Undefined method map

I have a rails 4 application that I'm trying to get to work with elasticsearch. Before I added the Elasticsearch, my code worked fine, but now I am getting this error:

undefined method `map' for nil:NilClass

My index view (I use haml):

= form_tag products_path, :method => :get do
  = text_field_tag :query, params[:query]
  = submit_tag "Search", :name => nil

= render "table"

and here is my _table partial:

- headers = @products.map(&:data).flat_map(&:keys).uniq

%table
  %tr
    - headers.each do |key|
       %th= key

  - @products.each do |product|
    %tr
      - headers.each do |key|
         %td= product.data[key]

My ProductsController#index

def index
  if params[:query].present?
     Product.search(params[:query])
  else
     @products = Product.all.where(:product_type_id => @product.id)
  end
end

My model:

class Product < ActiveRecord::Base
 include Tire::Model::Search
 include Tire::Model::Callbacks

 belongs_to :product_type

end

Thanks!

Looks like @products will be nil if there is a query present. I think you meant to do something like this:

  if params[:query].present?
     @products = Product.search(params[:query])
  else
     @products = Product.all.where(:product_type_id => @product.id)
  end
