AttributeError: 'mail.template' object has no attribute 'generate_email'

Question

I am using Odoo browser and want to generate email from template and send. I don't want to use the send_mail() method directly. Here is my code.

data = records
template_object = env['mail.template']
template_id = template_object.search([('name', '=', 'Custom_Email_Template')]).id
for record in data:
    template = template_object.browse(template_id)
    email_body = template.generate_email(record.id)
    email_values = {
    'subject': "",
    'body_html': email_body,
    'email_to': '[email protected]'   }

env['mail.mail'].create(email_values).send()

Answer 1

You need to pass the fields parameter

Example

values = template.generate_email(record.id, ['body_html'])

Edit: You can try the following in a demo database:

template = env.ref('sale.mail_template_sale_confirmation')
record = env.ref('sale.sale_order_7')
values = template.generate_email(record.id, ['body_html'])

body_html = values['body_html']
