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:一只会抓鱼的熊）

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pip list --outdated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:

• ms.py:

• 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

    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(name ='name',...) # return list of objects what you search


#-----------------------------------------------------



postgresql 使用ARRAYJSON
使用 jsonb 来存储
example: notes = Column(CastingArray())

class CastingArray(ARRAY):

    def bind_expression(self):
        return cast(JSONB, self)

#---------------------------------------------------------

定制PG model 五个基本属性
class BaseModelPG(declarative_base()):
    __abstract__ = True  

    # 定制基本属性
    id = Column(Integer, nullable=False, primary_key=True, unique=True, autoincrement=True, )
    uid = Column(Integer, nullable=False)
    oid = Column(Integer, nullable=False)
    create_time = Column(DateTime, default=datetime.now(), onupdate=datetime.now())
    update_time = Column(DateTime, default=datetime.now(), )


使用例子
class SomeEntity(BaseModelPG):
    name = models.CharField(max_length=1000)
    address = models.CharField(max_length=1000, default='')
    info = models.CharField(max_length=2000, default='')

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
