SQLAlchemy create engine with echo=True from config file - sqlalchemy

Question

I just want to know how to create the engine with the config file that would give the same result as:
engine = create_engine('sqlite:///mydb.sqlite', echo=True)
I think it would be with a config.py file like
DATABASE_URL = 'sqlite:///oracle.sqlite'
and
import config
from sqlalchemy import create_engine, engine_from_config
from sqlalchemy_utils.functions import database_exists, drop_database
engine = create_engine(config.DATABASE_URL, echo=True)
for creating the database every time it's needed. For deleting:
if database_exists(config.DATABASE_URL):
drop_database(engine.url)

Answer 1

config = {'db.url':'sqlite:///./somedb.db', 'db.echo':'True'}
engine = engine_from_config(config, prefix='db.')
You can have the config outside the file, and import it!
Also check this out, on SQLAlchemy Docs.

Answer 2

If you want to capture sql commands, see statistics, find slowest, check sqlalchemy-capture-sql (Disclaimer: I am the author of the package):
from sqlalchemy_capture_sql import CaptureSqlStatements
with CaptureSqlStatements(sqlalchemy_engine) as capture_stmts:
# put here calls to functions that issue sqlalchemy commands that
# produce some sql statements execution
session.add(user)
capture_stmts.pp()
the library will make full report, for instance:
============================================================
1. 0.0020 INSERT INTO users (name, fullname, nickname) VALUES (?, ?, ?)
<- 'joe+Joe Joey+joey'
2. 0.0009 SELECT FROM users WHERE users.id = ?
<- '2'
...
============================================================
== Slowest (top 5):
1. INSERT USERS 1 0.002 s INSERT INTO users (name, fullname, nickname) VALUES (?, ?, ?)
2. INSERT USERS 1 0.001 s INSERT INTO users (name, fullname, nickname) VALUES (?, ?, ?)
...
============================================================
