Migrating a skip already discounted items script
This looks like the easiest guard in the whole library and it is the hardest. The question it asks is about the other discounts running alongside it, not about the product, and that is a different kind of question entirely.
Limite di ShopifyIt skipped any line that had already been reduced by something else.
Incollalo in Recupero Script e guarda cosa ricostruisce
- Copia il Ruby con il pulsante accanto a ogni Script di questa pagina.
- Nell'admin di Shopify apri Stackable, poi Strumenti, poi Recupero Script.
- Incollalo lì, leggi cosa dichiara di costruire lo strumento e confrontalo con le impostazioni di questa pagina.
Recupero Script è nel piano Pro. Non viene pubblicato nulla finché non dichiari quanto scontava il vecchio Script e le due cifre non coincidono al centesimo.

Output.cart = Input.cartShopify cannot do this at checkout
Your Script checked whether an item had already been discounted by something else. Discounts at checkout all run at the same moment and cannot see each other's work, so that test could only ever be half right.
È un limite di Shopify, non una mancanza di Stackable. Oggi nessuna app di sconti riesce a ricostruirlo, ed è per questo che il link qui sotto porta alla documentazione di Shopify e non alla nostra.

Qui non c'è nessun carrello da testare, perché non viene creato nulla. Incollando questo compare il messaggio qui sopra e nessuna campagna.
