My Document in MongoDb looks like:

{
    "_id" : ObjectId("5550e710dad47584cbfe9da1"),
    "name" : "Serverraum1",
    "tables" : [
                  {
                    "name" : "Table1",
                    "nummer" : "1",
                    "reihe" : "2",
                   }
               ]
}

Post Method:

app.post('/serverraeume', function (req, res) {
    console.log(req.body);
    db.serverraeume.update(req.body, function (req, res) {
    });
});

and the http post in angular controller:

$scope.addSchrank = function (serverraum){  
    $http.post('/serverraeume', $scope.table);
}

I want to update in the Document Serverraum1 tables. How can i push $scope.table in tables?

What's the object that's logged on console.log(req.body)? – chridam May 12 '15 at 7:43
    
for example: { name: 'Test', number: '2', row: '2' } – mk2015 May 12 '15 at 8:13

To update in the document serverraum1 tables by pushing $scope.table, the mongodb update function your POST method should use the $addToSet operator which adds a value to an array unless the value is already present, in which case $addToSet does nothing to that array:

app.post('/serverraeume', function (req, res) {
    console.log(req.body);
    var query = {"name" : "Serverraum1"}, // the query object to find records that need to be updated
        update = { "$addToSet": { "tables": req.body } }, // the replacement object
        options = {}; // defines the behaviour of the function
    db.serverraeume.update(query, update, options, function (req, res) {
        console.log(res);
    });
});
