Hi,

I have the following report defined:

 <report
            id="report_invoice_custom"
            model="account.invoice"
            string="Custom invoice report"
            report_type="qweb-pdf"
            name="custom_reports.invoice_custom"
            attachment_use="False"
            file="custom_reports.invoice_custom"
                attachment = "(object.state in ('open','paid')) and ('F_'+(object.number or '').replace('/','')+'.pdf')"
        />

And I am defining a new parser for it:

from openerp.report import report_sxw
from openerp.osv import osv
from openerp import api

class invoice_parser(report_sxw.rml_parse):

    def __init__(self, cr, uid, name, context):
        super(invoice_parser, self).__init__(cr, uid, name, context=context)
        self.localcontext.update({
            'select_value': self._selection_value,
        })

    def _selection_value(self, value):
        if value:
            tax_pool = self.pool.get('account.tax')
            tax_ids = tax_pool.search(self.cr, self.uid, [('name', '=', value)])
            if tax_ids:
                tax_id = tax_pool.browse(self.cr, self.uid, tax_ids[0])
                return self._translate(tax_id.description)
        return value

class report_custom_invoice_parser(osv.AbstractModel):
    _name = 'report.module.invoice.wrapper'
    _inherit = 'report.abstract_report'
    _template = 'custom_reports.invoice_custom'
    _wrapped_report_class = invoice_parser

If I understood how parsers work, I guess I have to add something similar to the following code to register the parser:

report_sxw.report_sxw(
        'custom_reports.invoice_custom',
        'account.invoice',
        'custom/custom_reports/xml/custom_reports.xml',
        parser= select_value )

Could someone help me to understand how to register the parser?

Thanks,
