Self-referencing loop

[xorinzor]

I have 2 entities with a many-to-many relationship that I want to return via the API.
However, I only need the WithDetails to work 1 level down, subsequent items shouldn't be populated with their relationship data.

Right now my project apparently does just that, with a self-referencing loop as a result.
I followed this blog post but modified it so the relationship doesn't return the pivot table, but just the direct relationship instead.

How can I either: include the relationship 1 level down; or configure JSON to not follow a self-referencing loop?

The one page that supposedly would offer any info on JSON serialization seems to be incomplete.

Managed to find this to configure JSON Serialization settings.

That fixed my problem of the self-referencing exception.
