我收到以下错误，无法确定错误的位置
NoReverseMatch at / admin / pages / new / blog / blogpage / 7 / Reverse for ＆＃39; wagtail_serve＆＃39;有论据＆＃39;（你＆＃39;博客//＆＃39;，）＆＃39;和关键字参数 ＆＃39; {}＆＃39;未找到。尝试了1种模式：[＆＃39;（（？：[\ w \ - ] + /）*）$＆＃39;]
每当我尝试根据wagtail演示创建新的博客帖子时，就会发生这种情况。我正在使用django 1.8.3
在这里查看解决方案https://groups.google.com/forum/#!msg/wagtail/RTzQyf8ec34/oOaupmu7rkUJ我可以确认我的urls.py文件中包含了wagtail网址
这是我的models.py文件

答案 0 :(得分：1)
问题在于：
BlogPage.promote_panels = [
FieldPanel('tags'),
]
此处的promote_panels列表缺少基本Page类中的字段，例如页面slug - 因此，您创建的页面没有slug，该页面没有有效的URL。这个定义应该是：
BlogPage.promote_panels = Page.promote_panels + [
FieldPanel('tags'),
]
