custom report through python odoo 9

Question

How to pass multiple module data to a QWeb report? Is there something similar to passing dictionary in rendering html from controller?

Answer 1

Below is the code to create a custom Model report which is wrapped on v9 API. Creating custom object report is three step process

1. Create RML Prase Custom Report Object
2. Wrap RML Report to AbstractModel Report for qweb engine.
3. Design template for the custom object.
4. Register your under report registry.

All Four Part listed here with possible sample code.

RML Prase Custom Report Object

import time
from openerp.osv import osv
from openerp.report import report_sxw


class CustomReportPrint(report_sxw.rml_parse):

    def __init__(self, cr, uid, name, context):
        super(CustomReportPrint, self).__init__(cr, uid, name, context=context)
        self.localcontext.update({
            'time': time,
            'lst': self._lst,
            'total': self._some_total,
            'get_records':self._get_records,
        })

    def _get_records(self, res_ids):
        records = self.pool.get('res.partner').browse(self.cr, self.uid, res_ids)
        return records

    def _lst(self, employee_id, dt_from, dt_to, max, *args):
        #Your code goes here
        return res

    def _some_total(self, employee_id, dt_from, dt_to, max, *args):
        #Your code goes here
        return [result_dict]

Wrapping RML Prase Object tot he QWeb Engine.

class report_custom_print(osv.AbstractModel):
    _name = 'report..report_custom_print'
    _inherit = 'report.abstract_report'
    _template = '.report_custom_print'
    _wrapped_report_class = CustomReportPrint

Report XML look as below as you can see I am calling get_records from custom report model.

Registering Report

    
        Custom Print Report
        qweb-pdf
        res.partner
        .report_custom_print
        .report_custom_print
    

In custom Rml report Object you can define as many functions as you like and register them under __int__ and you can call those function directly on yor rpeort and mutpllate data as you need.

PS: replace with your module to make wit works correct.

Hope this will help.
