wagtail - 一个简单的 ModelAdmin 示例的 TemplateDoesNotExist 错误

Question

我用过 Wagtail 的 ModelAdmin在其他一些项目上取得了巨大的成功，但这是我第一次尝试将它与继承自 Page 的模型一起使用.

我复制了simple example模板并删除了与我的 BlogPageModel 无关的部分.
ModelAdmin的链接按预期显示，但是当我单击它时，我得到 TemplateDoesNotExist at /admin/blog/blogpage/ .

我不记得以前必须设置模板。有没有我缺少的设置？

鹡鸰:1.9/
Django :1.10.5/
python :3.5.2

更新:我使用继承自 models.Model 的模型进行了尝试。以及相同的结果。

追溯如下:

我怀疑你错过了添加 'wagtail.contrib.modeladmin'至INSTALLED_APPS .
