title: How can i retrieve uploaded image (base64) full url from Carrierwave upload file to Rackspace?
body: <p>I just need to get the url of my image (base64) that just uploaded to Rackspace server via Carrierwave.</p>
  
  <p>This is my controller now.</p>
  
  <pre><code>def update_with_image
      user = current_user
      uploader = PictureUploader.new
      uploader.store!(user_update_params[:profile_image]) // base64 image like this 'data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2w...'
  
      // How can i update user_update_params[:profile_image] with the successfully uploaded profile_image url?
  
      if user.update_attributes(user_update_params)
        # Handle a successful update.
        render json: user, status: 200 ,serializer: UserSerializer
      else
        render json: { errors: user.errors }, status: 422
      end
    end
  </code></pre>
  
  <p>So after <code>uploader.store!(user_update_params[:profile_image])</code> how can i get the url of that file?</p>
  
  <p>Thanks!</p>
