我刚刚在我的虚拟环境中安装了 django 1.7。

然后我手动创建了以下文件：

service_bus/
service_bus/__init__.py
service_bus/django_settings.py
service_bus/models
service_bus/models/__init__.py
service_bus/models/dsp.py
service_bus/models/audience_type.py
service_bus/models/category.py
service_bus/models/audience.py
service_bus/models/dsp_config.py
service_bus/models/apsettings.py

所以我有一个设置文件service_bus/django_settings.py和service_bus应用程序。

然后我在bash上做了：

export DJANGO_SETTINGS_MODULE='service_bus.django_settings'

然后我只是尝试运行 makemigrations，但它说没有检测到任何更改。

$ django-admin makemigrations
Loading properties from /etc/s1mbi0se/dmp.ini

No changes detected in app 'service_bus'

在我所有的模型中，我都有类似的东西

class APSettings(models.Model):
    ...
    class Meta:
        db_table = u'APSettings'
        app_label = 'service_bus'

我会错过什么？

您需要先运行该migrate命令来搭建数据库架构。然后，您可以makemigrations为每个应用程序运行。查看Django 教程以获取更多信息。

确保更新您的 models.py 文件以实际导入模型。例如在 models.py 你会有 from service_bus.models.audience import *. 管理脚本遍历该文件，导入 Audience.py 中的所有模型并检测其中的更改。如果您没有将新模型添加到 models.py，那么管理脚本将不会知道模型文件中的新模型。
