Generate Barcodes for any Models (Abstract)

This module expends Odoo functionality, allowing user to generate barcode depending on a given barcode rule for any Model.

For exemple, a typical pattern for products is "20.....{NNNDD}" that means that: * the EAN13 code will begin by '20' * followed by 5 digits (named Barcode Base in this module) * and after 5 others digits to define the variable price * a 13 digit control

With this module, it is possible to:

  • Affect a pattern (barcode.rule) to a model
  • Define a Barcode base:
    • manually, if the base of the barcode must be set by a user. (typically an internal code defined in your company)
    • automaticaly by a sequence, if you want to let Odoo to increment a sequence. (typical case of a customer number incrementation)
  • Generate a barcode, based on the defined pattern and the barcode base


This module use an extra python library named 'viivakoodi' you should install to make barcode generation works properly. 'viivakoodi' is a more active for of 'pyBarcode'.

sudo pip install viivakoodi


To configure this module, you need to:

  • Go to Settings / Technical / Sequences & Identifiers / Barcode Nomenclatures
  • Select a Nomenclature
  • Create or select a rule
  • For manual generation, set:
    • 'Base set Manually' in 'Generate Type'
    • Set the model
  • For automatic generation, set:
    • 'Base managed by Sequence' in 'Generate Type'
    • Set the model
    • Generate a new sequence by button, or affect a existing one

In all cases, padding will be computed automaticaly, based on the number of '.' in the Barcode Pattern field.


This module is an abstract module. You can configure Barcode Rule, but to enable this feature, you need to install an extra module for a given model. This repository provide 'barcodes_generator_product' and 'barcodes_generator_partner' module to generate barcode for product or partner model.

Alternatively, you can develop a custom module for a custom model. See 'Inheritance' parts.

If you want to generate barcode for another model, you can create a custom module that inherits on 'barcodes_generator_abstract' and inherit your model like that:

class MyModel(models.Model):
_name = 'my.model' _inherit = ['my.model', 'barcode.generate.mixin']
class barcode_rule(models.Model):

_inherit = 'barcode.rule'

generate_model = fields.Selection(selection_add=[('my.model', 'My Model')])

Finally, you should inherit your model view adding buttons and fields.


Your model should have a field 'barcode' defined.

Known issues / Roadmap

1. On barcode.rule model, constraint and domain system could be set between 'type' and 'generate_model' fields.
