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.
