Gov2: list of who is voting on what | Polkadot.js api

Question

I'm building an automation for the Gov2 referenda module, testing right now using wss://governance2-testnet.litentry.io test network with polkadot.js app

Differently from what the democracy module we currently have in Polkadot and Kusama, I cannot retrieve anymore the list of who is currently voting on what. Not even from the api calls. Am I missing something ? or is the new system supposed to not store that information anymore?

Answer 1

With PolkadotJS you can get information about a specific referendum with this code:

const referenda = await api.query.referenda.referendumInfoFor(48);
console.log(`Referenda: ${JSON.stringify(referenda.toHuman())}`);

And you get the total number of ayes and nayes votes, with other information:

    Referenda: {"Ongoing":{"track":"0","origin":{"system":"Root"},"proposal":{"Lookup":{"hash_":"0x4bdd1d956c24c6dc9ce1c07f6c3cc1a82d5db63dc6d895bdd5a035f60ef58006","len":"106"}},"enactment":{"After":"100"},"submitted":"16,019,459","submissionDeposit":{"who":"DrQ3WAwSyMsZpaUvwP11j63QJC2wmGUH3BWPoxj5kqgA3A1","amount":"33,333,333,333"},"decisionDeposit":null,"deciding":null,"tally":{"ayes":"24,025,722,234,946,176","nays":"72,721,623,600,000,000","support":"17,151,464,474,841,370"},"inQueue":false,"alarm":["16,221,059",["16,221,059","0"]]}}

Is this one in Kusama

Also you can get the list of all referendums (Finished and OnGoing):

const allEntries = await api.query.democracy.referendumInfoOf.entries();
    allEntries.forEach(([{ args: [id] }, referendum]) => {
        console.log(`${id}: Referendum: ${JSON.stringify(referendum.toHuman())}`);
 });

But if you want to see who vote in that referendum I suggest you to use the SUBSCAN API, the endpoint /scan/democracy/votes where you can get the voters specifying the referendum ID.

This is what Polkassembly is using to get all the voters. Check their code here.

     fetch(`https://kusama.api.subscan.io/api/scan/democracy/votes`,
            {
                body: JSON.stringify({
                    page: currentPage,
                    referendum_index: referendumId,
                    row: 10
                }),
                headers: subscanApiHeaders,
                method: 'POST'
            }).then(async (res) => {
            const votersData = await res.json();

            if(votersData && votersData.data && votersData.data.list) {
                if(!count) {
                    setCount(votersData.data.count);
                }
                setVotersList(votersData.data.list);
            }

            setLoadingStatus({
                isLoading: false,
                message: 'Loading Data'
            });
        }).catch((err) => {
            console.error('Error in fetching vote data:', err);
        });

Answer 2

We can get the final blocks of each referendum by calling Referenda.ReferendumInfoFor storage function, and then for each referendum and respective final block, make a call to ConvictionVoting.VotingFor and parse all the votes for the referendum in question. For ongoing referenda we just pass the chain head.
