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

[Máté Kaszás]

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
