Message: [QUOTE="Rainer Jung, post: 4514680"] Hello there! I have a small problem. I am building an gallery-application with Rails. The model for the gallery is using "acts_as_tree" and "has_many :images". The image model "belongs_to :gallery" and "acts_as_list :scope => :gallery_id". I intended to use acts_as_list to be able to find all images in the same gallery-scope to simply paginate the images with ":per_page => 1". But now if i have the "@image", and try to get all other images, i would try to do "@image.parent.children". With .parent i would get the Gallery-instance, but if i use .children on that Gallery-instance, i probably would get the other Gallery-instances, which are in the subtree of the image. Has someone a nice idea how to easily paginate the images from one gallery? Regards, Rainer [/QUOTE]
