Export Baikal addressbook using Python 3

README.md

This script loads an addressbook from a Baikal SQLite database file using SQLAlchemy, and writes the contacts to a single baikal.vcf file.

Install dependencies:

pip3 install SQLAlchemy vobject

baikal_export.py

from pathlib import Path

import vobject
from sqlalchemy import create_engine

CARDS = 'cards'


class BaikalDatabase(object):
    cards = []
    db_engine = None

    def __init__(self, username='', password='', dbname=''):
        engine_url = f'sqlite:///{dbname}'
        self.db_engine = create_engine(engine_url)

    def export_cards(self, table='', query=''):
        with self.db_engine.connect() as connection:
            try:
                self.cards = []
                result = connection.execute(query)
            except Exception as e:
                print(e)
            else:
                for row in result:
                    self.cards.append(vobject.readOne(row[1]))
                result.close()

    def export(self):
        query = "SELECT id, carddata FROM {TBL_CARDS} WHERE " \
                "addressbookid LIKE '1';".format(TBL_CARDS=CARDS)
        self.export_cards(query=query)


def main():
    # read cards
    dbms = BaikalDatabase(dbname='db.sqlite')
    dbms.export()

    # save cards to single file
    cfile = Path('baikal.vcf')
    cfile.touch()
    with cfile.open('w') as f:
        for card in dbms.cards:
            card.prettyPrint()
            f.write(card.serialize())

    print(f"Total cards: {len(dbms.cards)}")
