【问题描述】：

我有这样的模型：

class Region(models.Model):
    region_parent = models.ForeignKey(
        "self", blank=True, null=True, on_delete=models.CASCADE)
    name = models.CharField(max_length=255)
    title = models.CharField(max_length=255)
    description = RichTextField()
    description_on_list = RichTextField(blank=True)
    thumbnail = models.ImageField(
        upload_to="thumbnail-region", blank=True, max_length=255)
    sidebar = RichTextField(blank=True)
    ad_manager = models.TextField(blank=True)
    meta_keywords = models.TextField(blank=True)
    logo_on_navbar = models.ImageField(
        upload_to="logo-on-navbar/", blank=True, max_length=255)
    display_on_navbar = models.BooleanField(default=True)
    slug = models.SlugField(unique=True)

def get_absolute_url(self):
    if self.region_parent is not None:
        return reverse('vineyards:region', kwargs={'parent': self.region_parent.slug, 'region': self.slug})
    else:
        return reverse('vineyards:region-without-parent', kwargs={'region': self.slug})


class Vineyard(models.Model):
    name = models.CharField(max_length=255)
    text = RichTextField()
    rating = models.FloatField()
    custom_overlay = models.ImageField(
        upload_to="custom-rating/", blank=True, max_length=255)
    google_map = models.TextField()
    wine_rg_url = models.URLField(blank=True)
    wine_rg = models.CharField(max_length=255)
    wines_url = models.URLField(blank=True)
    wines = models.CharField(max_length=255)
    size = models.CharField(max_length=255)
    grapes = models.CharField(max_length=255)
    owner_url = models.URLField(blank=True)
    owner = models.CharField(max_length=255)
    visits = models.CharField(max_length=255)
    region = models.ForeignKey(Region, on_delete=models.CASCADE)
    regions = models.ManyToManyField(
        Region, blank=True, related_name="regions")
    cover = models.ImageField(upload_to="vineyard/", max_length=255)
    sidebar = RichTextField(blank=True)
    ad_manager = models.TextField(blank=True)
    meta_keywords = models.TextField(blank=True)
    top_slider = models.BooleanField(default=False)
    cover_slider = models.BooleanField(default=False)
    hide_rating = models.BooleanField(default=False)
    slug = models.SlugField(unique=True)

def get_absolute_url(self):
    if self.region.region_parent is not None:
        return reverse('vineyards:detail', kwargs={'parent': self.region.region_parent.slug, 'region': self.region.slug, 'slug': self.slug})
    else:
        return reverse('vineyards:detail-without-parent', kwargs={'region': self.region.slug, 'slug': self.slug})

这是我的 urls.py：

app_name = 'vineyards'
urlpatterns = [
    path('<str:parent>/<str:region>/<slug:slug>/form/',
         rr_form, name="detail-form"),
    path('<str:region>/<slug:slug>/form/',
         rr_form, name="detail-without-parent-form"),
    path('<str:parent>/<str:region>/', vineyard_region, name="region"),
    path('<str:region>/', vineyard_region, name="region-without-parent"),
    path('<str:parent>/<str:region>/<slug:slug>/',
         vineyard_detail, name="detail"),
    path('<str:region>/<slug:slug>/',
         vineyard_detail, name="detail-without-parent"),
]

问题是，我无法访问最后 2 条路径（葡萄园：detail，葡萄园：detail-without-parent）。我认为问题出在网址的顺序上。我尝试了不同的顺序，但结果总是只有一个或一些 url 有效，而不是全部。

是否可以有一个具有相同路径的 url，如下所示：slug/slug/？或者我应该将 url 分成两个不同的文件？有什么建议吗？

谢谢。

【解决方案1】：

您的网址路径必须是唯一的。否则 Django 应该如何知道请求使用哪个路径？

如果多个路径匹配 url 模式，Django 将使用第一个匹配的路径。

在您的路径中使用独特的网址格式。例如，

#this is just an example, adjust as it makes sense by your app logic

    path('parent/<str:parent>/<str:region>/<slug:slug>/',
         vineyard_detail, name="detail"),
    path('detail/<str:region>/<slug:slug>/',
         vineyard_detail, name="detail-without-parent"),
