I have a kept a binary field for attachment file. If I click on the confirm button, mail should be send along with attachment file.

I have tried this code,

class Test(models.Model)

_name = 'test'

soft_copy = fields.Binary(string="Soft Copy")

file_name = fields.Char(string="File Name") 

def action_confirm(self):

  self.ensure_one()

  self.state = 'confirm'

  email_template = self.env.ref('module1.test_email_template')

  email_template.send_mail(self.id, raise_exception=False, force_send=True)

Email Template,

<record id="test_email_template" model="mail.template">

            <field name="name">Test</field>

            <field name="subject">Checking Test</field>

            <field name="email_from">xyz@gmail.com</field>

            <field name="email_to">$employee_id.work_mail}</field>

            <field name="model_id" ref="module1.model_test"/>

            <field name="report_template" ref="module1.test_reports"/>

            <field name="report_name">Test</field>

            <field name="auto_delete" eval="True"/>

            <field name="body_html"><![CDATA[ -----Content---

            ]]></field>
