我正在尝试使用两个子段来生成某种类型的帖子的网址。我的网站按类别划分,每个人都有一个或多个帖子。
views.py
def singlePost(request, slug_post):
blogpost = get_object_or_404(BlogPost, slug_post=slug_post)
context = {"blogpost": blogpost}
return render(request, "blog/single_post.html", context)
def singleCategory_postList(request, slug_category):
category = get_object_or_404(Category, slug_category=slug_category)
blogpost = BlogPost.objects.filter(category=category)
context = {
"category": category,
"blogpost": blogpost,
}
return render(request, "blog/single_category.html", context)
我使用的urls.py
path("category/<slug:slug_category>/", views.singleCategory_postList, name="single_category"),
path("<slug:slug_post>/", views.singlePost, name='single_blog_post'),
我要使用的urls.py
path("<slug:slug_category>/", views.singleCategory_postList, name="single_category"),
path("<slug:slug_category>/<slug:slug_post>/", views.singlePost, name='single_blog_post'),
当我使用第二条路径时,显示如下:
/ blog / gis /
中的NoReverseMatch带有关键字参数'{'slug_post'的'single_blog_post'的反向: 找不到'rete-dei-sottoservizi-quadro-normativo'}。 1个图案 尝试过: ['blog \ /(?P [-a-zA-Z0-9 _] +)\ /(?P [-a-zA-Z0-9 _] +)\ / $']
models.py
class Category(models.Model):
category_name = models.CharField(
max_length=50,
verbose_name="Categorie",
help_text="Every category must be not longer then 50 characters",
unique=True,
)
slug_category = models.SlugField(
verbose_name="Slug",
unique=True,
help_text="Slug is a field in autocomplete mode, but if you want you can modify its contents",
)
....
def __str__(self):
return self.category_name
def get_absolute_url(self):
return reverse("single_category", kwargs={"slug_category": self.slug_category})
class BlogPost(ModelPost, TimeManager):
category = models.ForeignKey(
Category,
on_delete=models.CASCADE,
related_name="category_set",
verbose_name="Categorie",
help_text="Select a category for this article.You can select only one category.",
)
keyconcepts = models.ManyToManyField(
KeyConcept,
related_name="keyconcept_blog_set",
help_text="Select a key concept for this article. You can select one or more key concepts.",
verbose_name="Concetti chiave",
)
.....
def get_absolute_url(self):
return reverse("single_blog_post", kwargs={"slug_post": self.slug_post})
在this answer中说明了如何做与我尝试做的事情相同的事情,但是对我而言,它不能很好地工作,我也不明白为什么。
答案 0 :(得分:2)
但是就像您说的那样,URL包含两个子段,因此您需要在反向调用中将它们都传递。并且您需要使用与URL模式本身相同的名称。
$ npm run build
$ sudo vcg

由于丹尼尔·罗斯曼(Daniel Roseman)的指示,我做了一些进一步的更改就解决了我的问题。
这是新的singlePost函数:
def singlePost(request, slug_post, slug_category):
category = get_object_or_404(Category, slug_category=slug_category)
blogpost = get_object_or_404(BlogPost, slug_post=slug_post)
category_blogpost = BlogPost.objects.filter(category=category)
context = {"category": category, "blogpost": blogpost, "category_blogpost": category_blogpost}
return render(request, "blog/single_post.html", context)
下面是Daniel Roseman的代码:
return reverse("single_blog_post", kwargs={"slug_post": self.slug_post, "slug_category": self.category.slug_category})
现在我可以在我的网站中使用两个子弹
