I need to use a rails app from C++. I say login in the title because that's one of my options. As far as I see it, I either need to do the standard login, and keep track of a session or something in the C++ code, or use an API token of sorts, and just pass that on every URL and never actually create a session on the rails side (which us...

Okay. So I have three models, a, b and c. a has_one c, b has_many cs, and c belongs_to both a and b. When I reference "cs" in a method of b, it comes out fine.
