flask-logging-decorator

This is a deadly simple logging decorator for Flask. This is highly inspired by canassa/flask-trace.

Compatibility

This is tested with Python3.5, 3.6 and Flask1.0.2.

Installation

pip install flask-logging-decorator

Run the test

This modules uses pytest. You can install it before running the test.

python -m pytest -v

Usage

Import and put it as the decorator function.

import logging

from flask_logging_decorator import trace
from flask import Flask

app = Flask(__name__)

@trace(logging.ERROR)
@app.route('/')
def index():
    return 'hello'

...

The application should show the logging message like following.

[2018-05-17 19:01:31,468] ERROR in __init__: trace_uuid=cf66d343-06f4-49cb-a680-59ba9ec77570 method=GET func_name=index func_args: query_args:foo='bar' baz='qux' post_values: trace_info:trace_pathname=main.py trace_lineno=12

If you don't pass the logging level to @trace, it will use the Flask's application logger.
