Can you share the code of the class Goalkeeper?

[jdnichollsc]

Try without using generics to inspect the response of the GET request

[mhadji05]

i update my code.

Basicly i need to make a DB on unity that every coach can save goalkeepers stats. One coach can have many goalkeepers and a goalkeeper can make many different stats for every training and i need to retrieve all of the stats of 1 goalkeeper.

Is that possible with RestClient and firebase?

[jdnichollsc]

Try this code:

firebaseTEST.cs

private void RetrieveFromDatabase()
{
    RestClient.Get(DB_URL + "goalkeeperK" + ".json").Then(response =>
    {
        Debug.Log(response.data);
    }).Catch(err => Debug.LogError(err));
}

[jdnichollsc]

Also, add a constructor without params like this:
Goalkeeper.cs

[Serializable]
public class Goalkeeper {
  public string keeperName;
  public int Totalstats;

  public Goalkeeper() {}

  public Goalkeeper(string keeperName, int Totalstats)
  {
    this.keeperName = keeperName;
    this.Totalstats = Totalstats;
  }
}

Try and let me know 👍

i have compile error

Assets/_Completed-Game/_FScripts/firebaseTEST.cs(47,32): error CS1061: Type Proyecto26.ResponseHelper' does not contain a definition for data' and no extension method data' of type Proyecto26.ResponseHelper' could be found. Are you missing an assembly reference?

[jdnichollsc]

@mhadji05 response.Data 😅

[jdnichollsc]

or response.Text

[mhadji05]

print null

[jdnichollsc]

ok, so that's your issue... 😅

[jdnichollsc]

Why not? You need a service to connect to the DB and retrieve data, maybe using FireBase Cloud Functions or creating a backend, later you can create the HTTP requests with this library to get the data of your service 👍

thanks a lot!
