Notice: Most of this will be moved into a wiki.

What is Django-Automated-Logging (DAL)?

TL;DR: DAL is a package to automatically track changes in your project, ranging from simple logging messages, to model changes or requests done by users.

You can decide what you want to do and how. DAL allows fine-grained customization and filtering with various methods.

Introduction

Django Fully Automated Logging - finally solved and done properly.

How to install? pip install django-automated-logging or poetry add django-automated-logging

What is the purpose?

The goal of DAL is to provide an easy, accessible and DRY way to log the inner working of you applications. Ultimately giving you the chance to easily see what is happening without excessive manual print/logging statements.

The application uses minimal requirements and is performant.

How does it work?

The application facilitates the built-in logging mechanic by providing a custom handler, that just needs to be added to the LOGGING configuration.

DAL uses native Django signals to know what is happening behind the scenes without injecting custom code.

Minimal Setup

You can also configure DAL to only log to a file and not to a database. You just need to enable DAL and not include the custom logging handler.

Detailed Information

Features

  1. Easy Setup
  2. Extensible
  3. Feature-Rich
  4. Completely Automated
  5. Built-In Database Logger
  6. No custom code needs to be inserted into your codebase
  7. Can capture logging messages unrelated to the package itself
  8. Only does what it needs to do, no extra bells and whistles.

Setup

Initial Configuration is via your projects settings.py

  1. INSTALLED_APPS append: 'automated_logging'
  2. MIDDLEWARE append: 'automated_logging.middleware.AutomatedLoggingMiddleware'
  3. LOGGING section handlers add:
       'db': {
           'level': 'INFO',
           'class': 'automated_logging.handlers.DatabaseHandler',
       {
  4. LOGGING section loggers add: (only required if database logging desired)
       'automated_logging': {
           'level': 'INFO',
           'handlers': ['db'],
           'propagate': True,
       },
       'django': {
           'level': 'INFO',
           'handlers': ['db'],
           'propagate': True,
       },
  5. execute: python manage.py migrate automated_logging

LOGGING configuration details are just recommendations.

Configuration

Further configuration can be done via the variable AUTOMATED_LOGGING. The defaults are:

AUTOMATED_LOGGING = {
    "globals": {
        "exclude": {
            "applications": [
                "plain:contenttypes",
                "plain:admin",
                "plain:basehttp",
                "glob:session*",
                "plain:migrations",
            ]
        }
    },
    "model": {
        "detailed_message": True,
        "exclude": {"applications": [], "fields": [], "models": [], "unknown": False},
        "loglevel": 20,
        "mask": [],
        "max_age": None,
        "performance": False,
        "snapshot": False,
        "user_mirror": False,
    },
    "modules": ["request", "unspecified", "model"],
    "request": {
        "data": {
            "content_types": ["application/json"],
            "enabled": [],
            "ignore": [],
            "mask": ["password"],
            "query": False,
        },
        "exclude": {
            "applications": [],
            "methods": ["GET"],
            "status": [200],
            "unknown": False,
        },
        "ip": True,
        "loglevel": 20,
        "max_age": None,
    },
    "unspecified": {
        "exclude": {"applications": [], "files": [], "unknown": False},
        "loglevel": 20,
        "max_age": None,
    },
}

You can always inspect the current default configuration by doing:

from pprint import pprint
from automated_logging.settings import default
from automated_logging.helpers import namedtuple2dict

pprint(namedtuple2dict(default))

Recommendation: include the globals application defaults as those modules can be particularly verbose or be duplicates.

There are three different independent modules available request (for request logging), unspecified (for general logging messages), and models (for model changes). They can be enabled and disabled by including them in the modules configuration.

The loglevel setting indicates the severity for the logging messages sent from the module. INFO (20) or DEBUG (10) is the right call for most cases.

New in 6.x.x: Saving can be batched via the batch setting for the handler.

New in 6.x.x: Saving can be threaded by thread: True for the handler settings. This is highly experimental

New in 6.x.x: every field in exclude can be either be a glob (prefixing the string with gl:), a regex (prefixing the string with re:) or plain (prefixing the string with pl:). The default is glob.

Decorators

You can explicitly exclude or include views/models, by using the new decorators.

from automated_logging.decorators import include_view, include_model, exclude_view, exclude_model

@include_view(methods=None)
@exclude_view(methods=[])
def view(request):
    pass

@include_model(operations=None, fields=None)
@exclude_model(operations=[], fields=[])
class ExampleModel:
    pass

include always takes precedence over exclude, if you use multiple include or exclude instead of overwriting they will update/extend the previous definition.

operations can be either create, modify, delete. fields is a list model specific fields to be included/excluded. methods is a list methods to be included/excluded.

Class-Based Configuration

Class-Based Configuration is done over a specific meta class LoggingIgnore. Decorators take precedence over class-based configuration, but class-based configuration takes precedence over AUTOMATED_LOGGING configuration.

class ExampleModel:
    class LoggingIgnore:
        complete = False
        fields = []
        operations = []

as described above operations and fields work the same way. complete = True means that a model is excluded no matter what.
