Shopware 6: how to prove if product has variants

Question

If I call a product, I will check if the product has variants.

Currently, I make it with an additional request using product.id

const criteria = new Criteria();
criteria.setLimit(1);
criteria.addFilter(
    Criteria.equals('product.parentId', this.product.id)
);
this.productRepository
    .search(criteria)
    .then((result) => {
        ...
    });

I can't find a suitable attribute (field) like e.g. product.hasVariant.

I think this is a simple parent:child relationship. I'm wondering if the only way to achieve this goal is in its children (which have the product.parentId field).

Question: — Is there an attribute, which define, if product has variants? — … or how to define, if a product has variants

Answer 1

Yes, there is a field called childCount.

JS:

criteria.addFilter(Criteria.range('childCount', { gt: 0 }));

API:

{
    "filter": [
        {
            "type": "range",
            "field": "childCount",
            "parameters": {
                "gt": 0
            }
        }
    ]
}
