node.js - Mongoose update embedded document does not work -

greeting all,

i defined embedded mongoose model "person", contains field "contact", , "contact" has array of "address" person's work, home, delivery etc addresses.

when wanted update address, , utilize model's "save" function, alter wasn't reflected in database.

console.log(person.contact.address[i].city = 'chicago'); person.save(function (err) { if (!err) { console.log(person.contact.address[i].city);

the console.log indicates field city has been updated new value, mongodb's value stays same.

could please help me issue?

thanks! gary

the issue resolved using markmodified:

person.markmodified('contact.address'); person.save()

still not sure when need utilize markmodified, because in other cases alter reflected in mongodb without using it.
