node.js - Post request work with one collection but not with the another using mongodb nodejs? -
i trying build simple rest api. firstly, have 2 collections books , genres. once post using postman in genres post no problems once post books collection post requesting time take 2 minutes(which consider much) return connection error knowing server remain working.
app
// tools used in web development var express = require('express'); var app = express(); var bodyparser = require('body-parser'); var mongoose = require('mongoose'); app.use(bodyparser.json()); genre = require('./models/genre.js'); book = require('./models/book.js'); let conn = mongoose.connection; conn.openuri('mongodb://localhost/bookstore'); conn.on('error', err => console.error('mongodb connection error', err)); conn.on('connected', () => console.info(`connected mongodb`)); conn.on('disconnected', () => console.info('disconnected mongodb')); // routing specific pages: app.get('/', function(req, res){ res.send('hello world'); }); app.get('/api/genres', function(req , res){ genre.getgenres(function(err, genres){ if(err){ throw err; } res.json(genres); }) }); app.get('/api/books', function(req , res){ book.getbooks(function(err, books){ if(err){ throw err; } res.json(books); }) }); app.get('/api/books/:_id', function(req , res){ book.getbookbyid(req.params._id, function(err, book){ if(err){ throw err; } res.json(book); }) }); app.post('/api/genres', function(req , res){ var genre = req.body; genre.addgenre(genre, function(err, genre){ if(err){ throw err; } res.json(genre); }) }); app.post('/api/books', function(req , res){ var book = req.body; book.addbook(function(err, book){ if(err){ throw err; } res.json(book); }) }); //specify listening port app.listen(3666); //display url on termianl console.log('server running on http://localhost:3666'); book
var mongoose = require('mongoose'); //book schema var bookschema = mongoose.schema({ title:{ type: string, requires: true }, genre:{ type: string, required: true }, description:{ type: string }, author:{ type: string, required: true }, publisher:{ type: string, required: true }, create_date:{ type: date, default: date.now } }); var book = module.exports = mongoose.model('book', bookschema); module.exports.getbooks = function(callback, limit){ book.find(callback).limit(limit); } module.exports.getbookbyid = function(id, callback){ book.findbyid(id, callback); } //add genre module.exports.addbook = function(book, callback){ book.create(book, callback); } 
and database
notice: once post request in genres works once post book nothing happen.
your addbook function takes 2 parameters: book object , callback
//add genre module.exports.addbook = function(book, callback){ book.create(book, callback); } but, while calling it, have passed callback. can try use below code:
app.post('/api/books', function(req , res){ var book = req.body; book.addbook(book, function(err, book){ if(err){ throw err; } res.json(book); }) });
