Add location_id and purchase_quantity to hunt mode

[llewy]

Thanks for this nice piece of python! Really like it.

Is there by chance, any way to add a couple of questions to the hunt mode? By example, every product uses the standard qu_id_stock from add_to_grocy.py which can't be changed in Grocy after first purchase. It would be nice if that ID can be entered in hunt mode.

Hey @llewy !

Thanks for using this code. I will try to implement your suggestion the coming week / next week. Since it's a while ago, that I wrote this I'll have to dig in to it again.

Nice! I've found a workaround by adding a column manually to the SQL-database and use data[] in the add_to_grocy. :-) But really no idea how to parse it in the index.py
