How to validate an event starting from JSON?

[MegalithicBTC]

Thanks for this awesome library!

I've got a question about validating an event.

I've got an event that I'm not receiving from a subscription. I've just got it as JSON.

Here is the event as JSON:

{
  "kind": 9734,
  "content": "asdfasdfasdfsdf",
  "created_at": 1734809820,
  "tags": [
    [
      "relays",
      "wss://nostr-01.yakihonne.com",
      "wss://nostr-02.yakihonne.com",
      "wss://relay.damus.io",
      "wss://relay.nostr.band",
      "wss://nostr.land/",
      "wss://nostr.wine/",
      "wss://nos.lol/",
      "wss://nostr.fmt.wiz.biz/",
      "wss://nostr.mom/",
      "wss://relay.nostr.bg/",
      "wss://relay.noswhere.com/",
      "wss://nostr.oxtr.dev/",
      "wss://nostr.bitcoiner.social/",
      "wss://relay-nwc.rizful.com/v1/"
    ],
    [
      "amount",
      "1000"
    ],
    [
      "lnurl",
      "lnurl1dp68gurn8ghj7etcvd5xzmn8v5hxzur90fjx2a3wvdhk6tewwajkcmpdddhx7amw9akxuatjd3cz7cnvda3kk6r0w4hxgvgav32te"
    ],
    [
      "p",
      "c81e1dc8f582448f63953d7c2b76857981b82fb09123bdab4dec8ff81fb7ceca"
    ],
    [
      "e",
      "4f021c8a4b2ac9889bfa4108c35ea9549e7bc6742354b56b19c40d538e5847dd"
    ]
  ],
  "pubkey": "97f848adcc4c6276685fe48426de5614887c8a51ada0468cec71fba938272911",
  "id": "8df63ede369fff3c5391685e90a22cab838b022af4d72dd41c465000d01596d7",
  "sig": "3da4c99d169310383c9c9e0f7aaec6283b7b72d7af86d0b8d0291cd61b2fffe2e2b900887419f0b4c4509deb58cfd8859cb216858a1abcd12ab03400da833161"
}

I started at this point in your documentation:

https://www.nostr-ruby.com/common-use-cases/signing-and-verifying-events.html#verifying-an-event-s-signature

I can see we're supposed to this

event.verify_signature # => true

But how would we construct the event from the JSON?

Also this code I don't understand

other_public_key = Nostr::PublicKey.new('10be96d345ed58d923a734560680f1adfd2b1006c28ac93b8e1b032a9a32c6e9')
event.verify_signature # => false

The other_public_key variable is never used here.

thanks!

seems like ..

event = Nostr::Event.new(
      id: parsed_nostr_data['id'],
      pubkey: parsed_nostr_data['pubkey'],
      created_at: parsed_nostr_data['created_at'],
      kind: parsed_nostr_data['kind'],
      tags: parsed_nostr_data['tags'],
      content: parsed_nostr_data['content'],
      sig: parsed_nostr_data['sig']
    )
is_event_valid = event.verify_signature

works well.
