Why does .deployed() in truffle with testrpc return first address?

Question

I created a simple contract and deployed in with testrpc using truffle migrate. In the contract I have a variable

creator = msg.sender;

When calling the contract, it shows that the contract is always called on the first address from the 10 addresses in testrpc.

This is how i call the contract in the truffle console:

var instanceTest MyContract.deployed().then(function(instance) { instanceTest = instance; }) instanceTest.creator.call()

This returns the first address from the list of addresses in the chain. Why is it the first and how do I call the contract on another address?

Thank you.

Answer 1

Truffle uses the first the default address so msg.sender would be accounts[0]

To change it use this:

var creatorAddress = accounts[0];
var firstOwnerAddress = accounts[1];
var secondOwnerAddress = accounts[2];
var externalAddress = accounts[3];

So know you have these address that you can use in your code:

To call a function from these addresses just use this:

 var instanceTest
 MyContract.deployed().then(function(instance) { instanceTest = instance; })
 instanceTest.creator.call({from: firstOwnerAddress})

Notice I used from within the curly braces in the call parameter.
