错误告诉你到底发生了什么：你的“jobpost_detail” URL 捕获了一个slug 参数并将其传递给视图，但该视图不需要一个 slug，只有请求和一个模板。此外，在这种情况下，您并没有做任何事情来获得由 slug 识别的实际帖子：您总是得到第一个发布的帖子。

我怀疑您想要执行以下操作：

def jobpost_detail(request, slug, template="careers/jobpost_detail.html"):
    jobposts = JobPost.objects.published()
    jobpost = get_object_or_404(jobposts, slug=slug)
