Adding a struct to mapping not working on ganache, but works in unit tests?

Question

I have this code

struct User {
    string name;
    string state;
    uint age;
    string[] recommendations;
    address[] following;
}

mapping(address => User) public users;
mapping(address => bool) userExists;

...

function setup(string memory _name, uint _age, string memory _state) public {
    bytes memory nameBytes = bytes(_name);
    require(nameBytes.length > 0, "Name is empty.");
    users[msg.sender] = User(_name, _state, _age, users[msg.sender].recommendations, users[msg.sender].following);
    userExists[msg.sender] = true;
}
function hasAccount() public view returns (bool) {
    return userExists[msg.sender];
}

Which should just add a user to the users mapping and add true to the userExists mapping. This is reflected just fine in the unit test:

contract("Social Music", async accounts => {
const [initialAddress] = accounts;

let instance;

beforeEach(async () => {
    instance = await SocialMusic.deployed();
});

it('should set userExists after setup', async () => {
    await instance.setup('testname', 25, 'Test descr');

    const result = await instance.hasAccount();

    expect(result).to.be.true;
});
});

Which seems to be fine, but when I run the function setup in the browser, which shows up in ganache with correct params, nothing seems to be happening to the mapping afterwards.

Ganache: (FYI these are random strings)

and

Yet when calling hasAccount in the browser or looked at it in the ganache GUI it both seems like its not being added (browser gets false back when doing const hasAcc = await socialMusicInstance.methods.hasAccount().call();). I have no clue whatsoever what this can be about

Answer 1

So it seems that in the function hasAccount I am accessing msg.sender. It seems like this is not working in a view function, so it always returned false.
