anduin 7.0.21

a lite mysql & sqlite3 connect engine, mapping table into k-v structure

a lite mysql & sqlite3 connect engine… Name from the Lord of Ring

<=========how to use=========>

from anduin.river import Ring

configuration setting:

db_config = {‘host’: mysql host,

‘user’: username,

‘password’: password,

‘database’: database name,

‘port’: port,

‘engine’:’mysql’}

then use Ring.init(db_config) to init the connection

now enjoy it!!

or you can put a config file in config/db_config.py , write the dict in it

cond = [

(col1,’=’,val1), (col2,’=’,val2), ….]

fields = [

col1, col2 …]

params = {

key1:val1, key2:val2, …}

find one line of data:

Ring.find(__TableName__,conditions=cond,fields=fields)

return a python dict like { col1:value1,col2:value2…}

find datas

Ring.select(__TableName__,conditions=cond,fields=fields)

return a python list like [{ col1:value1,col2:value2…}]

update data:

Ring.update(__TableName__,conditions=cond,params=params)

return None

insert data:

Ring.insert(__TableName__,params=params)

return None

delete data:

Ring.delete(__TableName__,conditions=cond)

return None

using Ring.query() to execute sql directly like Ring.query(‘select * from table’)

all of these executions will have auto commit

or you can do like

from anduin.river import Ring

db_manager = Ring.Base_pool[‘default’] sql = db_manager.find_free_sql()

sql.update(‘user’,cond,or_cond=None,params=params ) sql.insert(‘user’,params=params ) sql.delete(‘user’,cond,or_cond=None)

sql.commit()

to choose a certain sql connection to execute
