similar to: NameError: cannot remove Object::Elements

Hi, I just downloaded the latest rails, and tried to run webrick. I get this strange set of error messages. It looks like the real error is NameError: cannot remove Object::UnknownPropertyMethod I never had this problem with older versions, and the ''fastcgi'' variant, running under lighttpd runs fine. Any ideas why webrick appears to be broken? Thanks, David

Hello Rubyists, I am a bit stumped here. I want to extend the ''load_file'' method in the YAML module.

Is it possible to put conditions relative to the current instance in has_many''s :conditions? For example, in a forum app: class Post < ActiveRecord::Base belongs_to :topic has_many :self_and_descendants, :class_name => "Post", :order => "lft", :conditions => "topic_id = #{topic_id} AND (lft BETWEEN #{lft} AND #{rgt})" end With the

I moved from acts_as_tree to acts_as_nested_set because I need the all_children method. I''ve seen an alternative way to add this method to acts_as_tree here: http://www.chuckvose.com/articles/2006/05/24/recursive-children But I''d prefer to use the more efficient way of acts_as_nested_set (and not to have to revert to my old code). Anyway, here''s my issue: if I

I''ve searched for information about this and compared what I have to the solutions I can find, here and elsewhere. I found some good and useful information, yet my stuff still doesn''t work.

Hi guys, I''ve just installed Rails 2.3 and I am using the clearance plugin with cucumber features. When I run rake features I get this "uninitialized constant ActionController::AbstractRequest (NameError)" error from webrat trying to call AbstractRequest which now is called Request (I think).

I can''t seem to be able to override the :find method in the model base class, for example, in /lib/usermonitor.rb: module ActiveRecord module UserMonitor def self.included(base) base.class_eval do alias_method_chain :find, :user def current_site Thread.current[:user] end end end def find_with_user(*args) ... end end
