Json to Nested Models in Backbone.js

Question

Hello I have the following JSON provided from a server. With this I want to create a model with a nested model.

//json
{
    "2": {
        "sheet_id": 2,
        "distribution_id": 4,
        "areas": {
            "1": {
                "area_id": "1",
                "image_id": "164"
            },
            "2": {
                "area_id": "2",
                "image_id": "164"
            }
        }
    },
    "3": {
        "sheet_id": 3,
        "distribution_id": 4,
        "areas": {
            "1": {
                "area_id": "1",
                "image_id": "165"
            },
            "2": {
                "area_id": "2",
                "image_id": "164"
            }
        }
    },
}

I want these to be converted to two nested backbone models with the following structure:

Structure

Project has many Sheets and Sheet has many Areas

it's hardly possible to recognize what the structure you are expecting is and what you are exactly asking. — suish

The answer largely depends on how often this sort of pattern will repeat itself.

There is fantastic backbone classes that replace or augment the Model class which lets you do what you're looking for:

Of course you can also roll a 1-off solution in parse: method to manually init models or collections of the nested resources.

Thanks @Smazurov. And what do you recommend me? deep model or nested models? Did you use it with multiple nested classes?

Stepan Mazurov Over a year ago

I would probably go with Deep Model personally, but as suish mentioned in his comment, its entirely dependent on your project. The question does not have enough information to make an informed recommendation.

And what about collections? I was reading this post and may be is a native solution backbonetutorials.com/what-is-a-collection

Backbone collections are basically a way to do things with a list of models. You could represent each sheet in a Sheets collection.

You can also use this library,

Backbone Relational

You can create structure of models as you have mentioned using backbone relational.
