Hi everyone!

I would like to attach PDF (or whatever file type...) to the quotation sent by email..

For this, i'm trying to override the send_mail method from mail_compose_message class. I succeeded to create a new mail with hardcoded values and to attach my files to that email, but of course i would like to attach the files to the email created with the pop up view when "send by mail" is clicked.

How can i override that method? I think i should call super.send_mail() but i don't know how to add my attachment if i do that :/

Here is my code with hardcoded values:

class mail_compose_message(osv.Model):
    _inherit = 'mail.compose.message'

    @api.multi
    def send_mail(self):
        #retrieve order
        order_id =self.env.context["active_id"]
        order = self.env['sale.order'].browse([order_id])
        attachment_ids = []
        #create a new ir.attachment
        ir_attachment = self.env['ir.attachment']
        mail = self.env["mail.mail"].create({"email_from":"a@a.com","email_to":"b@b.com","subject":"subject","body_html":"d"})

        #for each line, look for product fiches. Add fiches to attachment
        for line in order.order_line:
            for product_fiche in line.product_id.documents: 
                attachment_data = {'name': product_fiche.name,
                                   'datas_fname': product_fiche.datas_fname,
                                   'datas': product_fiche.datas,
                                   'res_model': "mail.mail",
                                   'res_id': mail.id,
                                   }
 
                attachment_ids.append(ir_attachment.create(attachment_data).id)

        mail.write({'attachment_ids': [(6, 0, attachment_ids)]})
        return mail.send()

I suppose i shouldn't be creating the email myself, and only send the attachment_ids to the super method, but i don't know how to do that. Could someone help me?
