Hi,

did anyone ever ran into the problem that @attributes_cache being set
to nil somehow? That problems occurs running “rake spec” but not
running the single spec. The error occurs e.g. here:

github.com

rails/rails/blob/main/activerecord/lib/active_record/attribute_methods.rb#L305


      
          #   person.has_attribute?(:new_name) # => true
          #   person.has_attribute?('age')     # => true
          #   person.has_attribute?(:nothing)  # => false
          def has_attribute?(attr_name)
            attr_name = attr_name.to_s
            attr_name = self.class.attribute_aliases[attr_name] || attr_name
            @attributes.key?(attr_name)
          end
          
          
def _has_attribute?(attr_name) # :nodoc:
            @attributes.key?(attr_name)
          end
          
          
# Returns an array of names for the attributes available on this object.
          #
          #   class Person < ActiveRecord::Base
          #   end
          #
          #   person = Person.new
          #   person.attribute_names
          #   # => ["id", "created_at", "updated_at", "name", "age"]

Thanx a lot,

Tobi
