tastypie - 在另一个m2m内移除m2m

Question

我有两个互相拥有外键的资源，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GroupResource时，它还会列出subcategories。如何阻止，只列出categories而不是subcategories？

Answer 1

根据您在列出时所包含的详细程度，您可以尝试在类别关系上设置full_list=False，或使用子类别上的full_list和full_detail来更改输出。

Answer 2

只需将use_in='list'添加到Category

中的子类别即可

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

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