I want to render a mail.template, but getting this following error:
Error:
Odoo Server Error

AttributeError: 'mail.template' object has no attribute 'render_template'
In this is my models.py
from odoo import api, fields, models, _import time
from odoo.exceptions import UserError
import logging
_logger = logging.getLogger(__name__)
class invoice(models.Model):
_name = 'account.invoice'
_inherit = 'account.invoice'
printer_data = fields.Text(string="Printer Data", required=False, )
@api.multi
def generate_printer_data(self):
tpl = self.env['mail.template'].search([('name', '=', 'Dot Matrix Invoice')]).
data = tpl.render_template(tpl.body_html, 'account.invoice', self.id, post_process=False)
self.printer_data = data
@api.multi
def action_invoice_cancel(self):
self.printer_data = ''
return super(invoice, self).action_cancel()
@api.multi
def action_invoice_open(self):
res = super(invoice, self).action_invoice_open()
self.generate_printer_data()
return res
So, what's wrong with that code ?, any help would be very appreciated :)
