ruby on rails - CarrierWave Image URL -


i have model has:

    mount_uploader :image, imageuploader

when uploading image want retrieve width, height , exif data image. in before filter calling self.image.url return like:

/uploads/tmp/20110630-1316-10507-7899/emerica_wildinthestreets.jpg

the problem when try open image using:

image = minimagick::image.open(self.image.url)

i "no such file or directory - /uploads/tmp/20110630-1312-10507-6638/emerica_wildinthestreets.jpg". seems image has been moved tmp folder it's final location self.image.url not reflecting change.

i've tried in after_save method result same. ideas?

turns out needed append "#{rails.root.to_s}/public/" self.image.url
