# macao-pos

## Installation

The only requirements are Python 3 and virtualenv as you're going to install all
the modules through pip.

If you're using MySQL or PostgreSQL create now a new user and database. You can
also use SQLite for testing purposes.

```
cd /var/www
git clone ...
cd macao-pos
virtualenv -p python3 env
source env/bin/activate
pip install -r requirements.txt
```

Now you need to configure this software. Inside `doc/` you'll find some
examples. The default path for configurations in `conf/` but you can also use
`~/.config/pos`, `/usr/local/etc/pos` and `/etc/pos` that will be checked in
this order.

For a testing environment you can just do:
```
mkdir conf
cp docs/config_core/core_debug_sqlite.ini conf/core.ini
cp docs/config_logging/logging_debug.yaml conf/logging.yaml
```

and you're ready to go.

For a production environment:
```
cd /var/www/macao-pos
mkdir conf
cp docs/config_core/core_production_mysql.ini conf/core.ini
cp docs/config_logging/logging_production.yaml conf/logging.yaml
```

and then edit the conf/core.ini file to adjust the database params. Don't forget
to change the SECRET_KEY value (`openssl rand -hex 32` will help you).

If you want to change the log file path open your `conf/logging.yaml` and 
change the `filename` field of the `file` entry inside the `handlers` category.

## Building the database

You also need to add some entries to the database.

First of all add a new user. Get inside the virtualenv and then just do:

```
python3 cli.py user add username password
```

Add some products with:

```
python3 cli.py product add "Birra media" 300
python3 cli.py product add "Birra grande" 400
python3 cli.py product add "Cocktail" 500
python3 cli.py product add "Vino" 400
python3 cli.py product add "Amaro" 200
python3 cli.py product add "Acqua" 100
```

And finally add and event you can play with:
```
python3 cli.py event add "My party" --start "2017-03-19 22:00" --end "2017-03-22 07:00"
```

## Running

You can run this software with from the virtualenv with:

```
python3 web.py
```

If you want to use a read httpd you can setup uwsgi as follows:

```
[uwsgi]
socket = 127.0.0.1:9000

chdir = /var/www/macao-pos
wsgi-file = web.py
virtualenv = env

master
workers = 1
max-requests = 200
harakiri = 30
die-on-term
```
