Extended Barcodes

In general, the default types of barcodes that Odoo is able to generate is all you may need for most of your business processes.

But sometimes, may raise situations when those barcodes are very limited or don’t behave as well as expected. For example, you may need to print very small barcodes inside a very constraint space in one of your documents, but the resulting Odoo’s barcode doesn’t look good, it can be too blurry to be read by a barcode scanner, while, for example using a different type of barcode (maybe a DataMatrix) can work much better than a traditional linear barcode.

This module extends the available types of barcode images that Odoo is able to produce. By default, from the Odoo documentation the accepted options were:

• Codabar
• Code11
• Code128
• EAN13
• EAN8
• Extended39
• Extended93
• FIM
• I2of5
• MSI
• POSTNET
• QR
• Standard39
• Standard93
• UPCA
• USPS_4State

After installing this module. The default types will be extended with all these new kind of barcode types:

Installation

To install this module, you first need to make sure the package pyzint is available to your Odoo instance:

1. Normally, all you need to do is pip install pyzint inside the Python environment that’s used by your Odoo server.

Usage

To use this module, it’s recommended to follow the approach below:

• First, make a list of all the current barcodes you plan to replace by new kinds of barcodes included in this module. Then note, inside which existing Odoo modules they are currently.

• Then, create a new Odoo module. In the __manifest__.py set it as 'auto_install': True

• Also in the __manifest__.py, edit the 'depends': [] key and add odoo_extended_barcodes followed by all your installed modules where you previously has noticed there are barcodes you want to modify.

• Finally, all you need to do, is inherit the templates where your target barcodes are used, by using the odoo's xpath mechanism, and modify what's needed. Normally all you may need to change is the t-att-src of the <img> tags that frequently are used to locate the barcode that's going to be rendered inside a given template.

  For example, if you have something like this in a your_template <template> record:

  <t t-if="o.product_id.whatever">

  <div class="position-absolute" style="bottom: 0px;">

  <img class="h-100" t-att-src="'/report/barcode/?type=%s&amp;value=%s&amp;width=%s&amp;height=%s' % ('Code128', o.product_id.default_code, 9000, 1100)" alt="Barcode"/>

  </div>

  </t>

  all you need to do is:

  <template id="your_template" inherit_id="module.your_template">

  <xpath expr="//img" position="attributes">

  <attribute name="t-att-src">'/report/barcode/?type=%s&amp;value=%s&amp;scale=%s&amp;height=%s' % ('DATAMATRIX', o.product_id.default_code, 5, 1100)</attribute>

  </xpath>

  </template>

Then, instead a traditional Code128 barcode, you will end up with something as beautiful as this:
