please answer my question and error's pictures ==> enter image description here 请回答我的问题和错误的图片==> 在此处输入图片描述
Your path expects 4 arguments, including a slug at the end: 您的路径需要4个参数,最后包括一个参数:
re_path(r'^(?P<year>\d{4})-(?P<month>\d{1,2})-(?P<day>\d{1,2})/
(?P<slug>[-\w]+) # slug
$/',views.detail,name='detail'),
But in your template it is only passed year, month, and day, no slug: 但是在您的模板中,仅通过了年,月和日,没有任何问题:
href="{% url 'blog:detail'
year=post.published_at.year
month=post.published_at.month
day=post.published_at.day
# slug missing here!: slug=post.slug
%}"
