eth/contract greeter.sol - "Hash (NoMethodError) Did you mean? min" error #113

Hi All. Thank you very much for this eth gem.

Having trouble with my first ethgreeter test contract. Here is the module, ruby console and run-time error.

What am I missing? Must be something simple but I have read the docs over-and-over; banging head :)

module EthGem 
    require "eth"

    CHAINSTACK_ENDPOINT_ROPSTEN=ENV['CHAINSTACK_ENDPOINT_ROPSTEN'] unless const_defined?(:CHAINSTACK_ENDPOINT_ROPSTEN)
    METAMASK_ETH_ADDRESS=ENV['METAMASK_ETH_ADDRESS'] unless const_defined?(:METAMASK_ETH_ADDRESS)
    DEBUG = false unless const_defined?(:DEBUG)

    class Core
       def initialize
       end

       def self.greeter 
        chain = Eth::Client.create CHAINSTACK_ENDPOINT_ROPSTEN
        puts "METAMASK_ETH_ADDRESS: #{METAMASK_ETH_ADDRESS}"
        deposit_contract = Eth::Address.new METAMASK_ETH_ADDRESS
        balance = (chain.get_balance deposit_contract).to_f
        puts "Balance is #{balance.round(8)}"
        solc = Eth::Solidity.new
        contract = solc.compile "#{Rails.root}/greeter.sol"
        chain.deploy_and_wait(contract)
       end
    end
end

and the error:

Thanks for helping me out.

My "guess" is there is a bug related to this line? Looks like the contract hash is formatted differently than the line below expects?

contract['Greeter']['bin'] versus. contract.bin ?

Or it is some other problem?

Did you mean?  min
q9f commented 2 years ago

I'm sorry, there is some documentation missing. What you need is an Eth::Contract:

chain = Eth::Client.create CHAINSTACK_ENDPOINT_ROPSTEN
puts "METAMASK_ETH_ADDRESS: #{METAMASK_ETH_ADDRESS}"
deposit_contract = Eth::Address.new METAMASK_ETH_ADDRESS
balance = (chain.get_balance deposit_contract).to_f
puts "Balance is #{balance.round(8)}"

contract = Eth::Contract.from_file(file: "#{Rails.root}/greeter.sol")
address = chain.deploy_and_wait(contract)

Let me know if you have any further questions!
