Unknown Attribute Error

[Cricklewood]

Hi I'm trying to make a friend request feature like in a social networking site and I've
been getting this Unknown Attribute error whenever I try to request a friendship with an another user.

And this is the code of the friendship controller.

class FriendshipController < ApplicationController

	def req
		@user = User.logged_in(session)
		@friend = User.find_by_screen_name(params[:id])
		unless @friend.nil?
			if Friendship.request(@user, @friend)
				flash[:notice] = "Friendship with #{@friend.full_name} requested"
			else
				flash[:notice] = "Friendship with #{@friend.full_name} cannot be requested"
			end
		end
		redirect_to :controller => :user, :action => :index
	end
	
	def accept
		@user = User.logged_in(session)
		@friend = User.find_by_screen_name(params[:id])
		unless @friend.nil?
			if Friendship.accept(@user, @friend)
				flash[:notice] = "Friendship with #{@friend.full_name} accepted"
			else
				flash[:notice] = "Friendship with #{@friend.full_name} cannot be accepted"
			end
		end
		redirect_to :controller => :user, :action => :index
	end
	
	def reject
		@user = User.logged_in(session)
		@friend = User.find_by_screen_name(params[:id])
		unless @friend.nil?
			if Friendship.reject(@user, @friend)
				flash[:notice] = "Friendship with #{@friend.full_name} rejected"
			else
				flash[:notice] = "Friendship with #{@friend.full_name} cannot be rejected"
			end
		end
		redirect_to :controller => :user, :action => :index
	end
	

end

I am drawing a complete blank on how to approach with this error even when looking for some similar errors on google.

Thanks

Fixed. I simply forgot to put a colon in the Friendship model when I was setting up the request transaction. :)
