Edit on Express outputing JSON to database field - json

Question

Trying to create my first simple CRUD in Express JS and I cant seem to find this annoying bug.
When I try to update a field, the JSON from that field, gets outputed to the view, instead of the new data.

The update method is used for finding and updating documents without returning the documents that are updated. Basically what you're doing is finding documents without updating them, since the first parameter of the update function is the search criteria. You need to use the save function to update an exiting document, after updating it's properties.
Your code below, modified (not tested):
//PUT to update a blob by ID
.put(function(req, res) {
//find the document by ID
mongoose.model('Email').findById(req.id, function (err, email) {
//add some logic to handle err
if (email) {
// Get our REST or form values. These rely on the "name" attributes
email.email = req.body.email;
email.password = req.body.password;
email.servico = req.body.servico;
//save the updated document
email.save(function (err) {
if (err) {
res.send("There was a problem updating the information to the database: " + err);
}
else {
//HTML responds by going back to the page or you can be fancy and create a new view that shows a success page.
res.format({
html: function(){
res.redirect("/emails");
},
//JSON responds showing the updated values
json: function(){
res.json(email);
}
});
}
});
}
});
})
