Not refresh after rotating the image using RMagick

I'm using rmagick to rotate my picture. So, basically when testing, after I invoked the rotate function and it executed successfully. I need to refresh the browser to see the result. That's normal.

So here come the question: when I move to controller method, after I invoked the function and make a redirect_to, it don't display the correct rotated picture. In case, I have to refresh my browser again to see the result. What possible that caused this issues?

my controller function is something like this:

def update
  @pic = Photo.find(params[:id]
  @pic.rotate_direction(90)
  redirect_to edit_photo_path(@pic)
end

My rotation function is working well. I suspect that caching is the problem, but when I use browser that don't save cache,it still remain the same result. Anyone faces this issues?

require 'RMagick'

def rotate
    photo   = Photo.find(params[:id])
    image   = Magick::ImageList.new(photo.file)
    image   = image.rotate(90)
    image.write(photo.file)

end
