MongoDB CRUD the MVC way with Passport Authentication 58 postmanSuccess Important to note is that in my case (with Postman) I had to add the Content-Type header (application/json) manually for the request. Find all users Great, so you created a new user in the users collection. In order to list existing users add the following code to your app/controllers/user.server.controller.js file: 1 exports.list = function(req, res, next) { 2 User.find({}, function(err, users) { 3 if (err) { 4 return next(err); 5 } 6 else { 7 res.json(users); 8 } 9 }); 10 }; Now you need to set up a route for this new method and in order to do so, go to your app/routes/users.server.routes.jsfile and change the app.route line to:
MongoDB CRUD the MVC way with Passport Authentication 59 1 app.route('/users').post(users.create).get(users.list); In order to test this run node server and enter http://localhost:1337/users¹¹² in your browser. Find one user So, previous functionality gives you the list of all the users, but in order to show only one specific user in the app/controllers/users.server.controller.js file add the following code: 1 exports.read = function(req, res) { 2 res.json(req.user); 3 }; 4 5 exports.userByID = function(req, res, next, id) { 6 User.findOne({ 7 _id: id 8 }, 9 function(err, user) { 10 if (err) { 11 return next(err); 12 } 13 else { 14 req.user = user; 15 next(); 16 } 17 } 18 ); 19 }; The read() method just responds with a JSON representation of the req.user object. The userById() method is populating the req.user object, which you will use as a middleware to deal with the manipulation of single documents when performing read, delete, and update operations. Now, modify your app/routes/users.server.routes.js file to look like this: ¹¹²http://localhost:1337/users
