I have a page in which I display a list of products contained inside an order, and a button to add more products. I must keep this structure, which is working perfectly fine when I’m opening an existing order. However, when I’m trying to create a new order, the condition inside the ngIf
is undefined
, and so the check fails.
What’s the best way to handle such a case, to make it so that the definition of the value products
never fails or is there a better way to do it? In any case, how can I make it so that even if the order doesn’t have products
(or they’re undefined
), the div
gets shown anyway?
<div
*ngIf="
order
| map: 'product'
| products
| ngrxPush as products
"
>
<!-- Order info -->
</div>
