Hello,

I'm developing a module to extend Invoice (Odoo 11). I have added a binary field into the Invoice model, and I want to be able to send this binary via mail.

Sending an e-mail directly and attaching a binary is simple, but I want to open the composer wizard with the binary as an attachment. Currently, the "Send by e-mail" button opens the composer with Odoo's default PDF report; I want to add another file in that view.

This is my current code to try to attach the files. This piece of code itself runs and doesn't generate any errors, but the composer wizard just ignores the added info.

@api.multi
def action_invoice_sent(self):
    self.ensure_one()

    result = super(AccountInvoice,self).action_invoice_sent()

    pdf_attachment_id = self.env['ir.attachment'].create({
        'name': ("%s" %self.pdf),
        'datas': self.pdfname,
        'datas_fname': self.pdf,
        'res_model': 'mail.compose.message',
        'res_id': 0,
        'type': 'binary'
    })

    result['context'].update({
        'attachment_ids': [(6,0,[pdf_attachment_id.id])]
    })

    return result

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

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
