I want to get the number of documents in the 'image' collection.
my code is
var express = require('express');
var mongoose = require('mongoose');
var bodyParser = require('body-parser');
var app = express();
app.set('view engine', 'ejs');
app.use(express.static(__dirname '/public'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:true}));
dburl = "mongodb srv://...";
mongoose.connect(dburl);
var db = mongoose.connection;
//...
var imageSchema = mongoose.Schema({
image_name:{type:String, required:true, unique:true}
});
var Image = mongoose.model('image', imageSchema);
var Dcount = db.image.countDocuments({});
but the console : enter image description here
CodePudding user response:
countDocuments()
is available directly on model
You should be doing Image.countDocuments()
Image.countDocuments({}, function (err, count) {
if (err){
console.log(err)
}else{
console.log("Count :", count)
}
});
