title: Many to many Field - Accessing attributes
body: <p>I have these two models related by a ManyToManyField:</p>
  
  <pre><code>class Bar(models.Model):
      name = models.CharField(max_length=25, blank=False)
  
  class Foo(models.Model):
  
      bar = models.ManyToManyField(Bar, blank=True, related_name='bb')
  
      def __unicode__(self):
          return '%s' % self.bar.name
  </code></pre>
  
  <p>In the admin page I get this error:</p>
  
  <pre><code>Exception Type: AttributeError
  Exception Value: 'ManyRelatedManager' object has no attribute 'name'
  </code></pre>
  
  <p>How can I access to the name of <em>bar</em> in <em>Foo</em>? I see the dot notation is not valid.</p>
