Stack Level Too Deep Error In Rails - ruby-on-rails

Question

I'm getting this error in Rails and there's no other information to help me figure out why.
SystemStackError in UserController#students
stack level too deep
My user controller is as follows
class UserController < ApplicationController
before_filter :authenticate_user!, :except => [:show, :students, :mentors]
...
def students
#users = Student.where(:verify_code => 'VERIFIED')
end
end
Even when I remove the #users line the error persists.
EDIT: The error seems to happen to every single route aside from the devise_for :users and to_root, which means just the User controller.
User Model
require 'json'
require 'socket'
class User < ActiveRecord::Base
serialize :roles
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable

def valid_roles
valid_role_array = ['Top', 'Mid', 'Jungle', 'AD Carry', 'Support']
self.roles.each do |role|
unless valid_role_array.include?(role)
self.roles.delete(role)
end
end
end

return self.verify_code == 'VERIFIED'
end

self.summonerid = json['summonerId']
self.acctid = json['acctId']
self.verify_code = Array.new(10){rand(36).to_s(36)}.join

end
end
def eligible_to_mentor
leagues = shurima_api(self.server, 'leagues', self.summonerid)
unless leagues
errors.add(:ign, "That summoner doesn't seem to meet the requirements to become a mentor. Make sure you're at least in a Platinum League")
return false
end
leagues.each do |league|
if (league['queue'] == 'RANKED_SOLO_5x5')
self.tier = league['tier']
end
end
eligible_tiers = ['PLATINUM', 'DIAMOND', 'CHALLENGER']
if (self.type == 'Mentor' && !eligible_tiers.include?(self.tier))
errors.add(:mentor, "Mentors must be at least PLATINUM.")
end
end
def shurima_api(server, method, args)
host, port = 'ip removed', 714
TCPSocket.open(host, port) do |socket|
ready = IO.select([socket], [socket], nil, 8)
return false unless ready
socket.puts server + "&" + method + "&" + args.to_s
message = socket.gets.chomp
if message == '"Unknown error"'
return false
end
return JSON.parse(message)
end
end
end

I ended up fixing it by renaming the request method to request_mentor because it was causing the infinite loop.
