.remove()类似于.find():

MyModel.remove({search: criteria}, function() {
    // removed.
});

如果你知道文档的_id，你可以使用findByIdAndDelete(id)，这是findOneAndDelete({_id: id})的简写。

import Question from '../models/Question';

const deleteQuestion = (questionId: string) => {
    try {
        Question.findByIdAndDelete(questionId);
    } catch (e) {
        console.error(e);
    }
};

这里的questionId是documentId (_id)

你可以直接在remove函数中使用查询，这样:

FBFriendModel.remove({ id: 333}, function(err){});

model.remove({title:'danish'}, function(err){
    if(err) throw err;
});

裁判:http://mongoosejs.com/docs/api.html # model_Model.remove

这招对我很管用，试试这个:

const id = req.params.id;
      YourSchema
      .remove({_id: id})
      .exec()
      .then(result => {
        res.status(200).json({
          message: 'deleted',
          request: {
            type: 'POST',
            url: 'http://localhost:3000/yourroutes/'
          }
        })
      })
      .catch(err => {
        res.status(500).json({
          error: err
        })
      });

我非常喜欢异步/等待功能的Express/Mongoose应用程序中的这种模式:

app.delete('/:idToDelete', asyncHandler(async (req, res) => {
  const deletedItem = await YourModel
    .findByIdAndDelete(req.params.idToDelete) // This method is the nice method for deleting
    .catch(err => res.status(400).send(err.message))

  res.status(200).send(deletedItem)
}))
