A storm folk for canonical storm project

storm-orm

该项目的来源是 https://storm.canonical.com/Tutorial , 一个Python的ORM框架,本项目基于 storm 0.20 进行的修改, 遵循LGPL 2.1, 这也是storm本身的开源许可

添加了如下功能

1. store.raw_execute
2. Resulset.fetchall
3. Resultset.fetchone
4. Resulset.get_select_sql

目的:

1. 可以继续使用 Storm 的表达式构造查询, 通过 raw_execute方法执行SQL语句, 可以使用异步的驱动完成后面的查询

    class User(object):
        __storm_table__ = "user"
        user_id = Int(primary=True)
        username = Unicode()
        age = Int()


    sql, param = store.find(User, User.username==u'alex').get_select_sql()
    ...
    cursor = connection.cursor()
    cursor.execute(sql, param)
    for row in cursor.fetchall():
        #do something on row
        pass
    

修改了PropertyPublisherMeta这个元类, 要求在 Model 使用 str 引用其他模型时，必须在模型中声明 refybname = True ,在如下情况下可以使用, 目的是节省内存, 具体可以看 https://github.com/alex8224/storm-orm/blob/master/storm/properties.py#L334

from storm.locals import Storm

class BaseModel(Storm): pass

class User(BaseModel):
    __storm_table__ = "user"
    __refbyname__ = True
    user_id = Int(primary=True)
    username = Unicode()
    age = Int()


class UserDetail(BaseModel):
    __storm_table__ = "user_detail"
    __refbyname__ = True
    user_id = Int(primary=True)
    user = Reference(user_id, "User.id")
