Upload file with api and carrierwave. ruby-on-rails,ruby,api,carrierwave. Basically it is based on the tool which is used by the API consumer. If API consumer is using ruby then can consume it by passing File object, or using httmultiparty gem we can upload the file. This makes reuploading the file from one storage to another really natural. Furthermore, this allows the storage to optimize some uploads by skipping downloading & reuploading, for example use an S3 copy if both files are from S3, or just send the remote URL if the storage supports it. CarrierWaveDirect. CarrierWave is a great way to upload files from Ruby applications, but since processing and saving is done in-process, it doesn't scale well. A better way is to upload your files directly then handle the processing and saving in a background process. CarrierWaveDirect works on top of CarrierWave and provides a simple way to achieve this.
