天智信达的库

用法

1. 此库作为git项目管理，凡是修改完后应及时通知到开发团队
2. 需要使用库中的方法，使用pip install,这时候就可以在项目中引用库中的方法
3. 引用的方法举例：

---

• generation - 更新库

Make sure you installed setuptools and wheel.

Important: You must modify the version of the package in setup.py and delete folders (build, dist, egg-info)

python setup.py sdist bdist_wheel

• upload - 上传代码

Install twine before doing this(qays:鱼和熊掌不可兼得）

twine upload dist/*

---

• install - 安装

pip install wisdoms

• find the latest package of wisdoms - 发现最新版本

pip list --outdated

• upgrade - 升级到最新包

pip install wisdoms --upgrade

packets usage:

• auth.py:

    # 权限验证
    from wisdoms.auth import permit

    host ={'AMQP_URI': "amqp://guest:guest@localhost"}

    auth = permit(host)

    class A:
        @auth
        def func():
            pass

• config.py

    # 读取yml配置
    from wisdoms.config import c

    # gains item of YML config
    print(c.get('name'))

    # transforms class into dict
    d = c.to_dict()
    print(d['name'])

• commons package

    # 返回执行后的状态码
    from wisdoms.commons import revert, codes, success

    def func():
        # do something

        # revert(codes.code) or revert(number)
        # return revert(1)
        return revert(codes.ERROR)

    def foo():
        # return revert(code, data, desc)
        return revert(codes.SUCCESS, {'data':'data'},'返回成功描述信息')

    def done():
        # simplified revert where success execute
        # return success(data) or success()
        return success()

• util.py

    # 多个字符串连接成路径
    from wisdoms.utils import joint4path

    print(joint4path('abc','dac','ccc'))

    # $: abc/dac/ccc

    # ------------------------------------------------------------------
    # 对象转字典
    from wisdoms.utils import o2d

    o2d(obj)

    # ------------------------------------------------------------------
    # 捕获异常装饰器
    from wisdoms.utils import func_exception

    ex = func_exception(codes.WARNING)

    @ex
    def func():
        pass


    # ------------------------------------------------------------------
    # 捕获异常类装饰器
    from wisdoms.utils import cls_exception

    # ex为方法装饰器
    xpt_cls = cls_exception(ex)

    @xpt_cls
    class A:
        name = 'a'

        def __init__(self, param):
            self.desc = param

        def func1(self, param):
            return self.desc + param

        @classmethod
        def func2(cls, param):
            print(cls)
            print('func2', param)
            raise Exception('func2 error')

        @staticmethod
        def func3(param):
            print('func3', param)
            raise Exception('func3 error')

    aa = A('param')
    # 注意： 该装饰器的静态方法和类方法必须用实例调用
    print(aa.func1('1111111'))
    print(aa.func2('2222222'))
    print(aa.func3('3333333'))

• ms.py

    from wisdoms.ms import ms_base

    MsBase = ms_base(config)

    class A(MsBase):
        pass

    # -----------------------------------------------
    from wisdoms.ms import closure_crf

    crf = closure_crf(config('ms_host'))

• pg_db.py

    from wisdoms.pg_db import session_exception

    se = session_exception(session)

    @se
    def func():    
        # raise exception extend SqlalChemyError
        pass

    # ------------------------------------------------------------------
    # session 增删改查表基础类，已经实现增删改查通用方法，直接继承就能使用
    from wisdoms.db import repo_ref

    RepoBase = repo_ref(session)

    class FooRepo(RepoBase):
        """
        common add, delete, update, get(include search) function finished
        """
        pass

    # Foo is the model of table
    foo = FooRepo(Foo)

    # you can do follow list
    foo.add({'name':'name','desc':'desc',...})
    foo.update(id,{'name':'rename','desc':'redesc',...})
    foo.delete(id)

    foo.get() # return list of all objects
    foo.get(id) # return a object
    foo.get(None,name ='name',...}) # return list of objects what you search

如何设计包

• 顶级包：wisdom，代表天智，智慧
• 现阶段的约定：采用一级包的方式
• 不同的功能放在不同的文件（模块）即可做好方法的分类
