Rails 3联系表，未定义的方法？ [英] Rails 3 Contact Form, undefined method?

问题描述

我正在使用以下Railscast在Rails 3中建立联系表单： http：// railscasts.com/episodes/326-activeattr?view=asciicast

I'm building a contact form in Rails 3 using this Railscast: http://railscasts.com/episodes/326-activeattr?view=asciicast

我知道我唯一做错的就是填写消息应该在哪里被发送。我使用以下代码发送消息：

I know that the only thing I'm doing wrong is filling out where the message should be sent. I used the following code to send the message:

mail(:to => "[e-mail]") 

但是，这似乎不起作用，因为每次我提交表单时，都会出现此错误：

However, this doesn't seem to work, because everytime I submit the form, I get this error:

NoMethodError in MessagesController#create

undefined method `mail' for #<MessagesController:0x00000103734bd8>

Application Trace | Framework Trace | Full Trace
app/controllers/messages_controller.rb:10:in `create'

我应该用此行替换为发送消息吗？

What should I replace this line with to send the message?

messages_controller.rb

class MessagesController < ApplicationController

  def new
    @message = Message.new
  end

  def create
    @message = Message.new(params[:message])
    if @message.valid?
      UserMailer.contact_message(@message).deliver
      redirect_to root_url, notice: "Message sent! Thank you for contacting us."
    else
      render "new"
    end
  end

end

user_mailer.rb

class UserMailer < ActionMailer::Base

def contact_message(message)
@message = message
mail(:to => "[e-mail]", :subject => "New Message")
end

end

setup_mail.rb

ActionMailer::Base.smtp_settings = {
:address              => "smtp.gmail.com",
:port                 => 587,
:domain               => "mywebsite.com",
:user_name            => "myemail",
:password             => "secret",
:authentication       => "plain",
:enable_starttls_auto => true
}

ActionMailer::Base.default_url_options[:host] = "localhost:3000"

I just answered a similar question here: https://stackoverflow.com/a/17883328/307308

您丢失了 from 属性

mail(:from => '[e-mail]', :to => "[e-mail]", :subject => "New Message")
