I’m getting the following console error: Typeerror: Cannot read Property '_id' of Undefined
I’m reading the book "Mean Full Stack Javascript..." from the code house. During the development of the application presented in the book, I obtained the above error. What I am trying to do is save or update a certain data in a list, for now static, on the server. However, after passing through Angularjs(routes and controller) and arriving in Express the controller receives the object sent as Undefined.
Giving a search, some places indicated take a look at the body-parser, but here it is all ok, based on the book and what the guys advised in other pots. However, I could not solve the problem. Follow the codes below:
HTML
<form ng-submit="salvar()" >
<div class="form-group">
<label for="nome">Nome Completo</label>
<input class="form-control" type="text" id="nome" name="nome" required ng-model="contato.nome">
</div>
<div class="form-group">
<label for="email">Email</label>
<div class="input-group">
<span class="input-group-addon">@</span>
<input class="form-control" type="text" id="email" name="email" required ng-model="contato.email">
</div>
</div>
<div>
<button type="submit" class="btn btn-primary">Salvar</button>
<a href="#/" class="btn btn-default">Voltar</a>
</div>
Controller Angularjs
var Contato = $resource('/contatos/:id');
$scope.salvar = function(){
$scope.contato.$save()
.then(function(){
$scope.mensagem = "Contato salvo com sucesso!";
$scope.contato = new Contato();
})
.catch(function(erro){
console.log(erro);
});
};
Rota Express
var controller = app.controllers.contatoController;
app.route('/contatos')
.get(controller.listaDeContatos)
.post(controller.salvarContato);
app.route('/contatos/:id')
.get(controller.obtemContatoPorId)
.delete(controller.remover)
.post(controller.salvarContato);
Controller Express
controller.salvarContato = function(req, res){
console.log("Chegou até salvarContato!");
var contato = req.body;
console.log(contato);
contato = contato._id ? atualiza(contato) : adiciona(contato);
res.json(contato);
}
In short. The object arrives in the express Undefined... I’ve reviewed the part of the book that explains about, I’ve looked on the net, until I gave up and came here. rsrs
Any help will be welcome!
Not to be left out, I also leave the body-parser configuration.
ps: the required module name is the same as the dependency in the package.json file
var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:true}));
Vlw!
Console expresses error on 5th line of Express Controller above.

Jokshan, if you like
console.log(JSON.stringify(contato));you can put the result here?– Sergio
Hello @Sergio ! The result is Undefined. I believe the object is not recovered when using req.body or it is not even being sent through the post request.

JSON.stringify(contato)should not give Undefined... What givesconsole.log(typeof contacto, contacto || 'vazio');?– Sergio
I identified and fixed the @Sergio issue, thanks for your attention!

Okay, if you want to put the solution in the answers. If it is not better to close/delete this question as no one else will know what the problem was nor the solution :)
