Rails Hyperledger Blockchain Scaffold

My Rails 6 Hyperledger Fabric Blockchain CRUD Scaffold Using Ruby Hyperledger Fabric SDK.

Be Sure to Have a Working Hyperledger Installation:

Install VSCode with IBM Blockchain Platform Extension**:

• VSCode version 1.39
• IBM Blockchain Platform Extension for VSCode

Test Your IBM Blockchain Platform Extension:

• Click on 1 Org Local Fabric to start (Fabric Environment)
• Click on Package Open Project (Smart Contracts) after openning only app/contracts/users folder on VS Code
• Click on Fabric Environments -> Smart Contracts -> Installed -> Install and select node_blockchain_api_scaffold@0.0.1
• Click on Fabric Environments -> Smart Contracts -> Instantiated -> Instantiate and select node_blockchain_api_scaffold@0.0.1 use default values (press Enter) for all questions
• Click on 1 Org Local Fabric -> Org 1 -> right click -> Export Wallet and save on api/wallets (will create a folder called wallets on /api path)

Check That Everything is Working Before Using Rails:

• Click on Fabric Gateways -> 1 Org Local Fabric - Org1 and selecting admin
• Click on Fabric Gateways -> 1 Org Local Fabric - Org 1 -> Channels -> mychannel -> node_blockchain_api_scaffold@0.0.1 -> createUser -> right click -> Submit Transaction and send ["1", "Élisson Michael"] as argument (press Enter on next question) and you should see a "Successfully submitted transaction" notification
• Click on Fabric Gateways -> 1 Org Local Fabric - Org 1 -> Channels -> mychannel -> node_blockchain_api_scaffold@0.0.1 -> readUser -> right click -> Evaluate Transaction and send ["1"] as argument (press Enter on next question) and you should see a "Successfully submitted transaction" notification followed by [SUCCESS] Returned value from readUser: {"value":"Élisson Michael"} message on terminal
