multer-gridfs-storage

问题 I have been trying to read the documentation for GridFS and MongoDB for awhile. They just keep repeating the same thing and I can't make sense of it. Desired Output: The user submits a form that form contains many fields, but one is an image. The request needs to store the data in a collection and make a new document, which can be retrieved later. My main question is how do I use GridFS in this situation to store an image in that document. It says GridFS makes two collections in my database

问题 Uploaded file using multer gridfs storage i want to reference it to newly created collection (movies). The fileID i referenced to the uploaded file is not the same with the uploaded file, even with that the movies collection is not saved on to the database. The fileID i referenced to the uploaded file is not the same with the uploaded file, even with that the movies collection is not saved on the database //movie schema const mongoose = require('mongoose'); const Schema = mongoose.Schema;
