You may also download the from the PyPI project page or the release page on the Git repository.

Test Site and Live Demonstration

You may find a working example in the test site in the source distribution. It is the simplest website that works with Mia! Accounting. It is used in the automatic tests. It is the same code run for live demonstration.

If you do not have a running Flask application or do not know how to start one, you may start with the test site.

Prerequisites

You need a running Flask application with database user login. The primary key of the user data model must be integer. You also need at least one user.

The following front-end JavaScript libraries must be loaded. You may download it locally or use CDN.

Bootstrap 5.2.3 or above
FontAwesome 6.2.1 or above
Decimal.js 6.4.3 or above
Tempus-Dominus 6.4.3 or above

Configuration

You need to pass the Flask app and an implementation of UserUtilityInterface to the init_app function. UserUtilityInterface contains everything Mia! Accounting needs.

The following is an example configuration for Mia! Accounting.

from flask import Response, redirect
from .auth import current_user()
from .modules import User

def create_app(test_config=None) -> Flask:
    app: Flask = Flask(__name__)

    ... (Configuration of SQLAlchemy, CSRF, Babel_JS, ... etc) ...

    import accounting

    class UserUtils(accounting.UserUtilityInterface[User]):

        def can_view(self) -> bool:
            return True

        def can_edit(self) -> bool:
            return "editor" in current_user().roles

        def can_admin(self) -> bool:
            return current_user().is_admin

        def unauthorized(self) -> Response:
            return redirect("/login")

        @property
        def cls(self) -> t.Type[User]:
            return User

        @property
        def pk_column(self) -> Column:
            return User.id

        @property
        def current_user(self) -> User | None:
            return current_user()

        def get_by_username(self, username: str) -> User | None:
            return User.query.filter(User.username == username).first()

        def get_pk(self, user: User) -> int:
            return user.id

    accounting.init_app(app, UserUtils())

    ... (Any other configuration) ...

    return app

Database Initialization

After the configuration, run the accounting-init-db console command to initialize the accounting database. You need to specify the username of a user as the data creator.

% flask --app myapp accounting-init-db -u username

<nav class="navbar navbar-expand-lg bg-body-tertiary bg-dark navbar-dark">
  <div class="container-fluid">
    ...
    <div id="collapsible-navbar" class="collapse navbar-collapse">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        ...
        {% include "accounting/include/nav.html" %}
        ...
      </ul>
      ...
    </div>
  </div>
</nav>

Check your Flask application and see how it works.
