uninitialized constant when running rspec test with concerns used in models

Question

When I run rspec spec/models/football_match_spec.rb I get an uninitialized constant error:

Type1Fixture concern:

module Type1Fixture
  extend ActiveSupport::Concern

  def competitors
    [competitor_1, competitor_2]
  end

  def competitor_1_score
    [fhhts || 0, shhts || 0, ethts || 0].reduce(:+)
  end

  def competitor_2_score
    [fhats || 0, shats || 0, etats || 0].reduce(:+)
  end

  def name_with_scores
    if [Fixture::IN_PROGRESS_STATUS, Fixture::COMPLETED_STATUS].include?(status)
      "#{competitor_1.name} #{home_team_score} - #{away_team_score} #{competitor_2.name}"
    else
      "#{competitor_1.name} vs #{competitor_2.name}"
    end
  end
end

Edited FootballMatch model:

class FootballMatch < Fixture
  include Mongoid::Document
  include Type1Fixture
end

I've added app/models/concerns to the config.autoload_paths array in environments/test.rb .

Answer 1

This can be caused by not having the correct file name. For Type1Fixture , the file containing the class should be called app/models/concerns/type1_fixture.rb . Is this the case?
