api.derive.democracy.referendumVotes is not a function

[vikiival]

Hello,

I face a problem with fetching votes for selected referendum from api.
According to implementation I need to just call api.derive.democracy.referendumVotes(index)
unfortunately this method doesn't work on api@1.8.1

If I want to use old approach with api.derive.democracy.referendumVotesFor(index)
I got another error:

DRR: TypeError: "api.query.democracy.votersFor is not a function"

Used chain: Kusama CC3

Thanks 🚀

If you want to use the derives for this, you are better suited with the 1.9-beta versions which has full support for the new democracy in all derives.

And yes, as expected with the upgraded democarcy, the old endpoints are not decorated - https://polkadot.js.org/api/start/basics.html#metadata

The API can only make available what is exposed by metadata, after 1055 on Kusama those old query endpoints don't exist.

PS: The apps UI always use the API betas, so it will be different from the release versions. These derives (new in 1.9) will change again significantly during the 1.9-beta series before release, so the beta interfaces are not "final" or anywhere close to it.

@jacogr So what's the smartest approach to solve this using stable api (snippet would be great) ?

[jacogr]

Make the queries directly via api.query.* as per the chain you are connecting to. Each chain exposes the info and exposes queries via metadata, albeit in different places, there is no real magic behind derives.

All derives do is to grab info from multiple sources, supporting all available query types and construct it into a usable format - these undocumented for a reason, since they can change at will, and certainly after massive breaking democracy changes, they are changing very rapidly for the sake of efficiency.
