I want to add class only when $_first evaluated to true
Example:
<div t-attf-class="carousel-item {{ $_first }}">
To be:
Incase True: <div t-attf-class="carousel-item active">
Incase of false: <div t-attf-class="carousel-item">

Try this one
<t t-foreach="records" t-as="rec">
<div t-attf-class="carousel-item #{ rec_first and 'active' or '' }">
</div>
</t>
it is not $_first you should replace $ with the value of t-as
Thanks Parth, It's works.
Could you Please explain what the meaning of (and 'active' or ' ') and how odoo evaluate it
