I''m having a problem with a has_and_belongs_to_many (habtm) association between two models with extra attributes. I''m writing a comic book database, and each issue has many creators on it. Thing is, some creators perform multiple duties. They may write one issue, draw another, etc. However, if I add a creator twice to an issue and try to delete it, it removes both creators: @issue.creators.delete(@creator) rabble from #rubyonrails suggested adding multiple habtm associatings in the Issue object. Here''s how they look: class Issue < ActiveRecord::Base has_and_belongs_to_many :creators has_and_belongs_to_many :writers, :class_name=>''Creator'', :association_foreign_key=>''creator_id'', :conditions=>''creator_job_id=1'' has_and_belongs_to_many :pencillers, :class_name=>''Creator'', :association_foreign_key=>''creator_id'', :conditions=>''creator_job_id=2'' has_and_belongs_to_many :inkers, :class_name=>''Creator'', :association_foreign_key=>''creator_id'', :conditions=>''creator_job_id=3'' has_and_belongs_to_many :colorists, :class_name=>''Creator'', :association_foreign_key=>''creator_id'', :conditions=>''creator_job_id=4'' has_and_belongs_to_many :letterers, :class_name=>''Creator'', :association_foreign_key=>''creator_id'', :conditions=>''creator_job_id=5'' class Creator < ActiveRecord::Base has_and_belongs_to_many :issues My join table looks like this: creators_issues issue_id INT creator_id INT creator_job_id INT If I use this code, it still deletes all instances of that creator: creator = @issue.writers.find(1) @issue.writers.delete(creator) Do I need to specify the Delete SQL statement for the habtm association? I haven''t seen sample code for it, so I''m assuming I specify the whole delete statement. Should all 3 fields in the join table be primary keys? Thanks for any insight anyone can provide on this matter... -- rick http://techno-weenie.net
