Mia! Accounting
===============


Description
===========

*Mia! Accounting* is an accounting module for Flask_ applications.
It is designed both for mobile and desktop environments.  It
implements `double-entry bookkeeping`_.  It generates the following
accounting reports:

* Trial balance
* Income statement
* Balance sheet

In addition, *Mia! Accounting* tracks offsets for unpaid payables and
receivables.


Live Demonstration and Test Site
================================

There is a `live demonstration`_ for *Mia! Accounting*.  It runs the
same code as the `test site`_ in the `source distribution`_.  It is
the simplest website that works with *Mia! Accounting*.  It is also
used in the automatic tests.

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


Installation
============

Install *Mia! Accounting* with ``pip``:

::

    pip install mia-accounting

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


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


Navigation Menu
===============

Include the navigation menu in the `Bootstrap navigation bar`_ in your
base template:

::

    <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.
