I want to print barcode with Label module, on OpenERP 6.1

I go to "settings -> customization -> Labels -> Label templates" and I edit one of the templates. To print barcode I tried:

  • first, a harcoded code

    <barcode x="1cm" y="1cm" height="1cm" code="EAN13">7501031311309</barcode>

  • second, I tried with ${object.ean13}:

    <barcode x="1cm" y="1cm" height="1cm" code="EAN13">${object.ean13}</barcode>

  • finally on 3 lines:

    <barcode x="1cm" y="1cm" height="1cm" code="EAN13">

    ${object.ean13}

    </barcode>

the first works, but always the same barcode, obviously.

the second I get:

Illegal assignment of '${object.ean' to 'value' in class Ean13BarcodeWidget

(<type 'exceptions.AttributeError'>, AttributeError("Illegal assignment of '${object.ean' to 'value' in class Ean13BarcodeWidget",), <traceback object at 0xe0c9784>)

and the third:

Illegal assignment of '<para style=' to 'value' in class Ean13BarcodeWidget

(<type 'exceptions.AttributeError'>, AttributeError("Illegal assignment of '<para style=' to 'value' in class Ean13BarcodeWidget",), <traceback object at 0xccb9554>)

How I should configure the barcode tag to get ean13 from each product?

had to change label module:

diff --git a/openerp/addons_extra/label/label_report_engine.py b/openerp/addons_extra/label/label_report_engine.py
index b1419d6..edce844 100644

                     tline = re.sub(r'(<[^>]*>)', '', line) # To exclude <...> tags
                     tline = re.sub(r'(\$\{([\w\.]+)\s*[^}]*\})', r'<\2>\1</\2>', tline)
                 else: # Line that only includes report tags like <tr>, <td>, <blockTable>, <nextFrame/>, ... to control the report format

and use barCode like in the 3rd example

<barcode x="1cm" y="1cm" height="1cm" code="EAN13">
${object.ean13}
</barcode>

do not insert spaces at the beginning of lines
