Manage friendship with parse

i'm trying to manage friendship using parse.com but i have some trouble because i usually use sql db. In parse i've a tab "user" and i'm using a column type relation that point to the same tab user. Is it correct?

Now i'm trying to add friend but appear this error:post 400 (Bad Request);

     var Models = {};

     Models.utenti = new Usercollection();
     Models.utenti.fetch({
       success: function(object) {
           console.log(object);
       },
       error: function(amici, error) {

       }
    }); 

    var amico=Models.utenti.get("xj3QLLYy07");        
    var user = Parse.User.current();
    var relation = user.relation("amici");
    relation.add(amico);
    user.save();

It is ok to make relation to the same table (User relation to User). If you want to add new user to relation of other user you can do it this way:

var curUser = Parse.User.current();

var userQuery = new Parse.Query(Parse.User);
userQuery.equalTo("objectId", "userId_you_want_to_add"); //xj3QLLYy07

//find the user you want to add
userQuery.first().then
(
    function(userToAdd)
    {
        var relation = curUser.relation("amici");

            //add user to relation
        relation.add(userToAdd);
        curUser.save();
    },
    function(error)
    {
        console.log("error: " + error.message);
    }
);

Hope this would help you.
