How to send email from odoo module using email template

Hi,

The first thing that you need to do is add a dependency to other modules that you’ll need,

'depends': ['mail'],

The next step is to create a new XML record like given are below,

 <record id="email_template" model="mail.template">
    <field name="name">EMAIL TEMPLATE</field>
    <field name="model_id" ref="emai_template.model_example.mail"/>
    <field name="auto_delete" eval="True"/>
    <field name="email_from">${(object.res_user_id.email}</field>
    <field name="email_to">${object.client_name.email}</field>
     <field name="report_template" ref="action_example_pdf"/>
    <field name="subject">${object.amc}</field>
    <field name="body_html"><![CDATA[
 <p>Dear ${(object.client_name.name)},<br/><br/>
 Good job, you've just created your first e-mail template!<br/></p>
      Regards,<br/>
      ${(object.company_id.name)} ]]></field>
</record>

Odoo e-mail templates come with jinja2 by default. This means that you can access any value on a record and fill it in on the e-mail automatically,

eg:-

<field name="subject">${object.amc}</field>

The next thing is we want to create python function like given below.

@api.multi
def action_send_amc(self):
    self.ensure_one()
    ir_model_data = self.env['ir.model.data']
    try:
        template_id = ir_model_data.get_object_reference('module_name', 'template_name')[1]
    except ValueError:
        template_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
    ctx = {
        'default_model': 'exmaple.email',
        'default_res_id': self.ids[0],
        'default_use_template': bool(template_id),
        'default_template_id': template_id,
        'default_composition_mode': 'comment',
        'mark_so_as_sent': True,
        'force_email': True
    }
    return {
        '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,
    }

Thanks
