Django数据库迁移优化(目前只完善MySQL)
主要功能
-
支持写入表注释及字段注释
-
支持写入字段默认值
-
常用字段数据模型基类
django_kelove_db.abstract_models
使用示例
-
修改django配置文件 ENGINE 为 django_kelove_db.backends.mysql
-
配置
INCLUDE_DEFAULT
(可选),示例如下
DATABASES = {
'default': {
'ENGINE': 'django_kelove_db.backends.mysql',
'NAME': 'django_kelove',
'USER': 'django_kelove',
'PASSWORD': 'django_kelove',
'HOST': '127.0.0.1',
'PORT': 3306,
'INCLUDE_DEFAULT': lambda model, field, include_default, connection: False if field.db_parameters(
connection=connection
)['type'] in ['longtext', 'longblob'] else True
}
}
KELOVE_DATABASES = {
'FOREIGN_DELETE_TYPE': 'django.db.models.deletion.PROTECT',
'DB_CONSTRAINT': False,
'DB_CONSTRAINT_USER': False,
'STATUS_CHOICES': [(-1, '草稿'), (0, '待审'), (1, '通过'), (2, '驳回')],
'DOC_TITLE': '数据库设计文档'
}
- 使用数据库文档功能时,需要将应用添加到
INSTALLED_APPS
,并添加路由
INSTALLED_APPS = [
...
'django_kelove_db.apps.DjangoKeloveDbConfig',
...
]
from django.conf.urls import url
from django.urls import include
urlpatterns = [
...
url(r'doc/', include('django_kelove_db.urls')),
...
]
