state variable value not changing

Question

I have very simple solidity code as below -

pragma solidity ^0.5.6;

contract SaveData {
  uint public salary;

  function setSalary(uint input) public {
        salary=input;
  }

  function getSalary() public view returns(uint) {
        return salary;
  }

}

I am calling savedata.setSalary(5000) from eth console. It generates a transaction. However after mining the transaction when I ran savedata.getSalary() it always return me 0. I tried allocating a lot of GAS as well.

Answer 1

Try following commands after migration. I am using truffle console.

• SaveData.deployed().then((instance) => instance.setSalary(1000))

• SaveData.deployed().then((instance) => instance.getSalary())

and its working for me.
