Association of table to itself
I''m curious what would be the best way to represent people and whether the
person has someone marked as their friend.  Here are my thoughts so far:
People table
-  id
-  name
Relationships table
- person_id
- friend_id
Now my problem is I don''t know how to set up these associations (if this is
even correct).  Friend_id would be an id to someone else from the people
table.

Serialized object behaves weird
Hi!
I got a class named EinsatzFilter which I serialized to session. Before 
saving to session it works afterwards I keep getting the message: 
"undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from 
ActiveRecord::Base inherited class.
Code:
class EinsatzFilter
  include ApplicationHelper
  attr_reader :personen, :monat, :projekte, :kunde

ruby help / if (cond or cond)
Why this code doesn''t work as expected? It raises exceptions everytime. 
Tried with || operator, too.
validates_each :x, :y do |record, attr|
  record.errors.add (attr, ''between 1 and 100'') if (attr.to_i>100 or 
attr.to_i<0)
end

Validation on ActiveRecord destruction
Rails has many built in validation methods to ensure that an 
ActiveRecord instance cannot be created or updated under certain 
situations (typically caused by invalid data). However, I can find no 
methods to govern whether an ActiveRecord instance can be destroyed.
Essentially, I wish an error to be raised when a user tries to delete an 
ActiveRecord without first adhering to a certain set of

validate_on_destroy ?
What''s the best way to validate_on_destroy. Rails only seems to include
validate_on_create and validate_on_update methods. I don''t want to
resort to doing:
before_destroy do |j|
 raise "There is an error" if j.etc
end
Is there a way of finding out what action (create/update/destroy) is
being performed if I use the ''validate'' method?

How can I make has_many prevent a delete that would lead to orphans?
e.g.
class Asset < ActiveRecord::Base
  validates_presence_of :asset_number, :make, :model, :location,
:name, :serial_number
  validates_numericality_of :asset_number
  validates_uniqueness_of :asset_number
  belongs_to :user
  belongs_to :location
  belongs_to :asset_type, :foreign_key => ''type_id''
end
class Location < ActiveRecord::Base
  validates_presence_of :name

Conditional validations
I''ve been working with the problem that Joe Hosteny has been talking
about on this list and on the tickets he''s posted
(http://dev.rubyonrails.com/ticket/1196) and have come up with a
tentative solution that I''d like to bring up here.
What if we use a "conditional" parameter in the validates_* methods? 
Here''s how it would look like in practice:

Speeding up :dependent => :destroy
I have a tree of models that represent a book.  Looks like this:
book
   sections
      documents
          paragraphs
              index entries
              glossary entries
              footnotes
                  index entries
                  glossary entries
These are all models with has_many from parent and the child has
belongs_to.  They also all have dependent => :destroy

There is something I don''t understand about :dependent => :destroy. I

   has_many :group_folders, :dependent => :destroy
   validates_uniqueness_of :name, :scope => "folder_id"

Application Design
I have a question about how to implement a design in Rails.  I will try to make this as easy to follow as possible.  First, let''s say that I have an ''Orders'' table that has different statuses.  The 3 statuses that I want to track are ''Submitted'', ''Approved'', and ''Purchased''.  
I also have 3 users of this application.
