Hi All,
I'm trying to generate qr code for employee name in my custom module but Iam unable to write the barcode url..and would like to share the code which i have written in my custom module.
class Employee_table(models.Model):
_inherit = 'hr.employee'
def get_image(self, value, width, hight, hr, code='QR'):
""" genrating image for barcode """
options = {}
if width:options['width'] = 150
if hight:options['hight'] = 150
if hr:options['humanReadable'] = True
try:
ret_val = createBarcodeDrawing(code, value=str(value), **options)
except Exception, e:
raise ValueError(e)
return base64.encodestring(ret_val.asString('jpg'))
@api.multi
def _compute_barcode_urll(self):
dom_name = self.env['base.config.settings'].search([], limit=1)
for record in self:
if record.name_related:
if dom_name.alias_domain:
domain_nm = dom_name.alias_domain
else:
domain_nm = 'localhost:8069'
record.barcode_urll = "%s/hr/%s?" % (domain_nm, slug(record.name_related))
image = self.get_image(record.barcode_urll,
code='QR',
width=150, hight=150,
hr=True)
record.write({'qr_image1': image})
barcode_urll = fields.Char(compute='_compute_barcode_urll', string='Related URL')
qr_image1 = fields.Binary('Barcode Image')
but iam getting following error.
Odoo Server Error
