A Strange Error.

[onurtvb]

Hello, i tried to look for something in the database to see if it existed, but if it already exists it gives me the error that you can see in the image below; I think it's a module error inside the tables, but I don't know.

The error happens in the

result = inventory.search(...)

You're passing a boolean to inventory.search(...), but Table.search expects a Query object, or a callable instead.
Most likely, you wanted to do something like (Note the uppercased "Inventory"):

Inventory = Query()
result = inventory.search(Inventory.name == "common_circle")
