Sending email using scheduled action - odoo-8

Question

I'm working on an odoo project and I need to send emails automatically every day at 10 am. I have created the scheduled action but I've got a problem. This is the method I use to perform sending action
#api.model
def send_mails(self):
domain = [['name', 'like', 'Production Report']]
template = self.env['email.template'].search(domain)[0]
template.send_mail(self.id, True)
After the execution of the method it gives this traceback
2016-11-03 17:35:15,158 4912 ERROR sintramdb openerp.addons.base.ir.ir_cron: Call of self.pool.get('production.ouvrages').send_mails(cr, uid, *()) failed in Job 9
Traceback (most recent call last):

AttributeError: 'bool' object has no attribute 'lang'
If i replace the #api.model by #api.one or #api.multi i get the following error
TypeError: old_api() takes at least 4 arguments (3 given)
Note: With #api.one or #api.multi annotation it wokrs perfectly if i use a button click to call the method.

Answer 1

First of all thanks guys for your quick replies!!
After i tried your fixes i wasn't still able to solve the problem. So i decided to look deeply into the email_template.py file in email_template addon and after being stuck with some errors i finally got something working. Bellow is my solution (with the old api style of course)
def send_mails(self, cr, uid, *args, **kwargs):
domain = [['name', 'like', 'Production Report']]
template_id = self.pool.get('email.template').search(cr, uid,domain,offset=0, limit=None, order=None, context=None, count=False)[0]
template_obj = self.pool.get('email.template').browse(cr, uid, template_id)
template_obj.send_mail(3, True, None)
I hope it will help someone else

Try this
#api.v8
#api.model
def send_mails(self):
domain = [['name', 'like', 'Production Report']]
template = self.env['email.template'].search(domain)[0]
template.send_mail(self.id, True)
if that doesn't work try this solution.
#api.model
def send_mails(self):
domain = [['name', 'like', 'Production Report']]
template = self.env['email.template'].search(domain)[0]
template.send_mail(self._cr,self._uid,self.id, True)
