Django Admin: Customizing the inline template (tabular.html)

Question

I'm trying to follow the guidelines in this answer, but I'm getting stuck with how to edit the template.

The relevant part of my admin.py:

SegmentFormset = forms.models.inlineformset_factory(Division,Segment)
class DivisionForm(forms.ModelForm):
    def __init__(self, **kwargs):
        super(DivisionForm, self).__init__(**kwargs)
        self.segment_formset = SegmentFormset(instance=self.instance, data=self.data,
                prefix=self.prefix)

    def is_valid(self):
        return (super(DivisionForm, self).is_valid() and 
                    self.segment_formset.is_valid())

    def save(self, commit=True):
        assert commit == True 
        res = super(DivisionForm, self).save(commit=commit)
        self.segment_formset.save()
        return res

class DivisionInline(admin.TabularInline):
    model = Division
    form = DivisionForm
    template = 'competitions/admin/tabular.html'

class CompetitionAdmin(VersionAdmin):
    inlines = [DivisionInline,]

The relevant part of my template:

    {% for fieldset in inline_admin_form %}
      {% for line in fieldset %}
        {% for field in line %}
          <td class="{{ field.field.name }}">
          {{ field.field.errors.as_ul }}
          {{ field.field }}
          </td>
        {% endfor %}
      {% endfor %}
         <td>My segment formset should be here</td>
    {% endfor %}

What I can't figure out is how to access the segment formset. I've experimented with all of the variable names and none of them are my DivisionForm. The division formset is the {{fieldset.formset}} variable and that's as far as I've been able to get.

Edit 1:

Actually, the relevant part of the template is a bit longer ;) Putting in more code:

 <tbody>
 {% for inline_admin_form in inline_admin_formset %}
    {% if inline_admin_form.form.non_field_errors %}
    <tr><td colspan="{{ inline_admin_form.field_count }}">{{ inline_admin_form.form.non_field_errors }}</td></tr>
    {% endif %}
    <tr class="{% cycle row1,row2 %} {% if inline_admin_form.original or inline_admin_form.show_url %}has_original{% endif %}">

    <td class="original">
      {% if inline_admin_form.original or inline_admin_form.show_url %}<p>
      {% if inline_admin_form.original %} {{ inline_admin_form.original }}{% endif %}
      {% if inline_admin_form.show_url %}<a href="../../../r/{{ inline_admin_form.original_content_type_id }}/{{ inline_admin_form.original.id }}/">{% trans "View on site" %}</a>{% endif %}
        </p>{% endif %}
      {% if inline_admin_form.has_auto_field %}{{ inline_admin_form.pk_field.field }}{% endif %}
      {{ inline_admin_form.fk_field.field }}
      {% spaceless %}
      {% for fieldset in inline_admin_form %}
        {% for line in fieldset %}
          {% for field in line %}
            {% if field.is_hidden %} {{ field.field }} {% endif %}
          {% endfor %}
        {% endfor %}
      {% endfor %}
      {% endspaceless %}
    </td>

    {% for fieldset in inline_admin_form %}
      {% for line in fieldset.formset %}
        {% for field in line %}
          <td class="{{ field.field.name }}">
          {{ field.field.errors.as_ul }}
          {{ field.field }}
          </td>
        {% endfor %}
      {% endfor %}
      <td>My segment formset should be here</td>
    {% endfor %}

    {% if inline_admin_formset.formset.can_delete %}
      <td class="delete">{% if inline_admin_form.original %}{{ inline_admin_form.deletion_field.field }}{% endif %}</td>
    {% endif %}

    </tr>

 {% endfor %}
 </tbody>

Formsets are like lists, so you can recurse it like

{% for form in fieldset.formset %}
{{ form.as_p }}
{% endfor %}
