企业级Django数据治理框架
在企业级Django应用开发中，数据治理是确保系统稳定性和可维护性的关键。本文将介绍一个完整的数据治理框架实现。
核心组件
首先创建数据治理模型：
# models.py
from django.db import models
from django.contrib.auth.models import User
class DataAsset(models.Model):
name = models.CharField(max_length=200)
description = models.TextField()
owner = models.ForeignKey(User, on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
is_active = models.BooleanField(default=True)
class Meta:
permissions = [
('can_view_data_asset', 'Can view data asset'),
('can_manage_data_asset', 'Can manage data asset'),
]
# 管理数据变更日志
class DataChangeLog(models.Model):
ACTION_CHOICES = [
('create', 'Create'),
('update', 'Update'),
('delete', 'Delete'),
]
asset = models.ForeignKey(DataAsset, on_delete=models.CASCADE)
action = models.CharField(max_length=20, choices=ACTION_CHOICES)
user = models.ForeignKey(User, on_delete=models.CASCADE)
old_data = models.JSONField(blank=True, null=True)
new_data = models.JSONField(blank=True, null=True)
timestamp = models.DateTimeField(auto_now_add=True)
数据治理中间件
# middleware.py
class DataGovernanceMiddleware:
def __init__(self, get_response):
self.get_response = get_response
def __call__(self, request):
response = self.get_response(request)
# 记录API调用日志
if hasattr(request, 'data_asset') and request.method in ['POST', 'PUT', 'DELETE']:
self.log_data_change(request)
return response
def log_data_change(self, request):
# 实现数据变更记录逻辑
pass
配置与使用
- 在
settings.py中添加配置：
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'your_app.middleware.DataGovernanceMiddleware',
# ...其他中间件
]
INSTALLED_APPS = [
'your_app.apps.YourAppConfig',
'django.contrib.auth',
'django.contrib.contenttypes',
# ...其他应用
]
- 执行数据迁移：
python manage.py makemigrations
python manage.py migrate
这个框架确保了数据变更的可追溯性，为企业的数据合规和审计提供了坚实基础。
