我想将图片上传到指定的文件夹，并使用 mongoose 和 multer 模块。
我添加了var mongoose = require('mongoose');
var passport = require('passport');
var Project = require('../models/projects');
var multer = require('multer');
var ImageSavePath = multer({
dest: '../userFiles/projectImage',
rename: function (fieldname, filename) {
return filename.replace(/\W+/g, '-').toLowerCase() + Date.now();
});
}
module.exports = {
plain : function (req, res) {
//Datos cocinados con la respuesta...
if(!req.user){
res.redirect('/user/login');
}
res.render('project/resume', {
// resume page view parameters
title : "proyectos",
user : req.user,
});
},
create : function (req, res) {
//Datos cocinados con la respuesta...
if(!req.user){
res.redirect('/user/login');
}
res.render('project/create', {
// resume page view parameters
title : "Crear proyecto",
user : req.user,
projectName: "Nombre del proyecto",
image: "Subir imágen",
plane: "Subir plano en formato PDF",
details: "Detalles, información sobre el proyecto.",
ammount: "¿Cual es el coste de esto?",
location: "Localización",
});
},
saveProject : function (req, res){
ImageSavePath.array(req.body.image[5]);
var saveProject = new Project({
ProjectOwner : req.user._id,
ProjectName : req.body.projectName,
ProjectDetails : req.body.projectDetails
ProjectImagePath : ImageSavePath,
ProjectPdfPath : req.body.plane,
ProjectAmount : req.body.ammount,
ProjectLocation : req.body.localize,
});
saveProject.save(function(err){
if(err){
res.render('project/create', {
title: "La información no es válida, volver a introducir los datos",
});
}
});
},
}
如何在var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var project = new Schema({
ProjectOwner: String,
ProjectName: String,
ProjectDetails: String,
ProjectImagePath: [String],
ProjectPdfPath: String,
ProjectLocation: Number,
ProjectAmount: String,
});
module.exports = mongoose.model('project', project);
内将文件路径作为字符串？这是我的文件：
控制器/ projectController.js
var express = require('express');
var controller = require('../controllers/projectController');
var passport = require('passport');
var router = express.Router();
router.get('/', controller.plain);
router.get('/create', controller.create);
router.post('/create', controller.saveProject);
//router.get('/edit', controller.create);
//router.post('/create', controller.save);
//router.get('/delete', controller.delete);
module.exports = router;

app.use(logger('dev'));
app.use(bodyParser.json());

app.use(require('express-session')({

app.use(passport.initialize());
app.use(passport.session());
//Rutas express
app.use('/', index);
app.use('/user', users);
app.use('/project', projects);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handlers

部分解决
在create.jade模板中使用enctype="multipart/form-data"形式的是一个问题，如果没有这个，我可以将字段信息添加到req.body属性，例如req。 body.projectName，req.body.plane，req.body.details ...我需要解决enctype发生的事情，并将文件保存在数据库中保存的路径中。

<强>解决！
最后，我必须在 routes / projects.js 文件上更改上面的 multer ，并在上将req.file.path属性添加到ProjectImagePath > controllers / projectController.js 文件。
代码如下：
<强>路由/ projects.js
var express = require('express');
var controller = require('../controllers/projectController');
var passport = require('passport');
var multer = require('multer');
var router = express.Router();
var storage = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, '../userFiles/projectImage')
},
filename: function (req, file, cb) {
cb(null, "UploadedOn" + Date.now() + "fileOrigName" + file.originalname)
}
})
var upload = multer({ storage: storage});
router.get('/', controller.plain);
router.get('/create', controller.create);
router.post('/create', upload.single('image'), controller.saveProject);
//router.get('/edit', controller.create);
//router.post('/create', controller.save);
//router.get('/delete', controller.delete);
module.exports = router;
controllers / projectController.js 代码
saveProject : function (req, res, file){
var savingProject = new Project({
ProjectOwner : req.user._id,
ProjectName : req.body.projectName,
ProjectDetails : req.body.details,
ProjectImagePath : req.file.path,
//ProjectPdfPath : .plane,
ProjectAmount : req.body.ammount,
ProjectLocation : req.body.localize,
});
console.log("***start viewing content from req.body***");
console.log(req.body);
console.log("***start viewing content from req.file***");
console.log(req.file);
console.log("***start viewing content from savingProject variable***");
console.log(savingProject);
savingProject.save(function(err){
if(err){
console.log(err);
res.render('project/create', {
title: "La información no es válida, volver a introducir los datos",
});
}
if(!err){res.send('ok');}
});
},
console.log
