一个简单的ModelAdmin示例的TemplateDoesNotExist错误

Question

我在ModelAdmin其他几个项目中使用了Wagtail ,取得了巨大的成功,但这是我第一次尝试将它与继承的模型一起使用Page.

我复制了简单的示例模板并删除了与我无关的部分BlogPageModel.

链接ModelAdmin显示为预期,但当我点击它,我得到TemplateDoesNotExist at /admin/blog/blogpage/.

我不记得以前要设置模板了.我缺少一个设置吗？

Wagtail:1.9/Django:1.10.5/Python:3.5.2

更新:我尝试了一个继承自models.Model同样结果的模型.

跟踪如下:

我怀疑你已经错过了加'wagtail.contrib.modeladmin'来INSTALLED_APPS.
