Hi, Why are limited eager loads and conditions on the eager tables incompatible? Doing a find(:all) without :include causes a select * query to be generated, which means the id fields everwrite each other if associated tables are included using :joins. But using :include, if conditions are placed on the tables listed i...

Hey gang. Is it possible to extend the eager load SQL at all? What I''m hoping to do is eagerly load an associate that, in turn, joins in some data from another table.

Hi Trying to cut down on queries with eager loading and noticed the following in development.log Load IDs For Limited Eager Loading - SELECT id ....etc Followed by Load Including Associations - SELECT table.id ... etc Is this common practice? What is limted eager loading? Cheers Mark -- Posted via http://www.ruby-forum.com/.

Before I start, I''ve read the ActiveRecord docs on eager loading, but for the life of me, I can''t seem to get it working. What I mean by this, is that the eager query looks good (I can paste the sql dump, but it looks good to me - and runs well independantly), but it seems that I''m referencing the eagerly loaded data in a way that...

Polymorphic associations work great until I try to do some eager loading through :include. In my example, the interface name is ":imagehaver". Here''s my little eagerly loading find line: Image.find(params[:id], :include => :imagehaver) All it gives me is an ActiveRecord::EagerLoadPolymorphicError with no further explanation. I haven'&...

My problem is that I have two classes where the eager loading isn''t working as well as I would hope...

Hello. Using the ":include", which generates a "LEFT OUTER JOIN" SQL command, it is possible to eagerly preload second order data objects (children) for a given association. I wanted to know, if it is possible to eagerly preload and cache third order (or more) data objects, which are little-children or little-little-children. As I''ve seen. it is possible to add "LEFT OUTER JOIN"...

There is a dedicated section about eager loading in the docs. A coworker discovered eager loading does not work in polymorphic associations the hard way :-) so I''ve written a patch that documents it: http://dev.rubyonrails.org/ticket/10610 There are at least a couple of tickets that implement something that would chan...

I''m looking for someone to confirm the following as a bug in Rails 1.0 before I post it to Trac. If I use eager loading on an association that has conditions defined, the conditions are ignored. The following example illustrates the problem. I have two tables: create_table "blogs", :force => true do |t| t.column "name", :string end create_table "posts", :fo...

Hello everyone, I would like to eager load scoped records to avoid queries executed in a loop (huge performance impact). The "scoped" part is what is giving me a hard time. I''m using Rails3 RC.

...izing an object cause a namespace lookup? Are there any other side-effects of unserialize() that I should be cautious about? I've been digging through the R_Unserialize() call, I haven't found the loadNamespace bit yet but I assume its in there somewhere. Is there anyway to guard against R eagerly evaluating serialized data (serialize()) being unserialized (unserialize()) ? Thanks, Tyler [[alternative HTML version deleted]]
