Model Association issue in Rails

Question

Hopefully this will be simple. But I've hunted for a couple hours now and can't seem to get this to work. I have users who have multiple addresses, I'm trying to use Geocoder gem to display these users by a zip code search, my code is very similar to what is in the Geocoder Railscast.

Here's my controller attempt 1 and returns "undefined method `Addresses'"

def index
  if params[:search].present?
    @profiles = Profile.Addresses.near(params[:search], 25, :order => :distance)
    @title = "Therapists Near " + :search
  else
  @profiles = Profile.all
  @title = "Everyone"
  end
end

This is attempt number 2, this returns "uninitialized constant ProfilesController::Addresses" (I don't know if the Profile.where bit will work, but its not even getting to that part...)

class ProfilesController < ApplicationController

  def index
    if params[:search].present?
      addresses = Addresses.near(params[:search], 25, :order => :distance)
      @profiles = Profile.where(:id => addresses.id)
      @title = "Therapists Near " + :search
    else
    @profiles = Profile.all
    @title = "Everyone"
    end
  end

Here's my models:

class Profile < ActiveRecord::Base
  has_many :addresses, :dependent => :destroy
  accepts_nested_attributes_for :addresses, :reject_if => lambda { |a| a[:street].blank? }, :allow_destroy => true

class Address < ActiveRecord::Base
  belongs_to :profile
  geocoded_by :street
  after_validation :geocode, :if => :street_changed?

Thanks a lot for taking a look!

Answer 1

Additional, you may change to the following to get all profiles:

addresses = Address.near(params[:search], 25, :order => :distance)

@profiles = addresses.map{ |ad| ad.profile }.uniq unless addresses.nil?

If there are matched addresses, then find the profile from each address.

Answer 2

For number 2, you have to change from Addresses.near(params[:search], 25, :order => :distance) to Address.near(params[:search], 25, :order => :distance).

Answer 3

I found i couldn't paginate with the accepted answer. So I got pretty grubby:

addresses = Address.near(params[:search], 25, :order => :distance)
locations_id_array = []  
addresses.each do |address| 
  addresses_id_array << address.id
end  
@profiles  = Profile.where(:address_id => addresses_id_array).paginate(:page => params[:page],  :per_page => 5).order('name DESC')

If anyone has a nicer, scaleable way to do this (preferably with scopes) I'd love to hear it.
