Today I face with incorrect behavior in ActiveRecord. It take place when I try to use :include parameter for .find method. Where are two typical cases: 1. You have record with self-referential joins CREATE TABLE keywords (id, group_id); class Keyword < ActiveRecord::Base belongs_to :group, :class_name => "Keyword", :foreign_key => "group_id" end 2. Your record has two associations with the same table CREATE TABLE artworks (id, author_id, agent_id); class Artwork <...

I want to use a has_many through association to link the room and the users as such: class Room < ActiveRecord::Base belongs_to :group has_many :users, :through => :group end The SQL generated for the search is incorrect: SELECT users.* FROM users INNER JOIN group ON users.group_id = groups.id WHERE (groups.group_id = 2) The WHERE clause looks for group_id within the groups table when it should be looking for just id. It uses groups.id in the inner join, so I don''t understand why it is wrong in the WHERE clause. Do I need to specify something? Thanks in ad...

I''ve looked at the validates documentation and it appears that validates_uniqueness_of works on only one field at a time. So I can, for example, validate that "sam" is unique to the record set, and that "smith" is unique to the record set. My problem is that each record includes two fields, the _combination_ of which must be unique to the record set, but each of

So the queries will have to be restricted to those documents owned by the groups the user belongs to. I have a group_id in each record and the session has the group_id''s of the groups the user belongs to in an array. Question 1: If I add acts_as_ferret :fields => [:group_id, :document_text] can I do an activerecord search like... Document.find(:all, :conditions => [''group_id in (?)''...

Hi As we''re getting closer to a stable release of wxRuby, I''d like to get your views on the API style. There''s a survey here: http://rubyforge.org/survey/survey.php?group_id=35&survey_id=66 I''d like to know if you''d like to see two wxSugar syntax features become part of core, standard wxRuby version 2.0. These are: 1) Allow ruby-style accessors as well as C++ style getters/setters. This means you can write frame.title = ''my frame'...
