Using a scheduled task, I need to send an email which will inform on the status of open tasks. After getting the recordset correponding to my search, I found how to load the template and send the email:

mail_template = self.env.ref('test_email.email_template')
mail_template.send_mail(self.id)

But I only got access to the current record in $object. I would like to be able to pass the recordset to the template and loop over it.
