Introduction
============
*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
:py:class:`accounting.utils.user.UserUtilityInterface` to the
:py:func:`accounting.init_app` function. ``UserUtilityInterface``
contains everything *Mia! Accounting* needs.
See an example in :ref:`example-userutils`.
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.
