I used contextual filters before and I know they are just like the normal filters but more dynamic, now I have this view “Sidebar Product advert block” that needs to show the product advert ( Similar to product teaser! advert is a view mode ) BUT only if the product is referenced in the field_product_teaser in the article data type. So to be more clear:
Articles have a reference entity (Autocomplete) field_product_teaser.
Products referenced in this field should appear in the sidebar!
So the condition is {{ product.Product-id == article.field_product_teaser }}
I hope that was clear enough, what should I use in this case ?? contextual filters? relationships? I tried using both with no luck!
