Hello,
can someone help, please, how to work with Active Record?
I''m trying under this page
-http://guides.rubyonrails.org/active_record_querying.html#retrieving-a-single-object
- building query on database, but I''m getting errors always, when I try
to use some command except .new, .save, .find, .all.
in application.rb I have:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "rails/test_unit/railtie"
in my model I have:
class Example < ActiveRecord::Base
include MongoMapper::Document
key :name
end
And now if I try:
exam= Example.order("name_at ASC") #--> undefined method
`spec'' for
nil:NilClass (that is in a view)
exam= Example.all
I guess everything for work with AR is ready, but I don''t now, why
commands as .order, .where, .first etc not works... :(
I''m using Rails 3.0.5 and MongoDB.

Skip straight pass the active record documentation and read up on mongomapper (or whatever mongo adapter you fancy using - mongoid is another popular one) Fred> > -- > Posted viahttp://www.ruby-forum.com/.-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks Fred, at least I know, what to search... I have that feeling I am solving problems with gems, plugins, interfaces instead programming of apps...
