Inventicode 1.0.2

Create labels with QR and barcodes.

Inventicode
===========

Web app for registering objects (an object is just a name associated to a comment and a serial number) and printing sheets of labels with EAN13 barcodes or QR codes. You can also associate a state and a category to these objects.

You define models of paper (size, number, size and background image of labels) and template for labels.

Use cases
---------

* printing customized labels with QR or bar codes,
* changing the state or the category of a set of objects by only scanning their barcode, one-by-one,
* identify a given object by scanning its barcode in the search bar,
* displaying the object page by scanning its QR code.

Installation
------------

sudo apt-get install python3.5 python3.5-dev build-essential
pip install inventicode
CONFIG_FILENAME=`inventicode-django config ini -v 2 | head -n 1 | grep ".ini" | cut -d '"' -f 2`
# create required folders
mkdir -p `dirname $FILENAME` $HOME/inventicode
# prepare a limited configuration file
cat << EOF > $FILENAME
[global]
data = $HOME/inventicode
EOF
# create the database (SQLite by default)
inventicode-django migrate
# prepare static files (CSS, JS, …)
inventicode-django collectstatic --noinput
# create an admin user
inventicode-django createsuperuser
inventicode-aiohttp

You can define new templates for each label, and the default one is:

{% load inventicode %}<h2>{{ code.name }}</h2>
<img class="name qr_code" style="" alt="{{ code.name }}" src="{{ code.name|qr_code|base64_url }}" />
<img class="short_identifier bar_code" style="width: 4cm;" alt="{{ code.short_identifier }}" src="{{ code.short_identifier|bar_code:'ean13'|base64_url }}" />
<h3>{{ code.long_identifier }}</h3>

Available values are:

* code.name
* code.comment
* code.serial
* code.long_identifier (URL to the model)
* code.short_identifier (unique code, usable as EAN13 barcode)

If you load `inventicode`, you can use some filters:

* `qr_code`: QR code as SVG (string)
* `bar_code`: bar code as SVG (string). Available barcodes are 'code39', 'ean', 'ean13', 'ean8', 'gs1', 'gtin', 'isbn', 'isbn10', 'isbn13', 'issn', 'jan', 'pzn', 'upc', 'upca'.
* `base64_url`: transform a string as an embedded base64 url.

You can also define a CSS for the whole page, and the default one is:

.qr_code {
width: 1cm;
height: 1cm;
}
h2 {
width: 100%;
text-align: center;
}
h3 {
text-align: center;
top: 1cm;
position: relative;
text-transform: uppercase;
}
img.bar_code {
width: 3cm;
top: 1cm;
left: -2cm;
}
