title: django manytomany - get value from through
body: <p>I have a manytomany field between 2 models:</p>
  
  <pre><code>class userProfile(models.Model):
      boughtCoupons = models.ManyToManyField(Coupon, through='UserCoupons')
  
  class UserCoupons(models.Model):
      user = models.ForeignKey(userProfile)
      coupon = models.ForeignKey(Coupon)
      date = models.DateField()
  
  
  class Coupon(models.Model):
      name = models.CharField(max_length=10)
  </code></pre>
  
  <p>Now my problem is:</p>
  
  <p>Given a coupon and a user ID, how can I get the date in which the user bought the coupon ?<br>
  Something like <code>mycoupon.boutcoupons.filter(user=userid)</code>  and then get the date somehow..</p>
  
  <p>Problem is that the field belongs to the user... and if I access the field from the user I get a list of coupons anyway, without the date.</p>
  
  <p>I just need the coupon-userID .date value.</p>
