The Works

Flask commands

Execute commands with python -m flask --app the_works <command>

Available commands:

run: Serve app (don't use for production).

shell: start a shell within the app context (I can i.e. import specific table models and test the data structures returned by ORM methods like select())

Other useful stuff

Export database schema

Method 1: sqlite3 the_works.sqlite .schema > outputfile.sql

Method 2: Open DB in SQLitebrowser and use File -> Export -> Database to SQL file …

keep original CREATE statements
export schema only
overwrite old schema (DROP TABLE, then CREATE TABLE)

Generate declarative SQLAlchemy code

Right now the_works reflects an existing database in order to infer the underlying data models for SQLAlchemy. If I wanted to declare the data models directly instead of using reflection, I would need declarative code. This code can be generated from an existing database with the help of sqlacodegen:

sqlacodegen sqlite:///path/to/db.sqlite > outputfile.py

Generate `requirements.txt`

I use pipreqs to generate the file requirements.txt. The package scans all source files for import statements and uses those to extract all required Pip packages.
