Moralis.Cloud.beforeSave is running twice

#1

Good day!

Why is the beforeSave being triggered twice whenever a transaction is made?

Moralis.Cloud.beforeSave("ItemsSold", async (request) => {

    const query = new Moralis.Query("ItemsForSale");
    query.equalTo("itemId", request.object.get('itemId'));
    const item = await query.first();
    if (item) {
        request.object.set('item', item);
        let x = Number(item.get("soldNFTs")) + Number(request.object.get('amount'))
        item.set('soldNFTs', x.toString());
        if (x.toString() === item.get("amount"))
            item.set('sold', true);
        await item.save();
    }
});

If you save the object in before save then that could be a reason. It could also enter an infinite loop if there is no check.

Another possible reason could be if the transaction is synced once as unconfirmed and once as confirmed

I still use the Syncs Events feature of Moralis Servers.

In the second reason, do you mean that it is also being triggered if the item is updated?

#4

It is triggered any time the item is updated

Usually you can use a flag to know if the code that you want to run was executed or not. You add a separate column in that table in order to store that flag
