Eager loading wierdness
Consider this problem. I have an Item that has_many Features I want to find all Items with a Feature name of ''foo''. Normally you would do this.. @items = Item.find(:all, :conditions=>["features.name = ?", ''foo''], :include=>:features) This all works fine and dandy except for this problem. If you do this... <% for item in @items %>

Can't eagerly load a polymorphic association defined in an STI parent class?
If I define an association (in my case a polymorphic one) in an STI parent class, and try to eagerly load it in a subclass, I get the following error: ActiveRecord::ConfigurationError: Association name ''myassoc'' was not found; perhaps you misspelled it? If I redefine the same association again in the STI subclass, it works. Is this a bug or what? -- You received this message

Migrations, data loads and changes to the model
Guys, I''ve run across an interesting scenario with my migrations, and I hope you might share some insight. Let''s say I have 3 migrations and two Models (Person and Car): 001_initial_schema.rb 002_data_load.rb 003_add_car_association.rb The first creates the initial schema...the second loads default data using model objects of Person to do so, and the third creates a new

Keep the Queries Down or "Referencing eagerly loaded models"
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 activerecord doesn''t

Problems with STI in has_many/belongs_to in Rails 1.1
I have a problem that surfaced in my attempt to upgrade my application to Rails 1.1. We have a STI model on the "belongs_to" side of a has_many/belongs_to relationship. All my unit tests for this model pass, and the relationships all seem to work fine. But in my functional tests, I''m getting errors. I''ve traced it back into the call to the has_many

Hi This looks like a bug in ActiveRecord. I am messing with eager loading (on 12.1) and all of a sudden records started disappearing from a table (and I am not doing anything delete related)!! The following line works OK:- @todos = Todo.find(:all, :include => [ :whens],:order => "position ASC") The following line is mysteriously deleteing :where rows from the DB after

Eager loading of ''is meant to be nil'' Associations
If I ''find'' using :include, and some included associations are null, then looping through the array executing ''if obj[i].assoc'' accesses the database for a second time (as obj.assoc is nil). eg Topic, has_many posts Post has_one email and posts = Post.find(:all, :condition => ''posts.topic_id = 10'', :include =>

Multi-page forms
I''m curious to see how others are dealing with the construction of multi-page forms. I can see a couple of ways to do this, each with their own advantages/disadvantates. Approach 1: * define one table with columns for each form entry. * define a method/view for each page, which only displays a subset of the fields. * submitting a page saves the data and moves on to the next page.

Issue with Observers and has_one association...
Hey Guys, I''m getting a peculiar bug working with Observers and has_one associations. When a has_one association is invoked by an Observer it always returns null. I looked in the development.log file and the SQL for the has_one association isn''t even being executed. On the other hand, when I replace the has_one association with just a hand crafted method, it does get called

Patch Review for selective joining of eager-loaded tables in pre-query
For those of you following the earlier saga of the performance of limited eager loading, I''ve decided to give up on pursuing my original patch. I received some support on the simplification argument (see my blog if you don''t know what I''m talking about), but it doesn''t seem like it''s worth breaking existing behavior. So I''m moving onto

Simple active record issue. I must be missing something.
Here''s a seemingly simple ActiveRecord use case. I have Projects and Users. Each project has a single team leader as well as a review team that consists of several users. I would like to use the same User model for authentication and just reference these users in my Project model. I tried this but got an "unknown column" error (for User.project_id) class Project has_one
