该deleteMany方法返回具有三个字段的对象：
n–匹配文件的数量ok–1如果操作成功，则为0deletedCount–删除的文件数
这与mongodbdb.collection.deleteMany方法的行为相同。
我建议你向模型添加静态方法：
// Assign a function to the "statics" object of our schema
categorySchema.statics.deleteManyWithSubs = async function(catIds) {
const deleteQuery = /*your delete query using catIDs*/
const delRes = await this.deleteMany(deleteQuery);
catIds.forEach(id => {
await subcategoryModel.deleteMany({ category: id })
});
return true;
};
// Usage
categoryModel.deleteManyWithSubs(ids)...

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
