Daml start

Hello everybody, I tried to run a smart contract that I’ve created on the browser using the command daml start in the terminal. However, when I display the page in the browser, it gives as parties still alice and bob even if I changed them on visual studio code in the contract. Is there a way to change it?

Thanks in advance!

Hi @Alice,

Can you describe in more details what you have done to get at this screen? If you’re running a brand new project resulting from daml new my-project, the list of options for login on that screen will be set by the parties entry in daml.yaml, and will be independent of your Daml code.

Hi @Alice and welcome to the forum!

You can define the party names in the daml.yaml file in order for them to be visible in the Navigator

I managed to change the names in the daml.yaml file as you suggested. However, now when I run the navigator I can’t display any contract under the contract section. Do I have to modify something else to have the correct contract displayed in the navigator?

Also a page called navigator.log opened and it displays some errors.
This is what it displays.

A Daml ledger supports dynamic allocation of parties, so there isn’t a “known, fixed” list. The list of party names you put in your daml.yaml file is the list of parties that will be able to log into the Navigator, but they are by no means the only parties existing on the ledger.

In order for you to view contracts in the Navigator, you need to have contracts on the ledger that are visible to the party your are connecting as with the Navigator.

So if you have connected to the Navigator as “Mario”, you’ll need to have created contracts visible to the Mario party beforehand. You could do that through the execution of a Daml Script. It’s going to be easier to give you more precise directions if you could share your daml.yaml file and your Daml code, but roughly speaking you might have a setup method somewhere that is allocating parties and creating contracts for them. You would need to modify that code to assign some contracts to the Mario party.

I changed the names in the daml.yaml file, but when I open the navigator I can’t display a contract.

Also a file called navigator.log immediately opened displaying errors. This is what it displays:

What I’m wondering is if I have to change the names also in the main.daml file because there it has Alice and Bob. Do you think that this should fix it?
Anyway I’ll show you the daml.yaml and main.daml

daml.yaml
# https://docs.daml.com/tools/assistant.html#project-config-file-daml-yaml

sdk-version: 1.13.1
name: passport-create
source: daml
init-script: Main:setup
parties:
  - Mario
  - Ministry of Foreign Affairs
version: 0.0.1
dependencies:
  - daml-prim
  - daml-stdlib
  - daml-script
sandbox-options:
  - --wall-clock-time

Module main
module Main where

import Daml.Script

type AssetId = ContractId Asset

template Asset
  with
    issuer : Party
    owner  : Party
    name   : Text
  where
    ensure name /= ""
    signatory issuer
    controller owner can
      Give : AssetId
        with
          newOwner : Party
        do
          create this with
            owner = newOwner

setup : Script AssetId
setup = script do
  alice <- allocatePartyWithHint "Alice" (PartyIdHint "Alice")
  bob <- allocatePartyWithHint "Bob" (PartyIdHint "Bob")

  aliceTV <- submit alice do
    createCmd Asset with
      issuer = alice
      owner = alice
      name = "TV"

  bobTV <- submit alice do
    exerciseCmd aliceTV Give with newOwner = bob

  submit bob do
    exerciseCmd bobTV Give with newOwner = alice

Thanks in advance for the help!

Yes, I think changing:

setup = script do
  alice <- allocatePartyWithHint "Alice" (PartyIdHint "Alice")
  bob <- allocatePartyWithHint "Bob" (PartyIdHint "Bob")

to:

setup = script do
  alice <- allocatePartyWithHint "Alice" (PartyIdHint "Alice")
  bob <- allocatePartyWithHint "Bob" (PartyIdHint "Bob")

  mario <- allocatePartyWithHint "Mario" (PartyIdHint "Mario")
  ministry <- allocatePartyWithHint "Ministry of Foreign Affairs" (PartyIdHint "Ministry of Foreign Affairs")

might get rid of that error. Unless you also change the code further down, though, this would not actually create any contract for them so you’d still see an empty set of contracts in Navigator.

I tried doing what you’ve written here, but the errors on navigator.log are still there and as you said it didn’t create a contract in the navigator. Do you have any further suggestion?

Hi @Alice,

I am unable to reproduce the errors you’re seeing. With the exact same daml.yaml and daml/Main.daml fiels as you, when I run daml start I get a working Navigator. There are no errors printed in navigator.log and, while there are no contracts prepopulated (since the setup script creates contracts for unrelated parties), I can use Navigator to create a contract with Bob and give it to Ministry of Foreign Affairs, at which point they both see one contract (the on I just created).

Can you walk me through exactly how you started Navigator to get these error messages?

I’d also recommend to upgrade to the latest SDK release 1.18.0. Looking at your daml.yaml you seem to still be using 1.13.1.

Ok, I’ll try to install the latest version of Daml.

Just to clarify, I was not able to reproduce the error even on 1.13.1, so while I agree upgrading is good, I don’t think it is related.

Hi @Alice :wave:

Were you able to solve the issue?

I ran into the same issue, I solve it by moving the Main.daml into the daml folder and it worked.
