Question

我正在更改现有的应用程序，因此我可以扩展用例。我已经创建了一个新模型并更改了视图和模板。现在，我想运行迁移，但是我一直收到NameError信息，而Google搜索并没有为我提供更多信息，特别是因为我是在向正在运行的应用程序中添加内容而不是从头开始创建内容。有人可以帮助我吗？

我在admin.py中添加了以下行： admin.site.register（InputData）

错误：

编辑：我自己解决了。原来有一个“ init”文件，必须引用所有模型才能在Admin中使用它们。

Answer 1

这很可能意味着您没有在admin.py文件中导入“ InputData”。

Answer 2

错误的后两行告诉我，您可能忘记了在admin.py文件中导入“ InputData”类。

File "C:\var\www\SYSTEM\System\service_development\admin.py", line 201, in <module>
    admin.site.register(InputData)
NameError: name 'InputData' is not defined

在admin.py中导入“ InputData”类，您很高兴：）

Django NameError：名称“ model”未定义
