There's sort of an example of this in the docs:
@entries = WillPaginate::Collection.create(1, 10) do |pager|
result = Post.find(:all, :limit => pager.per_page, :offset =>
pager.offset)
# inject the result array into the paginated collection:
pager.replace(result)
unless pager.total_entries
# the pager didn't manage to guess the total count, do it manually
pager.total_entries = Post.count
end
end
replace Post.find :all with a method that performs your query, using
the limit and offset passed to it and you should be fine. You may also
need to set pager.total_entries
