ruby-on-rails – 使用rails Mail_form gem时出错：“未初始化的

这是设置：我正在尝试为我公司的网站创建一个简单的潜在客户捕获表单.我希望将表单收集的数据通过电子邮件发送到我的电子邮件帐户而不需要数据库后端,我认为这就是mail_form会变得简单.

这是我的模型,ContactForm.rb：

class ContactForm < Mailform::Base
  attribute :name,:validate => true
  attribute :email,:validate => /A([w.%+-]+)@([w]{2,})z/i
  attribute :file,:attachment => true
  attribute :phone 
  attribute :referral
  attribute :message
  attribute :nickname,:captcha => true

  def persisted?
    false
  end

  def headers
    {
      :subject => "New Lead",:to => "jonthewineguy@gmail.com",:from => %("#{name}" <#{email}>)
    }
  end
end

这是我的控制器,contact_forms_controller.rb：

class ContactFormsController < ApplicationController
  def new
    @contact_form = ContactForm.new
  end

  def create
    begin
      @contact_form = ContactForm.new(params[:contact_form])
      @contact_form.request = request
      if @contact_form.deliver
        flash.now[:notice] = 'Thank you for your interest!'
        redirect_to root_path
      else
        render :new
      end
    rescue ScriptError
      flash[:error] = 'Sorry,something was wrong'
    end
  end
end

这是我的观点,contact_forms / new.html.erb：

<%= form_for @contact_form do |f| %>
 <div class="field">
   <%= f.label :name %>
  <%= f.text_field :name,:required => true %>(required)<br /><br><br>
 </div>
 <div class="field">
  <%= f.label :email %>
  <%= f.email_field :email,:required => true %>(required)
  <br /><br><br>
 </div>
  <div class="field">
  <%= f.label :phone %>
  <%= f.phone_field :phone %><br /><br><br>
 </div>
  <div class="field">
  How did you hear about us?:<br /> <%= f.text_field :referral
  %><br /><br><br>
 </div> 
  <div class="field">
  Comments (What types of wine are you
  interested in?):<br / <%= f.text_area :message %><br /><br><br>
</div>
 <div class="field">
  Submit: <%= f.submit "Create" %>
</div>

<% end %>

我对rails和Web编程一般都很陌生,所以很可能我错过了一些真正基本的东西,这在任何在线教程中都没有提到过.我已经遍历了mail_form文档以及我能找到的每个教程和答案,而且我仍然收到错误.

哦,是的！如果我在rails控制台中尝试ContactForm.new,我也会收到错误.任何帮助将不胜感激！

哦,是的,Rails版本3.1.1
