用在URL中的slug

安装 awesome-slugify

sudo pip install awesome-slugify

models.py 建立数据模型

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

from slugify import slugify

class ArticlePost(models.Model):
    author = models.ForeignKey(User,on_delete=models.CASCADE,related_name='article')
    title = models.CharField(max_length=200)
    slug = models.SlugField(max_length=500)
    created = models.DateTimeField(default=timezone.now)
    updated = models.DateTimeField(auto_now=True)
   
    class Meta:
        ordering = ['-updated']
        index_together = ['id','slug']

    def __str__(self):
        return self.title

    def save(self,*args,**kwargs):        #   ①
        self.slug = slugify(self.title)         #   ②
        super(ArticlePost,self).save(*args,**kwargs)

    def get_absolute_url(self):
        return reverse("article:article_detail",args=[self.id,self.slug])

每个数据模型类都有一个save()方法，语句①对此方法进行重写，其目的就是要实现语句②。

urlconf配置如下

re_path(r'^article-detail/(?P<id>\d+)/(?P<slug>[-\w]+)/$', views.article_detail, name="article_detail"),

注意正则表达式的写法，awesome-slugify生成的slug中间有连接符“-”。
