#storage(storage = nil) ⇒ Object Also known as: storage=

Sets the storage engine to be used when storing files with this uploader. Can be any class that implements a #store!(CarrierWave::SanitizedFile) and a #retrieve! method. See lib/carrierwave/storage/file.rb for an example. Storage engines should be added to CarrierWave::Uploader::Base.storage_engines so they can be referred to by a symbol, which should be more convenient

If no argument is given, it will simply return the currently used storage engine.

Parameters

storage (Symbol, Class)

The storage engine to use for this uploader

Returns

Class

the storage engine to be used with this uploader

Examples

storage :file
storage CarrierWave::Storage::File
storage MyCustomStorageEngine
