Django ORM returning the same values multiple times when using .distinct()
<p>When using <code>.distinct()</code> on a set of objects, the same values are being repeated over and over, which defeats the purpose of using <code>.distinct()</code></p>

<p>An example from a project I'm working on:</p>

<pre><code>In [5]: Section.objects.filter(module=15).values('section').distinct()
Out[5]: [{'section': '1'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, {'section': '2'}, '...(remaining elements truncated)...']
</code></pre>

<p>Why is it returning each value instead of only the distinct ones?</p>

<p>For reference, here is my model:</p>

<pre><code>class Section(models.Model):
    module = models.ForeignKey(Module, on_delete=models.CASCADE)
    title = models.CharField(max_length=400)
    section = models.CharField(max_length=3)
    topic = models.CharField(max_length=3)
    subtopic = models.CharField(max_length=3)
    subsubtopic = models.CharField(max_length=3)
    language = models.CharField(max_length=2)
    def __str__(self):
        return self.sectionid() + " - " + self.title
    def sectionid(self):
        return self.module.moduleid + ": " + self.justsectionid()
    def justsectionid(self):
        return self.section + "." + self.topic + "." + self.subtopic + \
        self.subsubtopic + "-" + self.language
    class Meta:
        ordering = ['section', 'topic', 'subtopic', 'subsubtopic', 'language']
</code></pre>
