Features

Logger Setup

The Logger class provides a custom logging functionality with various log levels and output options. It is imported from the alphaz_next.utils.logger module.

Initialization

The Logger class is initialized with the following parameters:

• name (str): The name of the logger.
• directory (str): The directory where the log files will be stored.
• level (int, optional): The log level. Defaults to logging.INFO.
• stream_output (bool, optional): If set to True, the logs will also be output to the console. Defaults to True.
• when (str, optional): Specifies when to rotate the log file. Defaults to "midnight".
• interval (int, optional): The interval at which the log file should be rotated. Defaults to 1.
• backup_count (int, optional): The number of backup log files to keep. Defaults to 10.
• file_name (str, optional): The name of the log file. If not provided, the log file will be named after the logger. Defaults to None.
• logging_formatter (str, optional): The format string for the log messages. Defaults to DEFAULT_FORMAT.
• date_formatter (str, optional): The format string for the date in the log messages. Defaults to DEFAULT_DATE_FORMAT.

Usage

Here's an example of how to use the Logger class:

from alphaz_next.utils.logger import Logger

logger = Logger(
    name="my_logger",
    directory="/path/to/log/files",
    level=logging.INFO,
    stream_output=True,
    when="midnight",
    interval=1,
    backup_count=10,
    file_name=None,
    logging_formatter=DEFAULT_FORMAT,
    date_formatter=DEFAULT_DATE_FORMAT
)

logger.info("This is an info log message.")

Database Connection Setup

The Database class represents a database connection and provides methods for various database operations.

Initialization

The Database class is initialized with the following parameters:

• databases_config (_DataBaseConfigTypedDict): A dictionary containing the configuration for the databases.
• logger (Logger): The logger object to be used for logging.
• base (DeclarativeMeta): The base class for the declarative models.
• metadata_views (List[MetaData] | None, optional): A list of metadata views. Defaults to None.

Usage

Here's an example of how to use the DataBase class:

from alphaz_next import DataBase, Logger

# Initialize the logger
logger = Logger(
    name='sqlalchemy.engine', 
    file_name="database", 
    stream_output=False, 
    level=logging.DEBUG
)

# Create the database configuration
databases_config = {
    "mydb1": {
        "host": "srv-mydb1-db-dev.example.com",
        "password": "MyDB1Dev_123",
        "username": "mydb1adm",
        "port": 1234,
        "driver": "oracledb",
        "service_name": "mydb1",
        "ini": false
    },
    "mydb2": {
        "path": "{{project}}/mydb2.sqlite",
        "driver": "sqlite",
        "ini": true,
        "init_database_dir_json": "{{project}}/tests/mydb2/ini",
        "connect_args": {
            "check_same_thread": false
        }
    }
}

# Initialize the database connection
database = DataBase(
    databases_config=databases_config, 
    logger=logger, 
    base=Base
)

# Use the database connection
with database.session_factory() as session:
    # Perform database operations...
