[odb-users] Querying entity's container

[Adnan RIHAN]

I need to find an entity based of one of it’s container’s data.

Let me explain, I’m on a CashRegister app.

I have the Product entity, which contains a Containers of String (QSet<QString>, unique in the table) to store the barcodes.
I have an Offer entity, which stores a Product and a Price.

I need to be able to find an Offer, using a barcode. So basically, except if it’s easily possible, I think I need to find a Product based on a barcode but I don’t see how to build the “odb::query<Product>” to find the Product which contains “barcode” in its container.

Is there a way, or do I need a workaround? Or suggestions?
Thanks
