Node: check `boolean` value from defined `model`

I am trying to update position in my todo list

var Todo = mongoose.model('Todo', {         
text : String,
done : Boolean
});

database mode has two elements, and I want to update only boolean - done.

      app.put('/api/todos/:todo_id', function(req, res) {
      var query = { _id: req.params.todo_id }; 
            Todo.update(query,
                { done: true
                 }, function(err, todo) {
                    if (err)
                            res.send(err);
                    Todo.find(function(err, todos) {
                            if (err)
                                    res.send(err)
                            res.json(todos);
                    });
            });
    });

I would like to check actual value and then update. Done is from mongoose model so I can't check it like that? 

if (done != true){
done: true }
 else {
done: false }

Is something like that possible?

app.put('/api/todos/:todo_id', function(req, res) {
    Todo.findById(req.params.todo_id, function(err, todo) { // get todo by Model.findById
        if (err) return res.send(err);
        todo.done = !todo.done;                             // toggle todo's done field
        todo.save(function(err) {                           // save to database
            if (err) return res.send(err);
            res.json(todo);                                 // return the saved todo
        });
});
