How to override correctly point_of_sale.report_salelines?

Hello guy,

Trying to override the original point_of_sale.report_saleslines' to include a new docargs paperformat in my qweb report. 

The paperformat works in my qweb report.

But impossible to process lines like         <t t-esc="total_quantity(o)"/>   in my qweb report (because of o).

I'm pretty sure that I have a trouble with wrapped_report_class. But I don't understand how to manage it.

Here is my override :

class report_saleslines_pt(osv.AbstractModel):
    _name = 'report.point_of_sale.report_saleslines'
    _template = 'point_of_sale.report_saleslines'
    _inherit = 'report.abstract_report'
    _wrapped_report_class = None

    def render_html(self, cr, uid, ids, data=None, context=None):

        context = dict(context or {})

        paperformat_obj = context.get('chosenPaper')  #works well
        
        # If the key 'landscape' is present in data['form'], passing it into the context
        if data and data.get('form', {}).get('landscape'):
            context['landscape'] = True
        

        if context and context.get('active_ids'):

            # Browse the selected objects via their reference in context
            model = context.get('active_model') or context.get('model')
            objects_model = self.pool[model]
            objects = objects_model.browse(cr, uid, context['active_ids'], context=context)
        else:

            # If no context is set (for instance, during test execution), build one

            model = self.pool['report']._get_report_from_name(cr, uid, self._template).model

            objects_model = self.pool[model]
            objects = objects_model.browse(cr, uid, ids, context=context)
            context['active_model'] = model
            context['active_ids'] = ids
            
        # Generate the old style report
        
        wrapped_report = self._wrapped_report_class(cr, uid, '',  context=context)
        _logger.error('LAPAGEPT_CLASSES :: RENDER_HTML() %s %s', 'WRAPPED_REPORT :: ', wrapped_report)
        wrapped_report.set_context(objects, data, context['active_ids'])

        # Rendering self._template with the wrapped report instance localcontext as

        # rendering environment
        docargs = wrapped_report.localcontext
        docargs['docs'] = docargs.get('objects')

        # Used in template translation (see translate_doc method from report model)
        docargs['doc_ids'] = context['active_ids']
        docargs['doc_model'] = model
        docargs['paperformat'] = paperformat_obj

        return self.pool['report'].render(cr, uid, [], self._template, docargs, context=context)
    
report_saleslines_pt()

Here is the error. 

Traceback (most recent call last): File "/home/odoo-test/addons/report/controllers/main.py", line 122, in report_download response = self.report_routes(reportname, docids=docids, converter='pdf') File "/home/odoo-test/openerp/http.py", line 395, in response_wrap response = f(*args, **kw) File "/home/odoo-test/addons/report/controllers/main.py", line 65, in report_routes pdf = report_obj.get_pdf(cr, uid, docids, reportname, data=options_data, context=context) File "/home/odoo-test/openerp/api.py", line 241, in wrapper return old_api(self, *args, **kwargs) File "/home/odoo-test/addons/report_lapagept/models/report_lapagept.py", line 134, in get_pdf html = self.get_html(cr, uid, ids, report_name, data=data, context=context) File "/home/odoo-test/openerp/api.py", line 241, in wrapper return old_api(self, *args, **kwargs) File "/home/odoo-test/addons/report_lapagept/models/report_lapagept.py", line 112, in get_html return particularreport_obj.render_html(cr, uid, ids, data=data, context=context) File "/home/odoo-test/openerp/api.py", line 241, in wrapper return old_api(self, *args, **kwargs) File "/home/odoo-test/addons/report_lapagept/lapagept_classes.py", line 80, in render_html wrapped_report = self._wrapped_report_class(cr, uid, '', context=context) TypeError: 'NoneType' object is not callable

should I also create a new parser class?

And if I would want to use the same wrapped_report_class than the original AbstractReport class (i.e. openerp.addons.point_of_sale.report.pos_lines.pos_lines)?

It was not the good way to proceed.

Here is what we finally needed : An override of 'report.point_of_sale.report_saleslines'.

class pos_lines_pt(report_sxw.rml_parse):

    def __init__(self, cr, uid, name, context):
        super(pos_lines_pt, self).__init__(cr, uid, name, context=context)
        self.total = 0.0
        paperformat_obj = context.get('chosenPaper') #chosenPaper is defined by us somewhere else.

        self.localcontext.update({
            'time': time,
            'total_quantity': self.__total_quantity__,
            'taxes':self.__taxes__,
            'paperformat': paperformat_obj

        })
   

    def __total_quantity__(self, obj):
        tot = 0
        for line in obj.lines:
            tot += line.qty
        self.total = tot
        return self.total

    def __taxes__(self, obj):
        self.cr.execute ( " Select acct.name from pos_order as po " \
                              " LEFT JOIN pos_order_line as pol ON po.id = pol.order_id " \
                              " LEFT JOIN product_taxes_rel as ptr ON pol.product_id = ptr.prod_id " \
                              " LEFT JOIN account_tax as acct ON acct.id = ptr.tax_id " \
                              " WHERE pol.id = %s", (obj.id,))
        res=self.cr.fetchone()[0]
        return res


class report_pos_lines_pt(osv.AbstractModel):
    _name = 'report.point_of_sale.report_saleslines'
    _inherit = 'report.abstract_report'
    _template = 'point_of_sale.report_saleslines'
    _wrapped_report_class = pos_lines_pt
