I'm developing a simple blog to learn Django. I would like to have a path for each posts like this:

• /category-1/title-post


• /category-2/title-post


• etc..

Below urls.py

from django.urls import include, path

from .views import CategoryList, PostList, SingleCategory, SinglePost, SingleTag, TagList



urlpatterns = [

        path("", PostList.as_view(), name="list_post"),

        path("<slug:slug>", SinglePost.as_view(), name="single_post"),

        path("tags/", TagList.as_view(), name="list_tag"),

        path("tags/<slug:slug>", SingleTag.as_view(), name="single_tag"),

        path("categories/", CategoryList.as_view(), name="list_category"),

        path("categories/<slug:slug>", SingleCategory.as_view(), name="single_category"),

]

And views.py

from django.shortcuts import render

from django.views.generic.list import ListView

from django.views.generic.detail import DetailView



from .models import Category, Post, Tag

# Create your views here.



class CategoryList(ListView):

    model = Category

    context_object_name = 'category_list'

    template_name = "list_category.html"





class SingleCategory(DetailView):

    model = Category

    template_name = "single_category.html"





class PostList(ListView):

    model = Post

    queryset = Post.objects.order_by('-id')

    context_object_name = 'post_list'

    template_name = "list_post.html"

    paginate_by = 4





class SinglePost(DetailView):

    model = Post

    template_name = "single_post.html"





class TagList(ListView):

    model = Tag

    context_object_name = 'tag_list'

    template_name = "list_tag.html"





class SingleTag(DetailView):

    model = Tag

    template_name = "single_tag.html"

Here models.py

class Category(models.Model):

    category_name = models.CharField(

                max_length=50,

                )

    slug = models.SlugField(

                unique=True,

                )



    def __str__(self):

        return self.category_name



    def get_absolute_url(self):

        return reverse("single_category", kwargs={"slug": self.slug})





class Post(models.Model):

    title = models.CharField(

                max_length=50,

                )

    slug = models.SlugField(

                unique=True,

                )

    content = models.TextField()

    tag = models.ManyToManyField(

                Tag,

                related_name="tag_set",

                )

    category = models.ForeignKey(

                    Category,

                    on_delete=models.CASCADE,

                    related_name="category_set",

                    )

    highlighted = models.BooleanField(

                    default=False,

                    )



    def __str__(self):

        return self.title



    def get_absolute_url(self):

        return reverse("single_post", kwargs={"slug": self.slug})



    class Meta:

        ordering = ['-id']

I don't understand how I can change the path "categories/" in "category-slug/". I would like to do a same thing for categories / , that must change in category-slug/post-slug.

How I can do this using the Class Based View?

You can define as many parameters in your URL as you like. Then you'll need to override get_object to get the relevant post by slug and category.

path('<slug:category_slug>/<slug:post_slug>', SinglePostByCategory.as_view(), 'single_post_by_category')

...

class SinglePostByCategory(DetailView):

    def get_queryset(self):

        return get_object_or_404(Post,

            category__slug=self.kwargs['category_slug'],

            slug=self.kwargs['post_slug']

        )
