RSpec test failing looking for a new set of eyes

Here my issue: I\'ve got two models: class User < ActiveRecord::Base # Setup accessible (or protected) attributes for your model

Here my issue:

I've got two models:

class User < ActiveRecord::Base
  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :username

  has_many :tasks
end

class Task < ActiveRecord::Base

  belongs_to :user
end

with this simple routes.rb file

TestProj::Application.routes.draw do |map|

 resources :users do
  resources :tasks
 end
end 

this schema:

ActiveRecord::Schema.define(:version => 20100525021007) do

  create_table "tasks", :force => true do |t|
    t.string   "name"
    t.integer  "estimated_time"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.integer  "user_id"
 end

 create_table "users", :force => true do |t|
   t.string   "email"
   t.string   "password"
   t.string   "password_confirmation"
   t.datetime "created_at"
   t.datetime "updated_at"
   t.string   "username"
 end

 add_index "users", ["email"], :name => "index_users_on_email", :unique => true
 add_index "users", ["username"], :name => "index_users_on_username", :unique => true

end

and this controller for my tasks:

class TasksController < ApplicationController
  before_filter :load_user

  def new
    @task = @user.tasks.new
  end

  private

  def load_user
    @user = User.find(params[:user_id])
  end

end

Finally here is my test:

require 'spec_helper'

describe TasksController do

  before(:each) do
    @user = Factory(:user)
    @task = Factory(:task)
  end

  #GET New
  describe "GET New" do

   before(:each) do
      User.stub!(:find).with(@user.id.to_s).and_return(@user)
      @user.stub_chain(:tasks, :new).and_return(@task)
   end

   it "should return a new Task" do
      @user.tasks.should_receive(:new).and_return(@task)
      get :new, :user_id => @user.id
   end
 end
end

This test fails with the following output:

1) TasksController GET New should return a new Task
Failure/Error: get :new, :user_id => @user.id
undefined method `abstract_class?' for Object:Class

Can anybody help me understand what's going on here? It seems to be an RSpec problem since the controller action actually works, but I could be wrong.


I recreated your project from scratch using the information you supplied, and the controller spec runs without any failures (Rails 2.3.5, Ruby 1.8.7). So I'm guessing there's something amiss in your project and/or Rails configuration? Sorry, I know that isn't much to go on.


I recently got this error message with my Rails 3 app using rspec-rails 2.0.0.beta22 (under Ruby 1.9.2). After lots of hair pulling I upgraded to the recently releases rspec-rails 2.0.0.rc and the error disappeared. So, I'd recommend upgrading your rspec-rails gem.
