如何在Django Web应用程序中添加子弹

Question

[这里是问题：我正在尝试“刷新”我的django网络博客，因此，我不想拥有/post/2/，而是拥有了与我的标题完全相同的链接（这样的名称：/post/today-is-friday

这里有一些代码，我已经尝试了几件事，但是没有任何效果：

models.py

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse
from django.template.defaultfilters import slugify

class Post(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    categories = models.ManyToManyField('Category', related_name='posts')
    image = models.ImageField(upload_to='images/', default="images/None/no-img.jpg")
    slug= models.SlugField(max_length=500, unique=True, null=True, blank=True)

    def save(self, *args, **kwargs):
        self.url= slugify(self.title)
        super(Post, self).save(*args, **kwargs)

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('post-detail', kwargs={'pk': self.pk})


class Category(models.Model):
    name = models.CharField(max_length=20)

    def __str__(self):
        return self.name

urls.py

from django.urls import path
from django.conf.urls import include, url
from . import views
from .views import PostListView, PostDetailView, PostCreateView, PostUpdateView, PostDeleteView, UserPostListView

urlpatterns = [
    #Blog section
    path("", PostListView.as_view(), name='blog-home'),
    path("user/<str:username>", UserPostListView.as_view(), name='user-posts'),
    path("post/<int:pk>/", PostDetailView.as_view(), name='post-detail'),
    path("post/new/", PostCreateView.as_view(), name='post-create'),
    path("post/<int:pk>/update/", PostUpdateView.as_view(), name='post-update'),
    path("post/<int:pk>/delete/", PostDeleteView.as_view(), name='post-delete'),
    path("about/", views.about, name="blog-about"),
    path("<category>/", views.blog_category, name="blog_category"),
]

您应该在视图中使用lookup_field='slug'

class YourView(generics.GenericAPIView):
    lookup_field = 'slug'

并在urls.py中进行更改

path("post/<str:slug>/" ...)
