Delete button issue

[ArielPenna]

the delete button does not automatically update the render, I have to reload, and in the single post page i doesn't redirec me to home either.
Any Idea?

[ArielPenna]

the console.log brings the getposts aray perfectly, but the console throw a "can't read property getPosts of undefined"
error

Hello @ArielPenna , this might solve your issue:

You should add a poll interval to your useQuery in your Homepage.js, like this:

const {loading, data={}} = useQuery(FETCH_POSTS_QUERY,{
    pollInterval: 500,
  });

Hi, @mariusflorescu thats not working either

[mariusflorescu]

Agh sorry, I didn't read the issue carefully enough.
Try to apply the previous changes + the pollInterval
See the edit.

@mariusflorescu thanks, but it didn't solve py issue, the problem is tha when i press de delete button, it actually delet the post but no reload (when in home) or redirect to home (when in singlepost)

I had the same issue and fixed it using proxy.modify.

      proxy.modify({
        fields: {
          getPosts( existingPostRefs, { readField }) {
            return existingPostRefs.filter( postRef => postId !== readField("id", postRef ));
          }
        }
      })

Instead of modifying data.getPosts and passing it into proxy.writeQuery, just set a data element directly:

proxy.writeQuery({
  query: FETCH_POSTS_QUERY,
  data: { getPosts: data.getPosts.filter((p) => p.id !== postId) },
})
