Hello,
I'd appreciate your suggestions for a better approach to the following task.
I have 2 files ( 2 classes). One (ClassA) has all logic related to the main
workflow of the program. Another (DB), I like to offload all operations with a
DB ( sql3 in this case).
I'm trying to pass the connection to the main class, but having problems. One
of them, is i can't pass the conn as a parameter to the function in one
(ClassA.abc()), because i inherit it ( function abc() ).
I created a self.DBConnection field, but i'm not sure if i'm on the right
path...
Code is gutted to highlight the problem.
Thank you

one.py:
from .DB import *
class ClassA(OtherObject):
def __init__(self):
self.DBConnection = sql3.Connection
def abc(self, reqId: int):
DB.writeTicks(self,self.DBConnection,reqId))
DB.py:
import sqlite3 as sql3
import sys
from .tws import TWS
from utils import current_fn_name
class DB(object):
db_location = ''
# db_location = '../DB/pairs.db'
def __init__(self, location='../DB/pairs.db'):
db_location = location
print(current_fn_name(),' self.db_location =
{}'.format(db_location))
try:
with open(db_location) as file:
pass
except IOError as e:
print("Unable to locate the Db @
{}".format(db_location))
def reqConnection(self):
try:
con = sql3.connect(self.db_location)
con.text_factory = str
except sql3.Error as e:
print("Error %s:".format( e.args[0]))
sys.exit(1)
return con
def write(self, con : sql3.Connection, tickId: int):
con.execute( blah)
