MongoError: cannot change _id of a document

Asked By: Anonymous

I’m newbie to MongoDB and Backbone, so I try to understand them, but it is hard. I have a big, big problem: I cannot understand how to manipulate attributes in Backbone.Model to use in Views only what I need. More specific – I have a model:

window.User = Backbone.Model.extend({

    urlRoot:"/user",
    idAttribute: "_id",

    defaults: {
        _id: null,
        name: "",
        email: "[email protected]"
    }
});

window.UserCollection = Backbone.Collection.extend({
    model: User,

    url: "user/:id"
});

And I have a View:

beforeSave: function(){
    var self = this;
    var check = this.model.validateAll();
    if (check.isValid === false) {
        utils.displayValidationErrors(check.messages);
        return false;
    }
    this.saveUser();
    return false;
},

saveUser: function(){
    var self = this;
    console.log('before save');
    this.model.save(null, {
        success: function(model){
            self.render();
            app.navigate('user/' + model.id, false);
            utils.showAlert('Success!', 'User saved successfully', 'alert-success');
        },
        error: function(){
            utils.showAlert('Error', 'An error occurred while trying to save this item', 'alert-error');
        }
    });
}

I have to use ‘put’ method whit data from any fields except ‘_id’, so it must be smth like:

{"name": "Foo", "email": "[email protected]"}

But every time, doesn’t depend on what I do it send

{**"_id": "5083e4a7f4c0c4e270000001"**, "name": "Foo", "email": "[email protected]"}

and this error from server:

MongoError: cannot change _id of a document old:{ _id: ObjectId(‘5083e4a7f4c0c4e270000001’), name: “Foo” } new:{ _id:
“5083e4a7f4c0c4e270000001”, name: “Bar”, email: “[email protected]” }

Thanks in advance!

From looking at your mongo error, the problem is not with mongo, it is just doing what it’s supposed to do. It had an object with _id of ObjectId type: ObjectId(‘xxx’) and now you’re trying to change that object to have an _id of a String type (_id: “5083e4a7f4c0c4e270000001”) and that Mongo apparently does not like.

So, the question is: why did the object have an id of type ObjectId in the first place? How did you set it the first time? If you used some other method to initialize it (I’m guessing server side), you should set the id type to be a String so that it is the same as the one coming from your script library. If you want it to stay an ObjectId, you will need to convert the String coming from your script to an ObjectId before you save it to Mongo.

HTH.
