Description

Module for working with sql databases

Adding new functions to the library

To add default parameters when creating objects, you can add the default parameter to the object fields For example, for the exp_tabl table there is no point in specifying name every time, so let's add default to the name field: name = Column(String(256), nullable=False, default="exp_tabl name") now all exp_tabl will be created without the need to set this parameter. DO NOT USE VALUES FOR FIELDS THAT ARE NOT IDEMPOTENT

Example of work:

# settings.py
from db_contractor.db_connect import DBConnect
from db_contractor.entities_generator import EntitiesGenerator

db_connect = DBConnect(host="0.0.0.0", port="5432", db_name="db_name", username="user", password="pass", logger=logger)

# *.py
from db_contractor.processing_scheme import GlobalSetting, Match, Sport, Region, Competition
from settings import db_connect, entities_generator

# custom select
result_int = db_connect.get_one_result("SELECT id FROM table LIMIT 100")
result_list = db_connect.get_list_result("SELECT * FROM table LIMIT 100")
result_dict = db_connect.get_dict_result("SELECT * FROM table LIMIT 100")

#custom insert, delete, update
db_connect.session.execute("DELETE FROM table WHERE id = -100000")

Recommendations for work

It is recommended to initialize the object for working with the database once in the entire project, and then import the object itself.
