ruby on rails - Pluralized many-to-many but still uninitialized constant -

as per below think setup fine:

class location < activerecord::base   has_many :traders   has_many :servicelocations   has_many :services, through: :servicelocations end  class service < activerecord::base     has_many :servicelocations     has_many :locations, through: :servicelocations end  class servicelocation < activerecord::base     belongs_to :location     belongs_to :service end  class trader < activerecord::base   belongs_to :location end 

the problem still getting uninitialized constant error.

i have noticed created model servicelocation, funky rails magic created service_location.rb unsure if a) problem , b) how fix if is.

i believe error came this

class service < activerecord::base     has_many :servicelocations     has_many :locations, through: :servicelocations end 

these should this

class service < activerecord::base     has_many :service_locations     has_many :locations, through: :service_locations # notice underscore end 

your model class name servicelocation , rails convention name service_location not servicelocation

and here also,you have change

class location < activerecord::base   has_many :traders   has_many :service_locations   has_many :services, through: :service_locations end
