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:

> <https://github.com/rails/rails/blob/main/activerecord/lib/active_record/attribute_methods.rb#L305>

Thanx a lot,

Tobi
