Question

我试图将层次表显示为普通表。

model.py

class Dimension_value(MPTTModel):
    name = models.CharField(max_length = 200, null=True, blank = True, default = '')
    parent = TreeForeignKey("self", on_delete=models.CASCADE, null=True, blank=True, related_name="children")

    class MPTTMeta:
        order_insertion_by = ['name']

    def __str__(self):
        return self.name

views.py

def show_genres(request):
    return render(request, "accounts/dimension_detail.html", {'dimensions': Dimension_value.objects.all()})

dimension_detail.html

<div class="container-fluid">

    <div class="card">
      <div class="card-body">
  <h2>My dimensions</h2>

  {% load mptt_tags %}

<ul>
    {% recursetree dimensions %}
        <li>
            {{ node.name }}
            {% if not node.is_leaf_node %}
                <ul class="children">
                    {{ children }}
                </ul>
            {% endif %}
        </li>
    {% endrecursetree %}
</ul>

</div>

</div></div>

使用django-mptt，列表显示就很好。但是我不知道如何在普通表中显示它。

例如

欧洲|荷兰|北荷兰省
欧洲|荷兰|祖德-荷兰
欧洲|比利时|弗兰德森

我现在能得到什么
