Hi Bigos, You aren't using the view helper will_paginate gives you. It's as simple as:
@people = Person.paginate :page => params[:page] And in your view: <%= will_paginate @posts %> This will automatically generate the 'Previous' and 'Next' links. For further questions there is a dedicated will_paginate group at http://groups.google.com/group/will_paginate -- they'll be able to help you better! -- Evan On Feb 15, 2:53 pm, Bigos <ruby.obj...@googlemail.com> wrote: > I have a Persons table created with scaffold.
