Rails: activeadmin, undefined method `per' for #

Question

I installed ActiveAdmin successfully:

My gemfile code:

source \'https://rubygems.org\'

 gem \'rails\', \'3.2.10\'

 # Bundle edge Rails instead:
         


        

Answer 1

This worked for me:

initializers/will_paginate.rb

if defined?(WillPaginate)
  module WillPaginate
    module ActiveRecord
      module RelationMethods
        alias_method :per, :per_page
        alias_method :num_pages, :total_pages
        alias_method :total_count, :total_entries
      end
    end
  end
end
