title: Sequelizejs findAll exclude field
body: <p>I know with <code>options.attributes</code> you list the attributes that you want to select
  but Is there a way to only exclude a field ?</p>
  
  <p>By now I worked it out with</p>
  
  <pre><code>User
    .findAll({order: [['id','DESC']]})
    .then(function(users) {
      users = users.filter(function(user){
        delete user.dataValues.password;
        return user;
      });
      return reply( ReplyUtil.ok(users) );
    })
    .catch(function(err){
      return reply( ReplyUtil.badImplementation(err) );
    });
  </code></pre>
  
  <h2>BTW</h2>
  
  <p>I don't understand why on earth you should use <code>user.dataValues.password</code>
  if not delete doesn't work instead of simply <code>user.password</code>
  if I debug like this <code>console.log('pass: ', user.password)</code>I can see the password.</p>
