Rake task - undefined method - ruby-on-rails

Question

I tinkering my way into creating a rake task that grabs the amount of checkins for a given page throw facebook-graph. I usign the koala gem and rails.
I do this by creating a rake task:
task :get_likes => :environment do
require 'koala'
# Grab the first user in the database
user = User.first
# Loop throw every school & and call count_checkins
School.columns.each do |column|
user.facebook.count_checkins(column.name, user)
end
end
# Count like for every school else return 0
def count_checkins(name, u)
a = u.facebook.fql_query('SELECT checkins FROM page WHERE name = "' + name + '"')
if a[0].nil?
return 0
else
return b = a[0]["checkins"]
end
end
# Initialize an connection to the facebook graph
def facebook
#facebook ||= Koala::Facebook::API.new(oauth_token)
end
But I get a error:
private method `count_checkins' called for #<Koala::Facebook::API:0x007fae5bd348f0>
Any ideas or better way to code a rake task would be awesome!

Can't really format this properly in a comment, so I'll put it in an answer. I would put the following into the User model:
# Count like for every school else return 0
def count_checkins(name)
a = self.facebook.fql_query('SELECT checkins FROM page WHERE name = "' + name + '"')
if a[0].nil?
return 0
else
return b = a[0]["checkins"]
end
end
# Initialize an connection to the facebook graph
def facebook
#facebook ||= Koala::Facebook::API.new(oauth_token)
end
Then change the rake task to:
task :get_likes => :environment do
require 'koala'
# Grab the first user in the database
user = User.first
# Loop throw every school & and call count_checkins
School.columns.each do |column|
user.count_checkins(column.name)
end
end
That way count_checkins is defined on the user model, rather than trying to modify a class within Koala -- and you aren't duplicating work by having to pass around more User and Facebook parameters than are necessary.
