Language path mixin

This is a technical module to restore the possibility of Odoo to print RML reports in other languages than the user's language (for instance, the customer's language in the case of a sale order).

Odoo 8.0 has lost that capability due to an unlucky combination of technical aspects of the deprecated RML report functionality and the new API. While the static content of the report is translated fine, any translatable fields will still be rendered in the language of the user.

See for the original bug report.

This module provides a tool for developers to work around this bug in their Python code.


With a dependency on this module, you can have any model inherit from the mixin model in your python class definition. You can then assign your class a _language_path member to indicate where to find the language into which its reports are to be translated. See the following code example:

class SaleOrder(models.Model):
    _name = 'sale.order'
    _inherit = ['sale.order', 'language.path.mixin']
    _language_path = 'partner_id.lang'

In RML reports for such a model, you can then iterate over the records in the correct language using

[[ repeatIn(objects.with_language_path(), 'o') ]]

  • Kudos if you find a way to do this more elegantly, preferably with a simple bugfix in the Odoo core
