Usage

Actions must be configured with the following data in the context: * model: Model where we can find the method (required) * method: Method to execute (required) * res_id: Id as base (optional)

The method must return an action. Installing this module with demo data will install a demo application that allows the system administrator to find a partner by the external reference encoded in a barcode.

Go to Settings / Find partners and scan a barcode that contains the internal reference of an existing partner. As soon as you read the barcode the system will redirect you to that partner’s form view.

Technical implementation of this example:

Action:

<act_window id="res_partner_find"
    name="Find Partner"
    res_model="barcode.action"
    view_mode="form"
    view_type="form"
    context="{'default_model': 'res.partner', 'default_method': 'find_res_partner_by_ref_using_barcode'}"
    target="new"/>
<menuitem id="menu_orders_customers" name="Find partners"
    action="res_partner_find"
    parent="base.menu_administration"/>

Python code:

import json
from odoo import api, models, _
from odoo.tools.safe_eval import safe_eval
class ResPartner(models.Model):
    _inherit = 'res.partner'
    @api.multi
    def find_res_partner_by_ref_using_barcode(self, barcode):
        partner = self.search([('ref', '=', barcode)], limit=1)
        if not partner:
            action = self.env.ref('res_partner_find')
            result = action.read()[0]
            context = safe_eval(result['context'])
            context.update({
                'default_state': 'warning',
                'default_status': _('Partner with Internal Reference '
                                    '%s cannot be found') % barcode
            })
            result['context'] = json.dumps(context)
            return result
        action = self.env.ref('base.action_partner_form')
        result = action.read()[0]
        res = self.env.ref('base.view_partner_form', False)
        result['views'] = [(res and res.id or False, 'form')]
        result['res_id'] = partner.id
        return result
