/admin/pages/ 鹡鸰上的 NoReverseMatch

Question

我收到以下错误，无法找出错误所在

NoReverseMatch at /admin/pages/new/blog/blogpage/7/ Reverse for 'wagtail_serve' with arguments '(u'blog//',)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['((?:[\w\-]+/)*)$']

每当我尝试根据 wagtail 演示创建新博文时，就会发生这种情况。我正在使用 Django 1.8.3

查看了此处的解决方案 https://groups.google.com/forum/#!msg/wagtail/RTzQyf8ec34/oOaupmu7rkUJ 我可以确认 wagtail 网址已包含在我的 urls.py 文件中

这是我的 models.py 文件

Answer 1

问题出在这里：

BlogPage.promote_panels = [
    FieldPanel('tags'),
]

此处的 promote_panels 列表缺少基本页面 class 中的字段，例如页面 slug - 因此，您正在创建一个没有 slug 的页面，它没有有效 URL。这个定义应该是：

BlogPage.promote_panels = Page.promote_panels + [
    FieldPanel('tags'),
]
