Parperclip exif wrong orientation from mobile upload

If ur image wrong orientation from mobile upload, u can add :source_file_options => { :all => '-auto-orient' }.

has_attached_file :image,
                    styles: { medium: "300x300>", thumb: "100x100>" },
                    :source_file_options => { :all => '-auto-orient' },
                    default_url: ->(attachment) { ActionController::Base.helpers.asset_path('tmp/a44.png') }

Some blog says it could be :convert_options => { :all => '-auto-orient' },but it dosen't work for me.

U can get exif info by follow those steps.

gem 'exifr'

EXIFR::JPEG.new(image.queued_for_write[:original].path)    /// in user model
