breaks has_one :through

[KevinMonk]

This is my first time posting an issue on any open source project so apologies if it's not done in the usual format.

I have a model like this:

class GradeGrade < ActiveRecord::Base
belongs_to :grade_item, :foreign_key => :itemid
has_one :moodle_course, :through => :grade_item ### This is broken by nested has many
end

In the console I could do the following:
g = GradeGrade.find(26)
g.moodle_course

It works fine without this plugin installed and shows this:
Mysql::Error: Unknown column 'mdl_course.grade_grade_id' in 'where clause': SELECT mdl_course.* FROM mdl_course WHERE (mdl_course.grade_grade_id = 26 )
when I install nested_has_many_through plugin.

Would love to help fix this but dont feel I have the expertise. Hope one of you bright chaps can help sort it out.

Regards,

Kevin.

Broke my has one too....

class Artist < User
has_many :agents_artists, :dependent => :destroy
has_many :agents, :through => :agents_artists
has_one :primary_agent, :through => :agents_artists, :conditions => ["agents_artists.primary_agent = ?",true] , :source => :agent

I got it working by using one of the other forks. I think it may have been JackDanger or logophobia. I can't remember which one now. There's a reference to it in one of the commit messages.

Thanks, yes, I checked out the lighthouse site for this plugin and someone mentioned that there was a fork that worked and it did.
