I've got a photo upload feature in my rails app. The app uploads direct to s3 through carrierwave via rmagick and fog. The issue I am having is when a photo is uploaded via mobile through the "take a photo option" in portrait (note this is with iphone but I believe android has the same issue). Once uploaded the image appears fine on mobile, however when viewed on desktop the image appears rotated 90 degrees.
Through my research it looks to be an issue with exif. This stackoverflow responder outlines 2 potential solutions. This gist also looks promising as well.
So far I have found a few solutions posted but none have worked. Ideally I would like the photo to be saved to s3 as a portrait, then just display the image as is.
Any suggestions are well appreciated.
Below is my code
class ImageUploader < CarrierWave::Uploader::Base
include CarrierWaveDirect::Uploader
include CarrierWave::RMagick
# Include the Sprockets helpers for Rails 3.1+ asset pipeline compatibility:
include Sprockets::Helpers::RailsHelper
include Sprockets::Helpers::IsolatedHelper
include CarrierWave::MimeTypes
process :fix_exif_rotation
process :set_content_type
version :thumb do
process resize_to_fill: [200, 200]
end
def extension_white_list
%w(jpg jpeg png)
end
def fix_exif_rotation #this is my attempted solution
manipulate! do |img|
img = img.auto_orient!
end
end
end
class S3Image < ActiveRecord::Base
attr_accessible :image, :name, :user_id
mount_uploader :image, ImageUploader
belongs_to :user
def image_name
File.basename(image.path || image.filename) if image
end
class ImageWorker
include Sidekiq::Worker
def perform(id, key)
s3_image = S3Image.find(id)
s3_image.key = key
s3_image.remote_image_url = s3_image.image.direct_fog_url(with_path: true)
s3_image.save!
s3_image.update_column(:image_processed, true)
end
end
end
CarrierWave.configure do |config|
config.fog_credentials = {
provider: "AWS",
aws_access_key_id: " ... ",
aws_secret_access_key: " ... "
}
config.fog_directory = " ... "
end
btw I used this Railscast as a guide for setting up my s3 upload.
Well I got this working using fog instead or carrierwave_direct.
Below is the code that ended up working for me:
app/uploaders/image_uploader.rb
class ImageUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
include Sprockets::Helpers::RailsHelper
include Sprockets::Helpers::IsolatedHelper
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
def fix_exif_rotation #this is my attempted solution
manipulate! do |img|
img.tap(&:auto_orient)
end
end
process :fix_exif_rotation
end
app/models/s3_image.rb
class S3Image < ActiveRecord::Base
attr_accessible :image, :name, :user_id, :image_cache
mount_uploader :image, ImageUploader
belongs_to :user
end
initializers/carrierwave.rb
CarrierWave.configure do |config|
config.fog_credentials = {
provider: "AWS",
aws_access_key_id: " ... ",
aws_secret_access_key: " ... ",
region: 'us-west-2'
}
config.fog_directory = " ... "
end
