Rails - Jun 2013 - Contact form - NoMethodError (undefined method `each' for nil:NilClass)

Hi Guys,

So basically I want a contact form to appear on all the service pages.
I''ve already created a contact form for the contact page which works 
perfectly using this tutorial:
http://matharvard.ca/posts/2011/aug/22/contact-form-in-rails-3/

Now I would like to implement this approach on the service pages, and it 
works until I push the Submit button, when I get the following error:

Processing by ScontactController#create as HTML

Completed 500 Internal Server Error in 1ms

NoMethodError (undefined method `each'' for nil:NilClass):
  app/models/servicemail.rb:13:in `initialize''
  app/controllers/scontact_controller.rb:9:in `new''
  app/controllers/scontact_controller.rb:9:in `create''

The parameters are ok. 

Rails seems to complain about the each method in the model:
class Servicemail

  include ActiveModel::Validations
  include ActiveModel::Conversion
  extend ActiveModel::Naming

  attr_accessor :name, :email, :subject, :body, :szolg

  validates :name, :email, :subject, :body, :presence => true
  validates :email, :format => { :with => %r{.+@.+\..+} }, :allow_blank
=>
true
  
  def initialize(attributes = {})
    attributes.each do |name, value|
      send("#{name}=", value)
    end
  end

  def persisted?
    false
  end

end

This is the controller:
class ScontactController < ApplicationController

  def new
    @message = Servicemail.new
    @szolg = Service.find_by_permalink!(params[:id])
  end

  def create
    @message = Servicemail.new(params[:message])
    @szolg = Service.find_by_permalink(params[:id])
    
    if @message.valid?
      ServiceContact.new_message(@message).deliver
      redirect_to(szolg_path(@szolg), :notice => "Message sent 
successfully!")
    else
      flash.now.alert = "Please fill out all the required fields!"
      render :new
    end
  end

end


Is it the name of the model/view/controller that bothers Rails or is it 
something else?

Best Wishes,
Matt

That means that at that line of code you are calling ''each'' on
something that is nil.

Assuming that the above is line 13 then it means that attributes is nil.
