Reusing form_for to view mail program errors while faking

Question

I have form_for in the new.html.erb template, where I do the usual save to the database, and then email when it succeeds. I want the mailer to send the same new.html.erb as the body and submit the model so that the form is completely filled. I get the following error:

undefined method `protect_against_forgery?' for #<#<Class:0x000000049d7110>:0x000000049d4690>

In the line immediately after the form_for tag (since I think it inserts the auth token token). Is there any way around this so that I can reuse the template in my inbox?

This is what the mailer code looks like

class MaintenanceMailer < ActionMailer::Base
  helper :application  

  def request_email(maintenance)
    mail :to => maintenance.community.email, :subject => "Maintenance" do |format|
      format.html { render :layout => 'default', :template => 'maintenance/new' }
    end    
  end
end
