如何使用django-treebeard实现树类型存储与编辑

pdm add django-treebeard

from treebeard.mp_tree import MP_Node
class CaseCategory(MP_Node):
    name = models.CharField('类别名称', max_length=100)
    node_order_by = ['name']
    def __str__(self):
        return '改装类别: {}'.format(self.name)
    class Meta:
        db_table = 'car_case_category'
        verbose_name = '改装类别'
        verbose_name_plural = verbose_name

from treebeard.admin import TreeAdmin
@admin.register(CaseCategory)
class CaseCategoryAdmin(TreeAdmin):
    form = movenodeform_factory(CaseCategory)
    list_display = ['name', 'depth']
    search_fields = ['name']

def seed_data_treebeard():
    from apps.car.models import CaseCategory
    get = lambda node_id: CaseCategory.objects.get(pk=node_id)
    root = CaseCategory.add_root(name='车衣')
    node = get(root.pk).add_child(name='亮面/光面')
    node = get(root.pk).add_child(name='磨砂/哑光')
    root = CaseCategory.add_root(name='改色')
    get(root.pk).add_child(name='纯色系')
    get(root.pk).add_child(name='渐变色')
    get(root.pk).add_child(name='定制彩绘')
    root = CaseCategory.add_root(name='改装')
    get(root.pk).add_child(name='轮毂')
    get(root.pk).add_child(name='刹车')
    get(root.pk).add_child(name='避震')
    root = CaseCategory.add_root(name='省心提')
