total_pages return in pagination with rails and kaminari

Answer 1

try this

Old code

@services = @services.order(created_at: :desc).paginate(page:params[:page], per_page: 3 )

New code

@services = Service.order(created_at: :desc).paginate(page:params[:page], per_page: 3 )

Answer 2

I had a similar issue, it was because the commontator gem was bringing in methods from will_paginate and overriding the base ActiveRecord class.

The error was in the call stack for the page_entries_info method which seems to be a common method name between both libraries.

To fix, you can explicitly reference the method with this:

So the view code:

<%= Kaminari::Helpers::HelperMethods.page_entries_info @events %>
<%= link_to "Next", path_to_next_page(@events) %>
<%= link_to "Prev", path_to_prev_page(@events) %>

and in an initializer (initializers/kaminari_config.rb)

module Kaminari
  module Helpers
    module HelperMethods
      extend ActionView::Helpers::TranslationHelper
      module_function :page_entries_info
    end
  end
end

Try changing your controller code like the following:

class ServicesController < ApplicationController
    def index
      @organs = Admin::Organ.all
      @services = Service.order(created_at: :desc).page(params[:page]).per(3)
    end
end
