Question

I’m trying to write a method to return true or false whether a product is actually in stock in a particular storage. I want to pass storage as parameter but receive an error through the console. What’s the right syntax?

def units_in_stock(storage)
  storage_id = Storage.find_by_id(storage)
  stocks.where("stock.storage_id = storage_id, in_stock > 0")
end

Answer 1

That should be:

where("stock.storage_id=? and in_stock>0", storage_id)

You could also use conditions.
