I am trying to add additional fields to the CarrierWave Uploader so that they are stored as part of the Uploader itself and together with the CarrierWave fields, such as @file, @model, @storage etc.
The fields are also version-specific, which is why I'd prefer to be able to access them via <my_model>.<my_uploader>.attribute and<my_model>.<my_uploader>.versions[:<the_version>] instead of additional columns in the model.
I did try the carrierwave-meta gem, but ran into an error with it ( NoMethodError: undefined method \'original_filename' for #<CarrierWave::Storage::Fog::File:0xab4134c> ) that seems to not have been fixed yet.
Any ideas or suggestions on how to best accomplish this?

I'm not 100% clear what you are trying to do.
when I use carrierwave gem, I do create a path that holds some of that information. In my applaications I normally have a file app/uploaders/image_uploader.rb
class ImageUploader < CarrierWave::Uploader::Base include CarrierWave::RMagick def store_dir # "uploads/image/file/187/" "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" end ... end from this I always know the model, what type of file, and the id. All other info about this model I normally save in the database.
I hope this helps and sets you in the right direction

your error is connected with fog
In my Picture Uploader I can set an attribute reader and writer
class PictureUploader < CarrierWave::Uploader::Base include CarrierWave::MiniMagick storage :file def field @field end def field=(field) @field = field end # attr_accessor :field # for an even shorter way end The I open the rails console to test the model:
picture = PictureUploader.new => #<PictureUploader:0x0055804db336e8 @model=nil, @mounted_as=nil> picture.field=('your text') => "your text" picture.field "your text" About the versioning and error you are having 'NoMethodError: undefined method \'original_filename' for #<CarrierWave::Storage::Fog::File:0xab4134c>' I agree with MZaragoza
CarrierWave::Storage::Fog::File.new takes three parameters
def store!(file) f = CarrierWave::Storage::Fog::File.new(uploader, self, uploader.store_path) f.store(file) f end uploader, self and uploader.store_path so to help us solve this problem you should include your CarrierwaveUploader model code and the output of uploader.store_path
Thanks a lot
