### PART A

My altword_list template file receives a primary key ID from my Index template file.

#_______________________________________________________________________________

altword_list.html

<h1>{{ poll.rosword }}</h1>

{% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}

<h3>Filter 5</h3>

<ul>

{% for choice in poll.altword_set.all %}

<!-- for choice in poll.altword.all -->

    <li>{{ choice.rosword }}  = {{ choice.votes }} votes</li>

{% endfor %}

</ul>

### PART B

* Things work as intended when the rosword field just contain a simple "FK(Word)".

* But when I use the other rosword field instead containing "FK(Word, related_name='altword_rosword')", then

  my altword_list template file doesn't receive a primary key ID from my Index template file anymore.

What am I doing wrong when using related_name in my rosword field?

#_______________________________________________________________________________

class Altword(models.Model):

    #rosword = models.ForeignKey(Word, related_name='altword_rosword') # altword_list.html doesn't receive pk ID anymore why?

    rosword = models.ForeignKey(Word) # OK

    alt_ros_word = models.CharField(max_length=200)

    #wordy = models.OneToOneField(Word, related_name='wordy', primary_key=True)

    votes = models.IntegerField(default=0)

    def __unicode__(self):

        return self.alt_ros_word

#_______________________________________________________________________________

I have no idea what "primary key ID" has to do with anything. However, if you've changed the related name in the field, you should change it in the template as well:

  {% for choice in poll.altword_rosword.all %}
