...record-3-eager-loading-fail#ticket-5845-19. There''s a small issue in Rails 3 eager loading, and this ticket has an accompanying patch. Sssociations that show up twice in a Relation chain like: Article.includes(:comments).includes(:comments => :moderations) will show up twice in the JoinDependency''s join_parts but only once in the query that gets run.

Having to construct this query manually (there are 4 joins) and still have a right format for eager association loading wasn''t really an option. I digged into ActiveRecord and modifying the JoinDependency class to output "STRAIGHT_JOIN"s instead of "LEFT OUTER JOIN"s looked like too much work too, so I decided to take a shorter route: intercept the generated sql query, and replace SELECT with SELECT STRAIGHT_JOIN. Here''s a monkey-patch (written against ActiveRecord 1.5....

My problem is that I have two classes where the eager loading isn''t working as well as I would hope... Here are my two classes: class Daynote < ActiveRecord::Base belongs_to :userplace class Userplace < ActiveRecord::Base has_many :daynote, :dependent => true When I show my userplaces, I want to get the associated daynotes with them, so I am doing: @userplace =

Dear all great developers. I wonder if there is any work being done or thoughts being shared regarding prepared SQL statements. Currently I am in heavy need of tuning SQL INSERTS that insert large (3MB) images into blobs. I am using rails 2.3.5 with postgres adapter and pg driver. Any information would be appreciated.
