How do i see my records stored in the ethereum blockchain

Question

So I have a smart contract, in my code, I have an array and i am pushing to it using a particular method call addToUser, from the code below Contract Example{ string[] users; function addToUser(_user) public { users.push(_user); } } from my understanding when I call the addToUser method above and I push records to it. users is stored in the contract storage(which I am thinking of, as a database). my confusion is, how do I see all the users. like how do I access the database to see all the records and what happens when I redeploy the contract?

Answer 1

1. Declare string[] public users;
2. Add function getNumOfUsers() public view returns (uint256) {return users.length;}
3. In your Truffle test, do something like this inside an async function:

const numOfUsers = await myContract.getNumOfUsers();
for (let i = 0; i < numOfUsers; i++)
    console.log(await myContract.users(i));
