Logger Decorator

Logger Decorator can log sync/async/yield (sync/async) functions. 

Can pass unique request id for all functions to have possibility ease find in your log all operations by filtering request_id.

Use as simple python decorator

if you need alerting to slack you can use @LoggerDecorator intead of @logger_decorator
@LoggerDecorator(
    event_type='main_func',
    full_trace=True,
    webhook_url=<you_url>',
    entry=True,
    notification_slack=True
    )

Getting started

1. pip install logger_decorator
1.1 import: from logger_decorator import logger_decorator
1.2 If function return yield need to pass yield_=True
1.3 Decorator need to be placed last
1.4 To generate unique request_id  you need use  middleware

Example middleware usage (Fast Api)

@app.middleware("http")
    async def log_request(request: Request, call_next):
        set_request_id() # to create unique request_id
        response: responses.StreamingResponse = await call_next(request)
        return response

Usage with Threads to pass request_id

1. To pass request_id use <kwargs> kwargs = {'request_id': get_request_id_()}

To use with Celery and pass request_id from your app to celery

celery_task.apply_async(args=(ar,), kwargs={'request_id': get_request_id_()})

Usage with celery Beat

       celery.conf.beat_schedule = {
           'call-every-10-seconds': {
           'task': 'my_schedule_task',
           'schedule': 10.0, #time-interval type
       }
    
       @logger_decorator(event_type='task1')
       def task1(*args, **kwargs):
           pass
    
       @logger_decorator(event_type='task2')
       def task2(*args, **kwargs):
           pass
    

    @celery.task(name='my_schedule_task') 
    def my_schedule_task(*args, **kwargs):
        set_request_id() # create request_id
        task1(request_id=get_request_id_())
        task2(request_id=get_request_id_())

Usage with Django

<middlewary.py>
from logger_decorator import set_request_id

class MyMiddleware:
    def __init__(self, get_response):
        set_request_id() # initializations request_id
        self._get_response = get_response

    def __call__(self, request):
        response = self._get_response(request)
        set_request_id() # initializations request_id
        return response

<serializers.py>
from rest_framework import serializers
from main.models import Book
from logger_decorator import logger_decorator

@logger_decorator(event_type='helper_func')
def helper_func():
    return 'ok'


class BookModelSerializer(serializers.ModelSerializer):

    title = serializers.SerializerMethodField()

    @logger_decorator(event_type='get_title')
    def get_title(self, obj):
        helper_func()
        return obj.title

    class Meta:
        model = Book
        fields = '__all__'
