Getting nil class error in my rails app

Question

I am trying to pull images from the instagram API in my rails app and am currently getting an error:

undefined local variable or method 'search'

My view

<div class="container">
        <div class="row">
            <% search.each do |instagram| %>
            <%= image_tag instagram.images.low_resolution.url %>
            </div>
            <% end %>
        </div>

My controller

  class PagesController < ApplicationController

  def home
    access_token = "hidden"
    client = Instagram.client(access_token: access_token)
    default_search = client.tag_search('travel')
    search_query = client.tag_search(params[:q])

   if params[:q]
        search_query = client.tag_search(params[:q])
        @tag = search_query.present? ? search_query : default_search
    else
      @tag = tag.first.name
      @search = client.tag_recent_media(@tag)
  end

end

  end
end

Try this

In view

<div class="container"> 
  <div class="row"> 
    <% @search.each do |instagram| %>
      <%= image_tag instagram.images.low_resolution.url %>
     <% end %>
  </div> 
</div>

In controller

class PagesController < ApplicationController
  def home
    access_token = "hidden"
    client = Instagram.client(access_token: access_token)
    default_search = client.tag_search('travel')
    search_query = client.tag_search(params[:q])
    if params[:q]
     search_query = client.tag_search(params[:q])
     @tag = search_query.present? ? search_query : default_search
     @search = client.tag_recent_media(@tag)
    else
      @tag = default_search.first.name
      @search = client.tag_recent_media(@tag)
    end 
  end
end
