[Rails] Rails newbie can''t initialize a new Paginator object
Hi all,
I''m using ruby 1.8.2-15 and a recent rails 1.0 download.
I''m trying to implement the Classic/Custom pagination in a list action.
Here''s my code:
def list
getSearchTerms
# NOTE: @params[:search_results] is an Array of product_data objects
# returned by a search action.
@results = @params[:search_results]
if @results.nil? then
# The default list of all product_data
@product_datum_pages, @product_data = paginate :product_data,
:per_page => 10
else
page = (@params[:page] ||= 1).to_i
offset = (page - 1) * 10
# Note: ERROR OCCURS HERE
# I''ve tried both:
# ActionController::Pagenator.new and
# ActionController::Pagination::Paginator.new
# They don''t work either.
@product_datum_pages = Pagenator.new self, @results.length, 10,
page
@product_data = @results[offset..(offset + 10 - 1)]
end
end
When I try to run it, I get a "nameError: uninitialized constant"
exception from ruby. Basically, ruby can''t seem to load the Paginator
class. Looking at the library, this kinda makes sense, since Paginator
is actually defined in pagination.rb. Is this:
a) a RoR/ruby distro bug;
b) a configuration error; or
c) an application bug?
Thanks,
Larry

[Rails] Re: Rails newbie can''t initialize a new Paginator object
Take at look at this page: http://wiki.rubyonrails.org/rails/pages/ HowtoPagination In the code you sent, you misspelled "Paginator". That might be your problem.
