How to use writeFragment?

[cevr]

Im using writeFragment to update a row in a list I'm displaying. The fragment reads correctly, but it doesn't seem to be propagating the update when I try to write.

The event is never updated. Am I missing something?

Have you tried adding cases to your fragment, else it won't be able to write 😅 it uses the fields in your fragment to know what you want it to write.

So:

  cache.writeFragment(
    gql`
      fragment _ on CaseManagementEvent {
        id
        cases { id status __typename }
      }
    `,
    {
      id: variables.eventId,
      cases: [{ ...result.createCaseFromEvent, __typeneame: 'Case' }]
    },
  );

Oh really? https://formidable.com/open-source/urql/docs/api/graphcache/#writefragment says that I didnt have to haha

Hmm, let me double check, I think this is just for the key-creation but if so that should be clarified

Adding the __typename to the fragment ended up working 😅 but it didnt propagate the change to the row

If you have a reproduction I'd be open to having a look, checked our testing suite and everything seems ok. Example https://github.com/FormidableLabs/urql/blob/main/exchanges/graphcache/src/store/store.test.ts#L508
