video_uploader.rb
class VideoUploader < CarrierWave::Uploader::Base
include CarrierWaveDirect::Uploader
alias_method :extension_white_list, :extension_whitelist
def will_include_content_type
true
end
default_content_type 'video/mp4'
allowed_content_types %w(video/mpeg video/mp4 video/ogg)
end
Model.rb
class Video < ActiveRecord::Base
mount_uploader :videosub, VideoUploader
end
Parameters:
"videosub"=>#<ActionDispatch::Http::UploadedFile:0x007f87201e28 @tempfile=#<Tempfile:/tmp/RackMultipart20170509-4704-1mjrwq.mp4>, @original_filename="168C7704-4337-A870-007B2CB22519.mp4", @content_type="video/mp4
Error showing is:
Validation failed: Videosub is invalid.
And if I replace the code inside VideoUploader as:
class VideoUploader < CarrierWave::Uploader::Base
include CarrierWaveDirect::Uploader
alias_method :extension_white_list, :extension_whitelist
storage :fog
end
Then the file is being successfully being uploaded to S3. But in my case I need to upload the video in background and directly to S3 bypassing the server on which the app is hosted.
Please help!
