BackgrounDRb not working properly with files ?
Hey there, I''m kinda new to BackgrounDRb but I''m facing a big problem which I can''t seem to wrap my head around.

Inspired by Ryan Bates'' railscasts I was able to create A and D in the same form, and link A to B(created beforehand) through C in the same form as well. Is it possible to create A and B in the same form? Thanks in advance. -- Posted

has_many, :finder_sql, setting attributes
Hi all, My question is somewhat complicated, but bear with me. My project has a number of models: User, Program, and Team. Users belong to multiple Programs. Programs have multiple teams, but Teams belong to one program. For each Program a User belongs to, he can belong to multiple Teams. (Think of this in an athletic context where users are athletes, programs are universities). So my

rails 2.3 nested forms with has_many through checkboxes

Basically I have a page model, a page_category model and a category_items join table. Pages have many page categories through category items. The category_items table is polymorphic so i can use it for other models who need categories (maybe this is

Scope problem with form_remote_tag, ajax?
Hi all, I have tracked an odd behavior down to what I think is an issue of scope. In short, when I use form_remote_tag to establish an AJAX form, my database fields don''t get populated when performing an edit on the record. Those same fields will get populated using start_form_tag and no AJAX. I think that Ruby can''t find the local object that represents the database

Nested Forms with has_many associations with validations
I want to have a parent model that I can add child objects (via a has_many association) using the rails 2.3 nested form syntax. However, it seems like rails throws an error during validation of the parent model if I have a validates_presence_of :parent_id defined in the child model. Is the only solution to this to remove the validates_presence_of :parent_id? This seems like a hack-ish workaround.

Dynamic order on has_many relationship?
I was wondering if it''s possible to some how control the :order given on a has_many depending on another attribute? Or do I need to just create multiple has_many relationships pointing to the same table but with different orders and then select which one I use in the controller instead? e.g class Category < AR::B has_many :products, :order => //something magical?// end
