如何在应用程序之间共享模型？

Question

我的应用程序模型包含三个字段。第一个将与邮件应用程序共享，作为邮件目的地；第二个将与aps应用程序共享，作为页面显示的图形频率索引.html. 我想我已经很接近了，但是当我在终端中写入命令“runserver”时，它显示了以下错误：

"needs updating." % name django.core.exceptions.ImproperlyConfigured: Creating a ModelForm without either the 'fields' attribute or the 'exclude' attribute is prohibited; form ConfigurationFrorm needs updating.

这是我的密码，你知道我做错了什么吗？？你知道吗

正如错误消息所说，从django1.8开始，您需要使用fields或exclude类属性显式地告诉ConfigurationForm要包含哪些模型字段。如果需要所有字段，只需说fields = '__all__'。Django不再自动地假设这一点。你知道吗

您发布的代码中有几个缩进和拼写错误，这使您很难理解。避免这种情况的最好方法是复制并粘贴实际代码，而不是输入代码。你知道吗
