Rails 3: ActiveRecord .include not working

rubyonrails-talk

Really no idea what's up...

class Auction < ActiveRecord::Base   has_and_belongs_to_many :categories end

class Category < ActiveRecord::Base   has_and_belongs_to_many :auctions

  default_scope order('title')   scope :active, where(:active => true) end

class CategoriesController < ApplicationController   respond_to :html, :json

  # GET /categories/:id   def show     @category = Category.where(:id => params[:id]).include(:auctions).first     respond_with(@category)   end

end

I receive the error:

undefined method `include' for :ActiveRecord::Relation

I have tried this on simple has_many relationships as well, and I get nothing but this error when trying to use .include

its .includes not .include

Try following:

@category = Category.where(:id => params[:id]).includes(:auctions).first
