I have a self-referential model of friends (based on Josh S.'s
tutorial), i.e. basically sthg like tables ‘people’ and ‘relationships’.
What I want is to display my friends together with their friends (and
possibly even deeper), some kind of tree
i.e. the output should look like this:
this must be pretty easy, but I’m a newbie and failed to google it out.

This could help:
has_many :through - Self-referential has_many :through associations
helped me, anyway.

Elisem, thank you.
actually I managed to implement the model, a variation on another Josh
Susser’s guidance at
has_many :through - Self-referential has_many :through associations.
If I use Josh’s example, I’d like to display a list of my ‘preys’
together with their ‘preys’ as well as their other ‘predators’ and also
my ‘predators’ as well as their ‘predators’ and their other ‘preys’.
I would be able to do that in SQL, but I’m a bit lost in the Rails
naming conventions in this case…
Thanks for any further help
