Question

I want to update a document using the inbound form fields from req.body without having to break them apart and build out a $set. I have this working just fine. Now I want to add an increment to a field that won’t be provided by req.body, how do I do that?

Here’s my current code:

var myproj = req.body; // grab req.body
myproj.foo = 'bar'; // some other random property

Project.update({_id: req.params.project_id }, myproj, { multi: false }, function(err, edited) {...

So how can I add a $inc to that for a field in the document called version ?

You can combine modifiers in the same update and you can apply your whole myproj in a single $set:

Project.update(
    { _id: req.params.project_id }, 
    { $set: myproj, $inc: { version: 1 } }, 
    { multi: false }, 
    function(err, edited) {...
