Installation

1. Create a virtual environment, install dependencies, create a database:
   python -m venv .venv
pip install -r requirements.txt
docker-compose -f docker-compose-local.yaml up -d

2. Creating and applying migrations:
   Create an alembic base:
   alembic init migrations
   **Change the path to the database in the alembic file (alembic.ini): **
   sqlalchemy.url = postgresql://postgres:postgres@0.0.0.0:5432/postgres
   Import models into env .py
   from main import Base
target_metadata = Base.metadata
   Create the first migration
   alembic revision --autogenerate -m "comment"
   Apply migrations:
   alembic upgrade heads

3. Project start:
   uvicorn main:app --port 8000 --reload
