Question

Here’s error and my codes. I’m using Kaminari

Error:  undefined method `model_name' for #<Array:0x0000001d5abeb0>
73:     <%= page_entries_info(@communities).html_safe %>

view

<%= page_entries_info(@communities).html_safe %>

Community controller

UPDATE* This is how I’m fetching now

    @search = Community.search do  
    fulltext params[:search]
        with(:location_id, params[:location]) if params[:location].to_i >0           
        with(:type_id, params[:type]) if params[:type].to_i >0
        order_by :cached_votes_up, :desc
        paginate :page => params[:page], :per_page => 10
    end

    @communities = @search.results

If you are using kaminari and will_paginate together, you will definitely face this error. In short, kaminari and will_paginate are incompatible to each other.

If you are using rails_admin (which uses kaminari for pagination) and also using will_paginate, you will need to add the following code to one of the initializers under config directory or you can create a new file, let say with name ‘will_paginate’ add the code, and place it into initializers directory.

if defined?(WillPaginate)
  module WillPaginate
    module ActiveRecord
      module RelationMethods
        def per(value = nil) per_page(value) end
        def total_count() count end
      end
    end
    module CollectionMethods
      alias_method :num_pages, :total_pages
    end
  end
end
