问题
After updating to Sail.js 0.10.1, I've been getting an error while trying to update attribute fields of a specific instance of a model. I've tried doing User.find() as well, then setting user.attribute = someValue, and then calling user.save(), and this very same error occurred.
Here is the relevant code:
// TODO: Save user params (for edit/updates)
save: function(req, res) {
var params = req.params.all(),
updateParams = {};
if (params['publicKey'] != '') {
sails.log.debug('Updating public key: ' + params['publicKey']);
updateParams['publicKey'] = params['publicKey'];
}
if (params['email'] != '') {
updateParams['email'] = params['email'];
}
sails.log.debug(updateParams);
User.update({ id: params['id'] }, updateParams, function (err) {
if (err) sails.log.error(err);
req.session.messages = { success: ['Successfully updated user profile'] };
if (req.session.user.admin) {
return res.redirect('/admin/manage_users');
} else {
return res.redirect('/');
}
});
},
The error that I get back is:
error: Error (E_UNKNOWN) :: Encountered an unexpected error

Some guidance would be much appreciated.
EDIT: I'm using sails-mysql.
EDIT: I turned on logging in my local MySQL database and monitored the query being executed. Here are the relevant lines:

My user model is defined as:

},
publicKey: {

},
// Instance methods
toJSON: function() {
var obj = this.toObject();
delete obj._csrf;
return obj;
}
updateParams: { publicKey: 'test2', email: '' }
params['id']: 991426

I think the issue here is that you don't have a primary key set for the model. Set primaryKey: true on the id field, and the error should go away. Thanks for the report; we'll probably want to patch Waterline to throw up a warning if you don't have primary key. And to, you know, not crash :)

I tested this using promises and postgres-sails, however this worked for me:
User.update(1, {emailAddress: 'test@test.com'}).then(console.log);
The only major difference is that I'm using Q promises here instead of callbacks.
