 Available commands:
 
 * `run`: Serve app (don't use for production).
-* `init-db`: Create empty SQLite database `works.sqlite` in project root. BE CAREFUL: If a database already exists, it will be deleted with everything in it.

+* `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](https://pypi.org/project/sqlacodegen/):
+
+`sqlacodegen sqlite:///path/to/db.sqlite > outputfile.py`
+
+
+### Generate `requirements.txt`
+
+I use [pipreqs](https://pypi.org/project/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.
