templating: t-if for string length

I want to display an origin ('City A') and destination ('City B') in a kanban template. These are both char fields in my model. I want to bit an arrow '→' between them but only if both are specified. This is a piece of my code:

<span>

</span>

The t-if doesn't seem to be working. This attempt just gives me the '→' even if the chars aren't set.

How would I go about achieving my goal here?

Try to do this:

<field name="x_quote_pickup_city"/>
<field name="x_quote_delivery_city"/>    
<field name="x_quote_value"/>
<span t-if="x_quote_pickup_city.raw_value and x_quote_delivery_city.raw_value">
    <t t-raw="x_quote_pickup_city.raw_value"/> →
    <t t-raw="x_quote_delivery_city.raw_value"/>

</span>

I hope this works
