page not found error
