Firstly you have to check that the attachment you are sending is in pdf format or not, if its not then convert it using get_pdf method.

here is the example of attached report,

@api.multi
def action_rfq_send(self):
    self.ensure_one()
    ir_model_data = self.env['ir.model.data']
    try:
        if self.env.context.get('send_rfq', False):
            temp_id = self.env.ref('purchase.email_template_edi_purchase')
        else:
            temp_id = self.env.ref(
                               'purchase.email_template_edi_purchase_done')
    except ValueError:
        temp_id = False
    try:
        compose_form_id = ir_model_data.get_object_reference('mail',
                         'email_compose_message_wizard_form')[1]
    except ValueError:
        compose_form_id = False

    attach_obj = self.env['ir.attachment']

    pdf_rfq_quote = self.env['report'].sudo().get_pdf([self.id],
                                             'report name')
    result_rfq_quote = base64.b64encode(pdf_rfq_quote)

    attachment_ids = []
    if result:
        attach_data = {
            'name': 'name.pdf',
            'datas': result_rfq_quote,
            'datas_fname': 'name.pdf',
            'res_model': 'ir.ui.view',
            }
        attach_id = attach_obj.create(attach_data)
        attachment_ids.append(attach_id.id)
    if attachment_ids:
        temp_id.write({'attachment_ids': [(6, 0, attachment_ids)]})

    ctx = dict(self.env.context or {})
        ctx.update({
            'default_model': 'purchase.order',
            'default_res_id': self.ids[0],
            'default_use_template': bool(temp_id.id),
            'default_template_id': temp_id.id,
            'default_composition_mode': 'comment',
        })
        return {
            'name': _('Compose Email'),
            'type': 'ir.actions.act_window',
            'view_type': 'form',
            'view_mode': 'form',
            'res_model': 'mail.compose.message',
            'views': [(compose_form_id, 'form')],
            'view_id': compose_form_id,
            'target': 'new',
            'context': ctx,
        }
       

Thank You

it works with pdf file ?

Thanks but that's not my question. I don't want to attach a PDF report, the default invoice's e-mail template already does that. I want to add *another* file in the e-mail

I already solved it by extending the Composer wizard to retrieve the added files in context, but thanks anyway.

I want to do the same, how to solve this?

Thank you.

Hello, this is my implementation using odoo email wizard:

def send_mail(self):
self.ensure_one()
template = self.env.ref('my_module.email_template_payroll', False)
compose_form = self.env.ref('mail.email_compose_message_wizard_form', False)

# attach xml from binary field
if self.xml_data:
xml_name = '%s.xml' % self.name
attachment_ids = []
encoded_data = base64.b64encode(self.xml_data)
decoded_data = base64.b64decode(encoded_data)

if decoded_data:
attach_data = {
'name': xml_name,
'res_name': xml_name,
'datas': decoded_data,
'res_model': 'hr.payslip',
'res_id': self.id,
}
attach_id = self.env['ir.attachment'].create(attach_data)
attachment_ids.append(attach_id.id)

if attachment_ids:
template.write({'attachment_ids': [(6, 0, attachment_ids)]})

ctx = dict()
ctx.update({
'default_model': 'hr.payslip',
'default_res_id': self.id,
'default_use_template': bool(template),
'default_template_id': template.id,
'default_composition_mode': 'comment',
})

return {
'name': _('Compose Email'),
'type': 'ir.actions.act_window',
'view_type': 'form',
'view_mode': 'form',
'res_model': 'mail.compose.message',
'views': [(compose_form.id, 'form')],
'view_id': compose_form.id,
'target': 'new',
'context': ctx,
}

Be careful with the indentation of the code, it got lost when paste text.

Hope it helps
