 # mia-accounting
 The Django Accounting application.
 ## Description
 `mia-accounting` is a Django accounting application.  It was a re-write of my
 own private accounting application written in Perl for `mod_perl` in 2007.  The
 revision aims to be mobile-friendly with Bootstrap, with a modern back-end
 framework and front-end technology like jQuery.  The first revision was in
 Perl / Mojolicious in 2019.  This is the second revision in Python / Django
 in 2020.
 `mia-accounting` comes with two parts:
 * The `accounting` application contains the main accounting application. 
 * The `mia_core` application contains core shared libraries that are used by the
 accounting application and my other applications.
 You may try it in live demonstration at
 https://accounting.imacat.idv.tw/accounting .
 * Username: `admin`
 * Password: `12345`
 ## Installation
 ### Install
 `mia-accounting` requires Python 3.6 or above to work.
 Install `mia-accounting` with `pip`.
 ```
 pip install mia-accounting

 ```
 INSTALLED_APPS = [
  'mia_core.apps.MiaCoreConfig',

 Make sure the locale middleware is in the `MIDDLEWARE` section of your
 `settings.py`, and add it if it is not added yet.
 ```
 MIDDLEWARE = [
  ...
  'django.middleware.locale.LocaleMiddleware',
  ...

 ```
 ### `urls.py`
 Add the `accounting` application in the `urlpatterns` of your `urls.py`.
 ```
 urlpatterns = [
  ...
  path('accounting/', decorator_include(login_required, 'accounting.urls')),
  ...

 ```
 Make sure `i18n` and `jsi18n` are also in the `urlpatterns` of your `urls.py`,
 and add them if they are not added yet.
 ```
 urlpatterns = [
  ...
  path('i18n/', include("django.conf.urls.i18n")),
  path('jsi18n/', JavaScriptCatalog.as_view(), name='javascript-catalog'),
  ...
 ]
 ```
 ### `base.html`
 Add the following to the very beginning of your base template
 `base.html`, before your first real HTML tag.
 ```

 {% block settings %}{% endblock %}
 ```
 Add the CSS and JavaScripts in the `<head>...</head>` section of your
 base template `base.html`.

 ======================================
 The Mia! Accounting Django Application
 ======================================
 Obsolete Project
 ================
 This project is obsolete.  No further Django release will be
 available.  Check the current `Mia! Accounting project`_ for Flask_,
 and the current `Mia! Accounting live demonstration`_.
 .. _Mia! Accounting project: https://github.com/imacat/mia-accounting
 .. _Flask: https://flask.palletsprojects.com
 .. _Mia! Accounting live demonstration: https://accounting.imacat.idv.tw
 Warning
 =======
 This is the last release of Django.  It will be replaced by a new
 Flask_ release, starting from scratch.  Do not upgrade to the next
 release, as it will not work.
 This was my first large Python project, and at that time, I had zero
 experience with Django.  I ended up in a mess with Django MVT.  The
 code is unnecessarily complicated, and I do not actually know how the
 views work anymore.
 If you are new to the Mia! Accounting project, please skip this and
 try the new release.  You may contact me if you have problems with
 the existing installation, but I may not be able to help you.
 Description
 ===========
 *mia-accounting* is a Django_ accounting application.  It was
 rewritten from my own private accounting application in Perl/mod_perl_
 in 2007.  The revision aims to be mobile-friendly with Bootstrap, with
 a modern back-end framework and front-end technology like jQuery.  The
 first revision was in Perl/Mojolicious_ in 2019.  This is the second
 revision in Python/Django in 2020.
 The Mia! Accounting Django application comes with two parts:
 - The ``accounting`` application contains the main accounting
  application.
 - The ``mia_core`` application contains core shared libraries that are
  used by the ``accounting`` application and my other applications.
 You may try it in live demonstration at:
 - URL: https://accounting-django.imacat.idv.tw/accounting
 - Username: ``admin``
 - Password: ``12345``
 .. _Django: https://www.djangoproject.com
 .. _mod_perl: https://perl.apache.org
