How to load Firebase data to Graph Entity? Is there a way to modal the data? With Swift 3

I'm new to CosmicMind and have questions about the data process.

In the CosmicMind CardTableView Sample, the data are read from SampleData of Entity type.

Q1: Is there a way I can load my Firebase Data to Entity? And if so, how to do it? Looks like shouldn't be difficult, as it's JSON already. I'm using Swift 3.2

Q2: Is there a way to modal the Entity?

Thanks a lot!!

Welcome to CosmicMind :)

The easiest way would be to create an import function that takes in your JSON data and maps the key value pairs to properties in an Entity. If there is a type specifier in Firebase, then you can set that as the Entity type. I don't use Firebase, so I can't describe the setup 100%, but here is an example of what you would do, assuming Firebase gives you a unique ID.

func importFirebase(data: [[String: Any]]) {
    let graph = Graph()
    let search = Search<Entity>(graph: graph).for(types: "User")
    let users = search.sync()
    var index = [Int: Entity]()

    for user in users {
        if let id = user["id"] as? Int {
            index[id] = user
        }
    }

    for json in data {
        if let id = json["id"] as? Int {
            var entity: Entity

            if nil == index[id] {
                entity = Entity(type: "User")
            } else {
                entity = index[id]!
            }

            for (k, v) in json {
                entity[k] = v
            }
        }
    }

    graph.sync()
}

let data = [
    ["type": "User", "id": 1, "name": "Daniel", "age": 33],
    ["type": "User", "id": 2, "name": "Adam", "age": 28],
    ["type": "User", "id": 3, "name": "Sarah", "age": 23]
]

importFirebase(data: data)

This is not necessarily the optimal solution, it should give you an idea though.

Hope it helps, all the best!
