Python Django 1.7-makemigrations未检测到更改-托管模型

我刚刚在虚拟环境中安装了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

因此，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'

然后我尝试运行makemigrations，但它说没有检测到任何更改

$ django-admin makemigrations

在我所有的模型中，我都有

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

我可能缺少什么？

您需要首先运行

migrate

命令来构建数据库架构。然后，您可以为每个应用程序运行

makemigrations

。查看以了解更多信息。

确保更新models.py文件以实际导入模型。例如，在models.py中，您可以从service_bus.models.academy import*获得

。manage脚本遍历该文件，导入acquisition.py中的所有模型，并检测其中的更改。如果未将新模型添加到models.py，则管理脚本将不知道模型文件中的新模型
