一、文件目录格式
二、代码
1.conf.__init__.py
import importlib
import os
from conf import gsettings
class Settings(object):
def __init__(self):
#先加载全局配置
for item in dir(gsettings):
if item.isupper():
k=item
v=getattr(gsettings,k)
#给对象设置键值对
setattr(self,k,v)
#加载用户settings
setting_path=os.environ.get("SETTING")
settings_module=importlib.import_module(setting_path)
for s in dir(settings_module):
if s.isupper():
k=s
v=getattr(settings_module,k)
#给对象设置键值对
setattr(self,k,v)
settings=Settings()
2.gsettings.py
NAME='from system settings'
3.settings.py
NAME="from customer settings"
4.start.py
import os,sys
BASE_DIR=os.path.dirname(__file__)
sys.path.append(BASE_DIR)
# 设置一个全局的键值对
os.environ.setdefault('SETTING','lib.settings')
from conf import settings
print(settings.NAME)
