把django应用 打包 发布成 可独立运行的桌面程序

把django应用 打包 发布成 可独立运行的桌面程序

需求：在pc上运行django+sqlite应用，无须安装django python 数据库 web服务器 。。。

传统django 应用运行在 apache or nginx fastcgi，偽了方便我们用cherrypy来作WEB服务器。

cx_freeze 跨平台的python 打包工具

步骤：

1:下载安装
cx_freeze cherrypy

2 依赖关系 提前导入 项目依赖的包

import django.contrib.auth

import django.contrib.contenttypes

import django.contrib.sessions

import django.contrib.sites

import django.contrib.admin

#these pertain to your application

import subway.models

import subway.views

import urls

import manage

import settings

import django.db.models.sql.compiler

from django.contrib.auth.backends import *

from django.conf.urls.defaults import *

#these are django imports

import django.template.loaders.filesystem

import django.template.loaders.app_directories

import django.middleware.common

import django.contrib.sessions.middleware

import django.contrib.auth.middleware

import django.middleware.doc

import django.contrib.messages

import django.contrib.staticfiles

import django.contrib.messages.middleware

import django.contrib.sessions.backends.db

import django.contrib.messages.storage.user_messages

import django.db.backends.sqlite3.base

import django.db.backends.sqlite3.introspection

import django.db.backends.sqlite3.creation

import django.db.backends.sqlite3.client

import django.contrib.auth.context_processors

from django.core.context_processors import *

import django.contrib.messages.context_processors

import django.contrib.auth.models

import django.contrib.contenttypes.models

import django.contrib.sessions.models

import django.contrib.sites.models

import django.contrib.messages.models

import django.contrib.staticfiles.models

import django.contrib.admin.models

import django.template.defaulttags

import django.template.defaultfilters

import django.template.loader_tags

#dont need to import these pkgs

#need to know how to exclude them

import email.mime.audio

import email.mime.base

import email.mime.image

import email.mime.message

import email.mime.multipart

import email.mime.nonmultipart

import email.mime.text

import email.charset

import email.encoders

import email.errors

import email.feedparser

import email.generator

import email.header

import email.iterators

import email.message

import email.parser

import email.utils

import email.base64mime

import email.quoprimime

import django.core.cache.backends.locmem

import django.templatetags.i18n

import django.templatetags.future

import django.views.i18n

import django.core.context_processors

import django.template.defaulttags

import django.template.defaultfilters

import django.template.loader_tags

from django.conf.urls.defaults import *

import django.contrib.admin.views.main

import django.core.context_processors

import django.contrib.auth.views

import django.contrib.auth.backends

import django.views.static

import django.contrib.admin.templatetags.log

import django.contrib.admin.templatetags.adminmedia

import django.conf.urls.shortcut

import django.views.defaults

#let us hook up cherrypy

#is it possible to hook up the dev server itself?

import cherrypy

from cherrypy import wsgiserver

from django.core.handlers.wsgi import WSGIHandler

from django.core.servers.basehttp import AdminMediaHandler

from django.conf import settings

from django.utils import translation

3： 编写setup文件

from cx_Freeze import setup, Executable

import cx_imports

setup(

name = "ehome",

version = "1.0",

description = "the typical 'Hello, world!' script",

options = dict(build_exe = {'include_files': ['templates','media']}),#拷贝 admin的模板 资源文件

executables = [Executable("ehome.py")])

4： 替换 urls.py中 admin.autodiscover() 成

import django.contrib.auth.admin

#import django.contrib.contenttypes.admin

import django.contrib.sites.admin
否则 后台出现 无权限访问的提示

5： 启动服务

import cherrypy

from cherrypy import wsgiserver

from django.core.handlers.wsgi import WSGIHandler

from django.core.servers.basehttp import AdminMediaHandler

from django.conf import settings

from django.utils import translation

if __name__ == "__main__":

# django.core.management.base forces the locale to en-us. We should

# set it up correctly for the first request (particularly important

# in the "--noreload" case).

translation.activate(settings.LANGUAGE_CODE)

try:

path = './media'

handler = AdminMediaHandler(WSGIHandler(), path)

cherrypy.config.update({

'server.socket_host': 'localhost',

'server.socket_port': 8000,

'log.error_file': 'site.log',

'engine.autoreload_on': True

})

cherrypy.config.update({'environment': 'production',

'log.error_file': 'site.log',

'log.screen': False})

cherrypy.tree.graft(handler, '/')

cherrypy.engine.start()

cherrypy.engine.block()

finally:

cherrypy.engine.exit()

总结： 中间碰到好多问题

1：cx_freeze 文档很少

2：django 用了很多动态加载module的地方 都要手工 一一 import进来
