Development SQL Scripts

Drop all tables for POSTGRES

DO $$ DECLARE
    r RECORD;
BEGIN
    -- if the schema you operate on is not "current", you will want to
    -- replace current_schema() in query with 'schematodeletetablesfrom'
    -- *and* update the generate 'DROP...' accordingly.
    FOR r IN (SELECT tablename FROM pg_tables WHERE schemaname = current_schema()) LOOP
        RAISE NOTICE 'Dropping table: %', r.tablename;
        EXECUTE 'DROP TABLE IF EXISTS ' || quote_ident(r.tablename) || ' CASCADE';
    END LOOP;
END $$;

Database Migration

We use Alembic for database migration. Here are the steps to create and apply database migrations:

1. Initialize Alembic

   If you haven't already, initialize Alembic in your project:

   make alembic-init

   This will create a new directory named alembic in your project root, which contains your migration scripts.

2. Create a New Migration

   After you've made changes to your SQLAlchemy models, you can create a new migration script with:

   make alembic-rev

   You'll be prompted to enter a name for the migration. This name should describe the changes you've made.

3. Apply Migrations

   To apply the migrations to your database, run:

   make alembic-migrate

   This will upgrade your database to the latest version.

4. Downgrade Database

   If you need to downgrade your database to a previous version, you can use:

   make alembic-downgrade

   You'll be prompted to enter the name of the revision to downgrade to.

Remember to commit your migration scripts to version control along with the corresponding changes to your models.
