Can't upload the attachment

[Blackening999]

Hi

Pictures upload works like a charm, but when I try to upload an attachment/document I'm receiving this error:

NameError - uninitialized constant RedactorRails::Attachment:

I'm also getting this when trying to run

$  rails generate redactor:install --devise

Could not find "active_record/carrierwave/redactor/document.rb"...
