Introduce a Getter for Arbitrator Policy Contract

[0xferit]

Scenario:

• Introduce a getter: function getPolicy(uint subcourtID) returns (string ipfsPath)
• In subgraph mapping, inside handleChallenge or handleDispute, call this getter and assign to courtEntity.

@0xferit can you please elaborate more, Do I need to make changes in arbitrators.sol?

Hello @Anurag-Raut ,

Kleros (dispute resolution provider, or simply arbitrator, in Truth Post) has sub-court policies, which are registered in this contract: https://goerli.etherscan.io/address/0x28c8A3A2E3c8Cd3F795DB83764316a1129a069bA#code.

1. Save this address in TruthPost during deployment, this is immutable. Note that for each network, there is only one arbitrator (thus one policy registry). So we can assume it won't change.
2. Introduce a getter function getPolicy(uint subcourtID) returns (string ipfsPath).

That's all. arbitrator. sol is not something we develop; it is solely for testing purposes.
