How to make methods for a boolean attribute?

How do I set a boolean to false in a method?

For my BusinessStore search I am trying to make 3 different radio buttons to choose from for Online Stores, Offline Stores and All Stores.

This my BusinessStore model and the 3 methods I am trying to make for the radio buttons:

attr_accessible :online_store # boolean attribute

def online_search
   business_store.online_store = true
end

def offline_search
   business_store.online_store = false
end

def all_search
   # Give all results whether true or false
end

How do I finish this and what needs to be corrected?

UPDATE

Product.rb

def search_type=(boolean)
   case (boolean)
    when 'online'
      @online_search = true
      @offline_search = false
    when 'offline'
      @online_search = false
      @offline_search = true
    when 'all'
      @online_search = true
      @offline_search = true
    else
    @online_search = true
    @offline_search = true
   end
end

search/index.html.erb

<%= label_tag :search_type, "All" %>
   <%= radio_button_tag :search_type, "all" %>
<%= label_tag :search_type, "Online" %>
    <%= radio_button_tag :search_type, "online" %>
<%= label_tag :search_type, "Offline" %>
    <%= radio_button_tag :search_type, "offline" %>

Took a different approach instead and just made two checkboxes:

SearchController.rb

def index
  @search = Product.search do
   q.with(:online_search, params[:online_search] == 1) if params[:online_search].nil?
   q.with(:offline_search, params[:offline_search] == 0) if params[:offline_search].nil?
  end
  @products = @search.results
end

search/index.html.erb

  <%= label_tag :online_search, 'Online' %>
    <%= check_box_tag :online_search, params[:online_search], true %>
  <%= label_tag :offline_search, 'Offline' %>
    <%= check_box_tag :offline_search, params[:offline_search], true %>

I set the checkboxes to start out as already checked for both in order to search online and offline unless one of them is unchecked. This is why in the search controller I search for the params being nil or not for both methods.

You'd probably have an easier time making a wrapper method that interprets the selection instead of having direct-mapped mutators:

def search_method=(value)
  case (value)
  when 'online'
    @online_search = true
    @offline_search = false
  when 'offline'
    @online_search = false
    @offline_search = true
  else
    @online_search = true
    @offline_search = true
  end
end

def online_search?
  @online_search
end

def offline_search?
  @offline_search
end

Then you make a selection between online, offline and all or whatever default you'd prefer.

Edit: Amended based on gist:

def index
  @search = Product.search do
    fulltext params[:search]
    paginate(:per_page => 10, :page => params[:page])
    order_by(:purchase_date, :desc)
    order_by(:price,:asc)

    includes(:business_store)
    where(:business_store => { :online_store => true })
  end
  @products = @search.results
end
