RSpec load_missing_constant, expected X to define Y (and it does)

When we run `bundle exec rake spec` it errors while trying to load the environment with the error: ``` ...gems/activesupport-3.2.8/lib/active_support/dependencies.rb:503:in `load_missing_constant': Expected ...app/models/links/category.rb to define Links::Category (LoadError) ``` The file `app/models/links/Category.rb` does indeed define `Links::Category`. Even stranger is that error does not occur when running under guard and spork (the standard way we run tests): `bundle exec guard -i` Runs the test suite as expected without issue. Spork is configured to run rspec, so I'm a bit confused about why running `rake spec` manually would cause this. I've seen similar issues which seemed to be solved by looking at the `autoload_paths`, and checking if it was including `lib` and `lib/**` however ours isn't doing anything funky with autoload_paths that I can see. Our `autoload_paths` looks like this (defined in application.rb): ``` config.autoload_paths += %W(#{Rails.root}/app/src #{config.root}/app/api #{Rails.root}/app/products) ``` (We're using `bundle exec rake spec` in our CI server to run the tests rather than guard which we use on our development machines). Does category.rb get loaded Added `puts 'Hey'` at the top of category.rb, and `puts 'Yo'` at the bottom, and when running the specs the output incldues it: ``` DEPRECATION WARNING: ActiveAdmin::Dashboard is deprecated and will be removed in the next version Hey Yo /Users/shimms/.rvm/gems/ruby-1.9.3-p125@lexim/gems/activesupport-3.2.8/lib/active_support/dependencies.rb:503:in `load_missing_constant': Expected /Users/shimms/Development/lexim/app/models/links/category.rb to define Links::Category (LoadError) ``` app/models/links/link.rb: ``` class Links::Link < ActiveRecord::Base self.table_name = 'links_category_links' attr_accessible :description, :name, :url, :category_id acts_as_paranoid belongs_to :category, :class_name => 'Links::Category' validates_presence_of :url validates_presence_of :name end ``` app/models/links/category.rb: ``` class Links::Category < ActiveRecord::Base self.table_name = 'links_categories' attr_accessible :description, :name, :space_id acts_as_paranoid extend FriendlyId friendly_id :name, :use => :scoped, :scope => :space belongs_to :space belongs_to_space(:space) has_many :links, :class_name => 'Links::Link' validates_presence_of :name end ``` spec_helper.rb ``` require File.expand_path('../../config/environment', __FILE__) require 'rubygems' require 'rails/all' require 'rspec/rails' require 'factory_girl' system "#{Rails.root.to_s}/db/test.db" ENV['RAILS_ENV'] ||= 'test' load_schema = lambda { load "#{Rails.root.to_s}/db/schema.rb" # use db agnostic schema by default # ActiveRecord::Migrator.up('db/migrate') # use migrations } silence_stream(STDOUT, &load_schema) Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f } RSpec.configure do |config| config.include FactoryGirl::Syntax::Methods config.mock_with :rspec config.fixture_path = "#{Rails.root}/spec/fixtures" config.use_transactional_fixtures = true ActiveSupport::Dependencies.clear end ``` **Simplest category_spec.rb that causes error*: ``` require 'spec_helper' describe Links::Category do pending "add some examples to (or delete) #{__FILE__}" end ``` Rake execution: ``` ➜ lexim git:(deveop) ✗ RAILS_ENV=test be rake spec --trace ** Invoke spec (first_time) ** Invoke db:test:prepare (first_time) ** Invoke db:abort_if_pending_migrations (first_time) ** Invoke environment (first_time) ** Execute environment Agent is configured to send raw SQL to the service Agent is configured to send raw SQL to the service DEPRECATION WARNING: Passing :tag, :class and others to use is deprecated.
