artemis-model

Welcome to artemis-model, the backbone repository that contains all the essential models used in both the artemis-api and the prophet project. This project includes asynchronous models used by artemis-api, such as Artist, and synchronous models like ArtistSync for other implementations.

Getting Started

To set up your development environment for artemis-model, follow these initial setup steps:

1. Environment Setup

cp ./alembic/.env.example ./alembic/.env

After copying the example environment file, make sure to fill in the .env file with your specific configurations.

2. Install Dependencies

poetry install --all-extras

This will install all necessary dependencies to get you started with artemis-models and alembic.

Creating a New Model

To introduce a new model in the project, you should start by creating a mixin and then define two different model classes that inherit from this mixin.

Example: Adding a LoginHistory Model

1. Define the Mixin This mixin will include all the common attributes of your model.

class LoginHistoryMixin:
    """
    Stores the login history of users.
    """

    id: Mapped[int] = mapped_column(primary_key=True, autoincrement=True, nullable=False)
    account_id: Mapped[uuid.UUID] = mapped_column(ForeignKey("user_account.id"), nullable=False, index=True)
    ip_address: Mapped[str] = mapped_column(nullable=True)
    created_at = mapped_column(DateTime, default=datetime.utcnow)

    @declared_attr
    def account(cls) -> Mapped["UserAccount"]:
        return relationship("UserAccount", back_populates="login_histories")

2. Inherit from Base Classes Create two classes that inherit from CustomBase and CustomSyncBase respectively, using the mixin for shared attributes.

class LoginHistorySync(CustomSyncBase, LoginHistoryMixin):
    pass

class LoginHistory(CustomBase, LoginHistoryMixin):
    pass

Version Management and Builds

1. Update the Project Version

Open pyproject.toml and increment the minor version number.

2. Build the Project

poetry build

3. Update Dependency in artemis-api/prophet

If the build succeeds, remember to also bump the version number in the pyproject.toml of artemis-api and prophet to match the new version of artemis-model.

Using Alembic for Model Changes

If modifications are necessary for any model:

1. Modify the Model
2. Create an Alembic Revision

alembic revision --autogenerate -m "Description of changes"

3. Upgrade Database Schema

alembic upgrade head

Ensure that the new Alembic script in the versions directory is committed to your git repository. Repeat the build and version update steps as necessary after making changes.
