Description
Hi,
as I know, I can't use multiple columns for an idAttribute
this is useful for middel table on ManyToMany tables like below:
User Table:
- id ( Integer )
- username ( Text )
Group Table:
- id ( Integer )
- name ( Text )
Middle Table:
user_id ( Integer )
group_id ( Integer )
I want to use middle table for fetching user 1
I use idAttribute: "user_id, group_id" but it's not working
As most of the back-end storage methods don't support multiple primary keys, it doesn't make sense to implement in the core of Alloy. If a particular sync adapter implementation wants to, they can, but not in the core of alloy's code.
