Diagnosis: Whatever is defining your SourceParser module/class is not being required.

I agree with radar, you're attempting to reference something (impossible to tell from the snippet) with the SourceParser namespace that is not defined anywhere.

This snippet is at the end of source_parser.rb inside of app/models. There is a subfolder at app/models/source_parser/ with the class files, ical.rb, upcoming.rb, etc. These files are subclasses of source_parser. Is there a typical way of requiring these classes? Perhaps Rails/Ruby does it automagically? I can't find any trace of including them manually. Running 2.3.5, if it helps.

Does SourceParser inherit from ActiveRecord::Base? I like to keep non-ActiveRecord objects out of app/models and put them in the lib folder. Rails will include all class files in this directory by default.

Assuming SourceParser does not inherit from ActiveRecord::Base, I would put all your class files in lib and llose the folder hierarchy. So you'd have lib/source_parser.rb, lib/upcoming.rb, etc. If Upcoming, Ical and Hcal are subclasses of SourceParser, their class signature needs to look like "class Upcoming < SourceParser".

Does that help?

Nstamas you're incorrect about the signature of the class.

It needs to be defined as either:

class SourceParser::Upcoming

or

class SourceParser
  class Upcoming
  ...
  end
end

Or

module SourceParser
  class Upcoming
  ...
  end
end

Is SourceParser a class or a module? If it's a class and he's inheriting from SourceParser, he would use the "<" sig, if it's a module that the Upcoming, Ical, Hcal classes are included in, he'd use the "::" sig. Right?

for reference, I'm pulling code from http://github.com/calagator/calagator

I have cloned a copy of the Calagator project and am able to run it successfully on my machine. I've attempted to copy over just the components required for importing events, but clearly I've missed something, because it does not work in my project.

It appears that source_parser, and its siblings ical, upcoming, etc are classes.

source_parser.rb: http://github.com/calagator/calagator/blob/master/app/models/source_parser.rb

upcoming.rb: http://github.com/calagator/calagator/blob/master/app/models/source_parser/upcoming.rb

Try just moving source_parser.rb and the source_parser folder into the lib folder. The classes should then be included automatically by Rails.
