django - 美味派 - 在另一个 m2m 中删除 m2m

Question

我有 2 个相互具有外键的资源，例如：

class GroupResource(ModelResource):
    categories = fields.ToManyField(CategoryResource, 'category_set', 'categories', full=True)

    class Meta:
        queryset = Group.objects.all()


class CategoryResource(ModelResource):
    subcategories = fields.ToManyField(SubcategoryResource, 'subcategory_set', 'subcategories', full=True)

    class Meta:
        queryset = Category.objects.all()

当我列出它时，GroupResource它也会列出subcategories. 我怎样才能防止这种情况，只列出categories而不是subcategories？

Answer 1

根据您希望列出时包含的详细程度，您可以尝试设置full_list=False类别关系或使用full_list和full_detail子类别来更改输出。

Answer 2

只需添加use_in='list'到子类别中Category

class CategoryResource(ModelResource):
  subcategories = fields.ToManyField(SubcategoryResource, 'subcategory_set', 'subcategories', full=True, use_in='list')

  class Meta:
    queryset = Category.objects.all()
