ruby on rails 3 - Carrierwave dynamic storage type via model attributes -


i want save photographs in 'grid_fs' , other types of files 'fog', like: 

class documentuploader < carrierwave::uploader::base   def storage     if model.is_photograph == true       :grid_fs     else       :fog     end    end end

is possible?

i want dynamically assign storage type model attributes, , i've tried this, model , attributes not accessible in class method.

thanks!

the quick answer "no". unlike store_dir, validate_integrity et al, storage isn't sent through add_config, , doesn't of instance-level magic make easy.

it might possible, come fragile hack. you're better off looking @ other ways support feature (multiple uploaders?) or changing specification.
