Question

我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

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

然后我做了，在bash：

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
System check identified some issues:

WARNINGS:

在我的所有模特中，我都有类似

的东西

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

我能错过什么？

Answer 1

首先需要运行migrate命令来构建数据库模式。然后，您可以为每个应用运行makemigrations。有关详细信息，请查看Django tutorial。

Answer 2

确保更新models.py文件以实际导入模型。例如，在models.py中，您有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，则管理脚本不会了解模型文件中的新模型。

Django 1.7 - makemigrations没有检测到变化 - 托管模型
