rails faux active record - ruby-on-rails

Question

I am trying to use faux active record (a model that has no persistence in db).
I followed this example:
https://quickleft.com/blog/using-faux-activerecord-models-in-rails-3/
And I have this error:
ArgumentError in SearchController#new
wrong number of arguments (2 for 1)
app/models/search.rb:32:in assign_attributes'
app/models/search.rb:27:ininitialize'
app/controllers/search_controller.rb:4:in new'
app/controllers/search_controller.rb:4:innew'
It seems that when you call Search.new it needs the parametters but my goal is to make it an empty Search object.
Here are my model, controller, view, route:
Model
class Search
include ActiveModel::MassAssignmentSecurity
TRUE_VALUES = ActiveRecord::ConnectionAdapters::Column::TRUE_VALUES
attr_accessor :query
attr_reader :safe_search, :results_per_page
alias_method :safe_search?, :safe_search
attr_accessible :query, :safe_search, :results_per_page
RESULTS_PER_PAGE = [10, 25, 50, 100].freeze
include ActiveModel::Conversion
include ActiveModel::Validations
validates :query, presence: true
validates :results_per_page, presence: true, inclusion: { in: RESULTS_PER_PAGE }
def persisted?
false
end
def initialize(attributes = {})
assign_attributes(attributes)
yield(self) if block_given?
end
def assign_attributes(values, options = {})
sanitize_for_mass_assignment(values, options[:as]).each do |k, v|
send("#{k}=", v)
end
end
def results_per_page=(value)
#results_per_page = value.to_i
end
def safe_search=(value)
#safe_search = TRUE_VALUES.include?(value)
end
end
Controller
class SearchController < ApplicationController
def new
#search = Search.new
render "search/new.html.erb"
end
def create
#search = Search.new(params[:search])
# TODO: use the #search object to perform a search. Adding
# a `results` method on the search object might be a good starting point.
end
end
View: search/new.html.erb
<%= form_for #search do |f| %>
<%= f.label :query %>
<%= f.text_field :query %>
<%= f.label :safe_search %>
<%= f.check_box :safe_search %>
<%= f.label :results_per_page %>
<%= f.select_box :results_per_page %>
<%= end %>

Here is the solution that I found:
In the model I am using this:
def initialize(attributes = {})
assign_attributes(attributes)
end
def assign_attributes(attributes)
sanitize_for_mass_assignment(attributes).each do |k, v|
send("#{k}=", v)
end
end
Here are my new and create methods in the controller:
def new
#search = Search.new
render "search/new.html.erb"
end
def create
#search = Search.new(params[:search])
respond_to do |format|
format.html { render :template => "search/create.html.erb" }
end
end
By the way i had to rename my controller to SearchesController because controllers must be pluralized.
And here is my new.html.erb view:
<%= form_for #search, url: { action: "create" }, :method => :post do |f| %>
<%= f.label :query %>
<%= f.text_field :query %>
<%= f.label :safe_search %>
<%= f.check_box :safe_search %>
<%= f.label :results_per_page %>
<%= f.select(:results_per_page, [10, 25, 50, 100]) %>
<%= f.submit %>
<% end %>
I hope this will be useful to somebody.
