How to fix "Undefined Method total_pages"

I am setting up a search functionality in my Ruby On Rails application. I want users to search for a particular topic and be able to display the results. However, if there is no results pending, it should display a validation.

I have currently tried researching and adding different code such as adding @topic.paginate(:page => 1, :per_page => 2) and

trying this:

Topic.tagged_with(params[:tag]).order(created_at: :desc).page(params[:page]).per(3)

topics_controller: 

def index
 if params[:search].present?
   @topics = Topic.search(params[:search]).paginate(:page => params[:page], :per_page => 5)
   flash[:notice] = "No records found based on the search." if @topics.blank?
 else
   @topics = Topic.all
   flash[:notice] = "No records found in Database." if @topics.blank?
 end
end

index.html.erb:

<div> <%= will_paginate @topic, renderer: BootstrapPagination::Rails %> </end>

I expect as a validation message to appear. But instead, I have the following error:

**undefined method `total_pages'

Error Screenshot

I understand this error because of the pagination being added but not sure how to overcome this.

Maybe the problem is not your pagination but the else branch where you are not paginating @topics. Will_paginate can't create the pagination links.

def index
  if params[:search].present?
    @topics = Topic.search(params[:search]).paginate(:page => params[:page], :per_page => 5)
    flash[:notice] = "No records found based on the search." if @topics.blank?
  else
    @topics = Topic.all.paginate(:page => params[:page], :per_page => 5) #add this
    flash[:notice] = "No records found in Database." if @topics.blank?
  end
end
