django初始化后一些常规重置工作

配置重置

1. 执行下面代码创建django的一个项目pt_edu:

django-admin startproject pt_edu

 

 

 

 

 2.创建config包文件夹,在config包文件夹下创建两个py文件,分别为develop.py和product.py:

 

 3.将下面的代码分别加入manage.py、asgi.py、wsgi.py替换:

# os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'pt_edu.settings')
# 可以通过 环境变量PROJECT_PROFILE为develop或者 product,让django 加载不同的配置
profile = os.environ.get('PROJECT_PROFILE', 'develop')
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'pt_edu.config.%s' % profile)

manage.py如下:

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys


def main():
    # os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'pt_edu.settings')
    # 可以通过 环境变量PROJECT_PROFILE为develop或者 product,让django 加载不同的配置
    profile = os.environ.get('PROJECT_PROFILE', 'develop')
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'pt_edu.config.%s' % profile)
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()

asgi.py如下:

"""
ASGI config for pt_edu project.

It exposes the ASGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/3.0/howto/deployment/asgi/
"""

import os

from django.core.asgi import get_asgi_application

# os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'pt_edu.settings')
# 可以通过 环境变量PROJECT_PROFILE为develop或者 product,让django 加载不同的配置
profile = os.environ.get('PROJECT_PROFILE', 'develop')
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'pt_edu.config.%s' % profile)

application = get_asgi_application()

wsgi.py如下:

"""
WSGI config for pt_edu project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/3.0/howto/deployment/wsgi/
"""

import os

from django.core.wsgi import get_wsgi_application

# os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'pt_edu.settings')
# 可以通过 环境变量PROJECT_PROFILE为develop或者 product,让django 加载不同的配置
profile = os.environ.get('PROJECT_PROFILE', 'develop')
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'pt_edu.config.%s' % profile)

application = get_wsgi_application()

4.测试环境默认加载 develop配置,生产环境需要设置环境变量进行启动:

[设置环境变量]
windows:  set PROJECT_PROFILE=product
PowerShell: $env:PROJECT_PROFILE="product"
linux: export PROJECT_PROFILE=product

5.develop.py配置参考如下:

from ..settings import *

DEBUG = True

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'django_db',
        'USER': 'root',
        'PASSWORD': '123456',
        'HOST': '127.0.0.1',
        'PORT': '3306',
    }
}

6.product.py配置参考如下(这个文件不能添加至git里面):

同develop.py就可以了。
