Ruby on Rails: Загрузка изображений в сторону от мобильных

Question

Я работаю над веб-приложением, которое использует CarrierWave и MiniMagick для обработки загрузок изображений для фотографий профиля аккаунта. Сейчас мой класс AvatarUploader выглядит следующим образом

class AvatarUploader < CarrierWave::Uploader::Base 

    # Include RMagick or MiniMagick support: 
    # include CarrierWave::RMagick 
    include CarrierWave::MiniMagick 

    # In the uploader: 
    def auto_orient 
    manipulate! do |img| 
     img = img.auto_orient 
    end 
    end 

    # Choose what kind of storage to use for this uploader: 
    # storage :file 
    # storage :fog 

    # Override the directory where uploaded files will be stored. 
    # This is a sensible default for uploaders that are meant to be mounted: 
    def store_dir 
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" 
    end 

    # Provide a default URL as a default if there hasn't been a file uploaded: 
    def default_url 
    ActionController::Base.helpers.asset_path('default_avatar.png') 
    end 

    # Process files as they are uploaded: 
    # process :scale => [200, 300] 
    # 
    # def scale(width, height) 
    # # do something 
    # end 

    # Create different versions of your uploaded files: 
    version :thumb do 
    process :auto_orient 
    process :resize_to_fill => [200, 200] 
    end 

    # Add a white list of extensions which are allowed to be uploaded. 
    # For images you might use something like this: 
    # def extension_white_list 
    # %w(jpg jpeg gif png) 
    # end 

    # Override the filename of the uploaded files: 
    # Avoid using model.id or version_name here, see uploader/store.rb for details. 
    # def filename 
    # "something.jpg" if original_filename 
    # end 

end 

и поле для обработки загрузки аватара в виде выглядит следующим образом

.row 
    - if f.object.avatar.present? 
    .field 
     = image_tag f.object.avatar.url 
    = f.input :avatar, label: f.object.avatar.present? ? 'Replace Avatar' : 'Avatar' 

Это все прекрасно работает на настольной версии моего сайта, но когда пользователь загружает профиль pic, который они берут со своего мобильного телефона, он поворачивается боком на 90 градусов, и я не могу понять, почему. Я думал, что добавление кода auto_orient из this question бы решить эту проблему, но это не

Фигурные его.

process :auto_orient 

должен быть вызван вне version: thumb do петли

exif image rotation issue using carrierwave and rmagick to upload to s3

попробуйте изменить метод auto_orient к этому:

def auto_orient 
    manipulate! do |img| 
    img.tap(&:auto_orient!) #try with and without the ! here. 
    end 
    end
