trying to do a query session for Parse - ruby-on-rails

Question

using the gem parse-ruby-client and im trying to do a query session, here is my code.
im just curious on how to implement most of the https://parse.com/docs/rest/guide. Also i dont know if i created a session to begin with? i think the gem does it automatically? not too sure
class LoginController < ApplicationController
def index
end
def log_in
user = Parse::User.authenticate(params[:user][:username], params[:user][:password])
#username = params[:user][:username]
rescue Parse::ParseProtocolError
redirect_to :controller => "login"
end
def logout
Parse.client.post("https://api.parse.com/1/logout", {})
rescue Parse::ParseProtocolError
redirect_to :controller => "login"
end
def query_session
Parse.client.post("https://api.parse.com/1/users/", {})
end
end
here is log_in.html.erb
<h4>You are logged in as: <u><%= #username %></u></h4>
<%= link_to "logout", :controller => "login", :action => 'logout' %><br>
<%= link_to "test", :controller => "login", :action => 'query_session' %>
routes.rb
Rails.application.routes.draw do
root 'login#index'
get 'login/log_in' => 'login#log_in'
post 'login/log_in' => 'login#log_in'
get 'login/logout'
get 'login/query_session' => 'login#query_session'
end
this is my parse.rb
require 'parse-ruby-client'
Parselogin::Application.configure do
config.parse = Parse.init :application_id => 'APIKEY',
:api_key => 'APIKEY'
end
i get back this error when i click on 'test' button from the log_in.html.erb

You are missing the initialization of the Parse.client. This is an example from the gem's official documentation.
require 'parse-ruby-client'
client = Parse.create :application_id => '<your_app_id>',
:api_key => '<your_api_key>',
:quiet => true | false
To use the client later on, do the actions like this.
client.post("https://api.parse.com/1/logout", {}), where client is the variable from 1st snippet.
In order to respond to the second part of your question, please consider the gem's documentation.
