title: Django Filter get value from field
body: <p>How do I get the value from a field after a running filter?</p>
  <p><code>all_q_answered = ProjectQuestionnaireAnswer.objects.filter(response = q_response, answer__isnull=False)</code></p>
  <p>I need to get the values of the field <code>choice_weight</code> from the returned queryset?</p>
  <p>The <code>ProjectQuestoinnaireAnswer</code> model has a fk to a <code>Choices</code> model that has a choice weight value</p>
  <pre><code>class ProjectQuestionnaireAnswer(models.Model):
      YN_Choices = [
          ('Yes', 'Yes'),
          ('No', 'No'),
          ('Unknown', 'Unknown')
      ]
      question = models.ForeignKey(ProjectQuestionnaireQuestion, on_delete=models.CASCADE)
      answer = models.ForeignKey(Choice, on_delete=models.CASCADE,null=True)
      value = models.CharField(max_length=20, blank=True)
      notes = models.TextField(blank=True)
      response = models.ForeignKey(ProjectQuestionnaireResponse, on_delete=models.CASCADE)
  
  class Choice(models.Model):
      question = models.ForeignKey(ProjectQuestionnaireQuestion, on_delete=models.CASCADE)
      choice_text = models.CharField(max_length=200)
      choice_value = models.CharField(max_length=20, blank=True)
      choice_weight = models.IntegerField(blank=True, null=True)
  </code></pre>
  <p>Thanks</p>
