How to access property of a join resource in filter?

I have 2 resources in a many to many relationship through a 3rd join resource. However, this join resource has an additional boolean column. So now when I'm doing a

filter

filter

, how do I select only those related resources whose boolean is true or false in the

join_through

join_through

resource?

Solution

Nvm figured it out. Apparently this was exactly what the

parent()

parent()

expression is for https://hexdocs.pm/ash/expressions.html#many-to-many-relationships. I didn't know I had to give a custom name to my

join_relationship

join_relationship

or otherwise use the default

_join_assoc

_join_assoc

name when accessing this field
