Warehouse Types are not unique by Name

[awjans]

The Warehouse Type can be repeated.

With organisation-specific warehouse types, type names need to be unique only within the organisation - although even then they should not collide with types with organisation_id=None (global types).

That said, I am not sure that organisation-specific warehouse types is a meaningful feature in the first place - I would prefer to drop it, and only enforce unique names.

I finally noticed the ‘deduplication’ functions in the UI.
But I agree that org-specific warehouse types are not a meaningful feature.

Right, so let's just remove org-specific warehouse types, and implement a simple IS_NOT_ONE_OF validation instead.

Hi, I’d like to work on this issue. I’m new to the project and would appreciate any guidance on where to start.

Thanks for assigning this to me!

Based on the discussion, I’ll proceed with removing organisation-specific warehouse types and enforce global uniqueness of warehouse type names using an IS_NOT_ONE_OF validation.

I’ll start by locating the model and current validation logic, then propose a patch shortly. Please let me know if you’d like me to also handle any existing duplicate records or focus only on preventing new ones.

I noticed that the current logic already enforces global uniqueness by name, but there are still a few commented-out references to the old organisation-specific warehouse type handling in inv.py.

Would you like me to remove those remaining commented references as part of this issue, and also verify that duplicate-name validation and deduplication still behave correctly?
