How to send mail for multiple users(CC) through code? - email

Question

This is the code I am trying currently for one person
def send_mail_employee(self,cr,uid,ids,context=None):
record_obj = self.browse(cr,uid,ids,context=context)
ir_model_data = self.pool.get('ir.model.data')
template_obj = self.pool.get('email.template')
attch_ids = []
for rec in record_obj:
if not rec.name.work_email:
raise osv.except_osv(_('Warning!'), _('Please configure employee email address!'))
else:
for attch in rec.attchment_lines:
attch_ids.append(attch.id)
template_id = ir_model_data.get_object_reference(cr,uid,'registers', 'email_template_register_courier')[1]
self.pool.get('email.template').write(cr,uid,template_id,{'body_html' : rec.email_body,'subject' : rec.subject,'attachment_ids':[(6,0,attch_ids)]})
self.pool.get('email.template').send_mail(cr,uid,template_id,rec.id,force_send=True,context=context)
raise osv.except_osv(_('Success'), _('Mail has been sent successfully'))
return True
and the template is like this
<openerp>
<data>
<!--Email template for Register Courier-->
<record id="email_template_register_courier" model="email.template">
<field name="name">Notification for Courier</field>
<field name="email_from">${object.name.work_email}</field>
<field name="subject">Notification for Courier</field>
<field name="email_to">${object.name.work_email}</field>
<field name="email_cc">${object.cc.work_email}</field>
<field name="model_id" ref="model_registers_courierin"/>
<field name="auto_delete" eval="True"/>
<field name="body_html"><![CDATA[<div style="font-family: 'Lucica Grande', Ubuntu, Arial, Verdana, sans-serif; font-size: 12px; color: rgb(34, 34, 34); background-color: #FFF; ">
<p>Hello ${object.name.name},</p>
<p>This email is to inform you that your courier received</p>
<P>Thank you</p>
</div>
]]>
</field>
</record>
</data>
</openerp>
Now i have created a one2many field like a tree view named as 'ref_cc', i want to send the whole record to those list of persons in the email cc by code.Any idea would be really helpful.
