Update Cell after mutation

nexneo · June 1, 2020, 2:06pm

Hello,

I’m new to Apollo, mostly I have used Redux so far.

I have Entity form in cell A and Entity list in cell B. Once I update Entity, how I can force cell B to re-fetch data so list can be updated.
I have found Reading and writing data to the cache - Apollo GraphQL Docs but kind of lost.

Thanks for any help!

Thanks, I had tried that first before asking. It kind of works but it keeps refreshing always. I only want to fetch fresh data only when update is made. i.e after mutation

redwoodjs/example-todo/blob/master/web/src/components/AddTodo/AddTodo.js#L23


      status
    }
  }
`
const AddTodo = () => {
  const [createTodo] = useMutation(CREATE_TODO, {
    // An example of updating Apollo's cache. This will trigger a re-rended of any
    // affected components, so we don't need to do anything but update the cache.
    update: (cache, { data: { createTodo } }) => {
      const { todos } = cache.readQuery({ query: TODOS })
      cache.writeQuery({
        query: TODOS,
        data: { todos: todos.concat([createTodo]) },
      })
    },
  })

  const submitTodo = (body) => {
    // An example of providing an optimistic response to a GraphQL mutation. Note
    // that `__typename` is required for each object in order to make this work.
    createTodo({
