django谷歌应用引擎错误

Question

我对 django 开发完全陌生，由于公司的一些要求，我正在尝试使用谷歌应用引擎。我在尝试执行 manage.py syncdb 时遇到此错误。

错误：没有名为 appengine_django 的模块

这是我的文件： 设置.py

Answer 1

在 AppEngine 中使用 Django 时，您应该使用 Django-nonrel。 Google introduction.

您似乎正在尝试使用无法解析的名为 appengine_django 的 django 应用程序。你安装了吗？你是怎么安装的？

此链接可能会帮助您获得最近的完整 django 实现： http://allbuttonspressed.com 不过，您可能无需修补所有 django 就可以实现您想要的。只需尝试手册中的一个示例并在其上构建，一些不包括的 django 东西是表单预览、插件、扩展，但 django 模板系统是 GAE 内置的，所以我首先分析一下你的项目是否真的需要完整的 django 或者可以使用我使用的东西，即 Jinja2 + WTFOrms + python 2.7 GAE = 我的堆栈。
