从一个用户发送消息到另一个

Question

我以为我在之前的文章中已经解决了这个问题，但是我仍然为此付出了努力。 在我的Rails应用程序中，我试图让用户能够在应用程序中发送消息（不通过电子邮件）。我使用的铁轨3.2.8和红宝石1.9.3p194

消息belongs_to的：用户

用户的has_many：消息

这是我在我的消息模型

def self.send_message(from, recipient) 
    recipient do |recipient| 
     msg = self.clone 
     msg.sent = false 
     msg.user_id = recipient 
     msg.save 
    end 
    self.update_attributes :user_id => from.id, :sent => true 
    end 

发送消息的方法

我试图做测试这种在轨控制台： Message.send_message（U2，U）

，其中U2 = User.find（1）& U = User.find（2）

我不断收到错误NoMethodError：未定义的方法`收件人为＃

我在做什么错？如何正确地向用户发送来自其他用户的消息。

如果有人有更好的方法，我愿意接受任何策略。

package com.bizibrush.action.login;

import javax.mail.Message; 
import javax.mail.MessagingException; 
import javax.mail.PasswordAuthentication; 
import javax.mail.Session; 
import javax.mail.Transport; 
import javax.mail.internet.InternetAddress; 
import javax.mail.internet.MimeMessage; 

public class GoogleTest { 

private static final String SMTP_HOST_NAME = "smtp.gmail.com"; 
private static final String SMTP_PORT = "465"; 
private static final String emailMsgTxt = "Test Message Contents"; 
private static final String emailSubjectTxt = "A test from gmail";

private static final String sendTo = "mailID"; 

/*public static void main(String args[]) throws Exception { 

Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider()); 

new GoogleTest().sendSSLMessage(sendTo, emailSubjectTxt,emailMsgTxt, emailFromAddress); 
System.out.println("Sucessfully Sent mail to All Users"); 
}*/ 

public void sendSSLMessage(String recipients, String subject, 
String message, String from) throws MessagingException { 
boolean debug = true; 

Properties props = new Properties(); 
props.put("mail.smtp.host", SMTP_HOST_NAME); 
props.put("mail.smtp.auth", "true"); 
props.put("mail.debug", "true"); 
props.put("mail.smtp.port", SMTP_PORT); 
props.put("mail.smtp.socketFactory.port", SMTP_PORT); 
props.put("mail.smtp.socketFactory.class", SSL_FACTORY); 
props.put("mail.smtp.socketFactory.fallback", "false"); 

Session session = Session.getDefaultInstance(props, 
new javax.mail.Authenticator() { 

protected PasswordAuthentication getPasswordAuthentication() { 
return new PasswordAuthentication("mailID", "password"); 
} 
}); 

session.setDebug(debug); 

Message msg = new MimeMessage(session); 
InternetAddress addressFrom = new InternetAddress(from); 
msg.setFrom(addressFrom); 

InternetAddress addressTo = new InternetAddress(); 
addressTo = new InternetAddress(recipients); 
msg.setRecipient(Message.RecipientType.TO, addressTo); 

// Setting the Subject and Content Type 
msg.setSubject(subject); 
msg.setContent(message, "text/plain"); 
Transport.send(msg); 
} 
} 

通过此代码，您可以通过gmail发送邮件。你应该添加lib文件
