Hi All,

I am using Odoo15, in which I have a requirement to change the email subject of a custom template based on a condition. The template is designed in code the itself.

My email subject is as follows: This is a test mail for {{ object.my_field_name }}

For condition check, 

if condition_satisfies: subject = "Condition Satisfied - " + subject

else: subject = subject.

In case of condition satisfied, while I am triggering the mail, the subject is coming as 

Condition Satisfied - This is a test mail for {{ object.my_field_name }} 

instead of actual value of my_field_name.

Do anyone have a solution to resolve this?
