Further to the title, when loading data from ActiveRecord the encoding is always set to ASCII-8Bit in spite of my best efforts to force the encoding. I have entered as much detail as possible here to try and build a good error report someone could use to help me out!
The project is using the following technologies:

I have the following models but I cannot get the custom method reorder_action_items to work. I am obviously missing something basic.

}

Hi all,
I have this relationship in a Rails app
class Folder
has_many :elements
end
class Element
belongs_to :folder
end
My problem is this code doesn't work
element = Element.first
a_folder.elements << element
element.save!
a_folder.save!
, but this one works:
element.folder = a_folder
element.save!
Anyone can tell me why...

I just started exploring SubSonic 3's ActiveRecord, and it's initial code generation has created errors.
Cannot implicitly convert type 'int?' to 'int'.
An explicit conversion exists (are you missing a cast?)
Here's the line it throws the exception on:
public override int GetHashCode() {
return this.pkEmp;

I am trying to integrate with a Legacy table that has a column named "type".
Rails will "smartly" assume that whenever we have a 'type' column in a table, then it will try to use Single Table Inheritance.
Is there anyway to avoid this?
(I can't rename the column).

Hi,
In a MVC + ActiveRecord scenario, would it be possible/recommendable to validate db dependent properties as part of model binding? How would you go about implementing this - custom validation attribute?
A db dependent attribute could be active records ([Property(Unique=true)].
A simple example of its usage:

I have a model called Purchase and a model called TicketType. A purchase can have many ticket types, and a ticket type can have many purchases.
So I have

has_many :ticket_types, :through => :purchases_ticket_types
end

Hi,
I'm having trouble deleting from active record store.
I want to delete based on the session data:
ActiveRecord::SessionStore::Session.find(:all).each do |s|
if s.data[:userid] == 1234
s.destroy
end
end
does not seem to work, but:
ActiveRecord::SessionStore::Session.delete_all(["updated_at < ?", 12.hours.ago])

Suppose a column client_id is ubiquitous through out our database, and for a given session or request, we will be 'in the context' of a client the whole time.
Is there a way to simulate having each client's data stored in a separate database, while keeping them in the same table for simpler database-management ? What I want is similar ...
Let's say I have a FireNinja < Ninja object in my database, stored using single table inheritance. Later, I realize he's really a WaterNinja < Ninja. What's the cleanest way to change him to the different subclass? Even better, I'd love to create a new WaterNinja object and just replace the old FireNinja in the DB, preserving the ID.
