Name Error - uninitialized constant Rails - ruby-on-rails

Question

I'm adding search functionality to my ruby on rails app. Based on the Ryan Bates tutorial #111.
For some reason, my render call in my show page is resulting in
Name Error
uninitialized constant Search::Properties
My controller is simple
class SearchesController < ApplicationController
def new
#search = Search.new
end
def create
#search = Search.create(search_params)
redirect_to #search
end
def show
#search = Search.find(params[:id])
end
private
def search_params
params.require(:search).permit(:keywords, :category, :min_price, :max_price, :bedrooms, :bathrooms, :garage)
end
end
And I created a new class in my model
class Search < ActiveRecord::Base
def properties
properties = Properties.all
properties = properties.order(:title)
properties = properties.where(["title LIKE ?","%#{keywords}%"]) if keywords.present?
properties = properties.where([category: category]) if category.present?
properties = properties.where(["price >= ?","%#{min_price}%"]) if min_price.present?
properties = properties.where(["price <= ?","%#{max_price}%"]) if max_price.present?
properties = properties.where(["bedrooms == ?","%#{bedrooms}%"]) if bedrooms.present?
properties = properties.where(["bathrooms == ?","%#{bathrooms}%"]) if bathrooms.present?
properties = properties.where(["garage == ?","%#{garage}%"]) if garage.present?
properties
end
end
And my view
<div class="row property-list-wrapper">
<div class="container">
<div class="col-md-8 property-list-left">
<h1>We've found <%= pluralize(#properties.count, 'property')%> </h1>
<%= render #properties %>
</div>
<div class="col-md-4 property-list-right">
</div>
</div>
</div>
It seems that my render tag is not finding the class in my model. Am I missing something in my controller maybe?
I'm using rails 4.2.7 and ruby 2.2.4p230
