Can't get all balance of contract

Sway
1

Here is the link to my Money Box smart contract which I am trying to get the total balance of the specified token

https://github.com/sway-gang/money-box/blob/total_balance_of/src/main.sw

 fn total_balance_of(asset_id: ContractId) -> u64 {
        balance_of(contract_id(), asset_id)
    }

But when I run this contract with following test I keep getting 0 as token balance

https://github.com/sway-gang/money-box/blob/total_balance_of/tests/local_tests/main_test.rs

let contracts = [Bech32ContractId::from(contract_id)];
    let total_balance = methods
        .total_balance_of(contract_id)
        .set_contracts(&contracts)
        .simulate()
        .await
        .unwrap();
    println!("total_balance: {}", total_balance.value);

Please help)

Your link doesn’t work for me, is that a public repo?

Thanks! This looks like a type mismatch, as contract_id() returns a ContractId, so the key you provided is of type (ContractId, ContractId) instead of (Address, ContractId). You might want to consider using Identity instead, which can be either an Address or ContractId:

Can you please send a sample code with the problem fixed?

Tried using identity, same result.

 let identity = Identity::ContractId(contract_id);
    let total_balance = methods
        .total_balance_of(identity)
        .set_contracts(&cotarcts)
        .simulate()
        .await
        .unwrap();
    println!("total_balance: {}", total_balance.value);

And the address cannot be used as an argument because of a compilation error

My apologies, the type is not the issue here. It is actually just the order of the arguments passed to the balance_of function. It should be balance_of(asset_id, contract_id()) . You can see the full code for this function here: sway/context.sw at 949dfb98bd8ad0d89c5a59a33b391892e665a760 · FuelLabs/sway · GitHub

It would be better to use this_balance(asset_id) in that case
