I'm trying to format a element based on the date specifically I want a link to turn green 7 days before a deadline.

<div class="{{primary1.where( "primary1.dateDiff( &quot;days&quot;, &quot;&quot; )", "<=", 7 ).then( "bg-success", "bg-danger" )}} ">{{primary1}}</div>

Ive tried this but it doesn't work
any ideas??

thanks dennis

Hello Denis,
You cannot use where filter like that. The where filter is only for collections. What you need to do is t add the following filters:
dateDiff (days)
between (lower limit 0; upper limit 7)
then(if valid: bg-success; otherwise: bg-danger)

Thank you very much I will try that
