about `save` method and model's id

[class4cxy]

hi :

my question is after i call the model.save() method, how can i get the current model's id ? and mysql db is design to auto_increment. i was try to use "SELECT LAST_INSERT_ID() as id FROM " after save's callback, but it dosen't suit when concurrent request

Once the save callback has executed, the instance you created should have its id property correctly assigned.

thanks for reply. you means i can get the id from model instance ? like this ? var user = User.create(params); user.save(function () { alert(user.id) })

i found the insertId was return throught this.exec(sql, function (err, res) { ,but it dosen't return back to callback, why ? how could i get the insertId
