# rdmysql3: A simple db layer based on CyMysql for Python 3.x
## Installation
pip install [--no-deps] rdmysql3
## Usage:
``` python
from datetime import datetime, date
from rdmysql3 import (Database, Table, Daily,
Row, Expr, And, Or, iter_query_daily)
import settings
Database.configures.update(settings.MYSQL_CONFS)
class UserProfile(Table):
__dbkey__ = 'user'
__tablename__ = 't_user_profiles'
__indexes__ = ['username']
class UserEvent(Daily):
__dbkey__ = "default"
__tablename__ = "t_user_events"
query = UserProfile().filter_by(username = 'ryan')
ryan = query.one(model = Row)
if ryan:
print ryan.to_dict()
now = datetime.now()
today = now.strftime('%Y%m%d')
ryan['changed_at'] = now.strftime('%Y-%m-%d %H:%M:%S')
ryan.change('nickname', 'Ryan-%s' % today)
query.save(ryan)
print(query.db.sqls)
def get_all_logins(model):
q = model.filter_by(category="login").order_by("id", "DESC")
return q.all(model=Row, reset=True)
query = UserEvent()
rows = iter_query_daily(query, get_all_logins,
stop=date(2024,3,1), fuse=True)
print(query.db.sqls)
```
## Methods of Table
There are some methods for class named 'Table':
insert param *rows
param **kwargs
delete param **where
update param changes : dict
param **where
save param changes : dict / object
param indexes : list (optional default=[])
filter param expr : Expr / str
param *args
filter_by param **where
order_by param field : str
param direction : 'ASC' / 'DESC' (optional default='ASC')
group_by param field : str
all param coulmns : str (optional default='*')
param limit : int (optional default=0)
param offset : int (optional default=0)
one param coulmns : str (optional default='*')
param model : class (optional default=dict)
apply param name : str
param *args
param **kwargs
count,sum,max,min,avg param *args
param **kwargs
## Methods of Monthly/Weekly/Daily
Monthly is a subclass of Table, There are other two methods for Monthly:
backward param monthes : int (optional default=1)
forward param monthes : int (optional default=1)
set_date param curr_date : date
migrate param prev_date : date (When curr_has_suffix is False)
