Rails NameError uninitialized constant in has_many :through relation

I have the following models defined:

house_firm.rb

class HouseFirm < ActiveRecord::Base
  has_many :house_firm_group_links
  has_many :house_firm_groups, through: :house_firm_group_links
end

house_firm_group.rb

class HouseFirmGroup < ActiveRecord::Base
  has_many :house_firm_group_links
  has_many :house_firms, through: :house_firm_group_links
end

house_form_group_link.rb

class HouseFirmGroupLink < ActiveRecord::Base
  belongs_to :house_firm
  belongs_to :house_firm_group
end

However, when I do:

@house_firm = HouseFirm.new
@house_firm.house_firm_groups

I receive:

NameError at /house_firms/new

uninitialized constant HouseFirm::HouseFirmGroupLink

What am I doing wrong and how can I fix this?

You have a typo in the name of the file implementing HouseFirmGroupLink class, it should be named house_firm_group_link.rb.
