Ruby on Rails

Rspec forum isn't working

Rspec is having trouble recognizing where method.

Here's the rspec output:

  NoMethodError:
       undefined method `where' for #<Article:0x000000066ceb38>
     #
/apps/rvm/gems/ruby-2.0.0-p481/gems/activemodel-4.0.10/lib/active_model/attribute_methods.rb:439:in
`method_missing'
     #
/apps/rvm/gems/ruby-2.0.0-p481/gems/activerecord-4.0.10/lib/active_record/attribute_methods.rb:168:in
`method_missing'
     #
/apps/rvm/gems/ruby-2.0.0-p481/gems/activerecord-4.0.10/lib/active_record/querying.rb:9:in
`where'


The spec calls index which then calls a public method that uses the
following method:

class X < ActiveRecord::Base
  def self.low_level
    where(:level=> 1)
  end
end

Any ideas what could be the problem?
