Problem loading Smart Contract #146

Closed AlbertoHdezCerezo closed 4 years ago

AlbertoHdezCerezo commented 4 years ago

Hi, first of all thank you for your contribution with this awesome gem.

I am new in Ethereum.rb and I am trying to load a simple smart contract in my Ruby on Rails application.

I am using:

After setting up the system, creating a new client that connects to Parity and creating a new wallet I proceed to create a new contract and deploy it:

def self.deploy_carepoints_contract
    contract = Ethereum::Contract.create(client: client, file: "#{Dir.pwd}/app/contracts/CarePointsToken.sol").new
    key = Eth::Key.decrypt File.read("#{Dir.pwd}/parity/key.json", "Lberdo1991")
    contract.key = key
    address = contract.deploy_and_wait()
  end

def self.client
    Ethereum::HttpClient.new("http://parity:30303")
  end

However the function fails in the line:

    contract = Ethereum::Contract.create(client: client, file: "#{Dir.pwd}/app/contracts/CarePointsToken.sol").new

The error message is:

EOFError (end of file reached)

I checked the path to the file is correct and the file can be readed. Do you know what might be the issue?

I just discovered the problem was related to the parity server. Using kauriorg/parity-docker image and connecting to port 8545 everything works fine.
