@illuday commented on @playra’s file : Nop, if you want to do this automatically you need to make a custom resolver.

js
async writePost(parent, { title, text }, ctx, info) {
    const authorId = getUserId(ctx)
    return ctx.db.mutation.createPost(
      {
        data: {
          title,
          text,
          isPublished: true,
          author: {
            connect: { id: authorId },
          },
        },
      },
      info,
    )
  }

You should try the basic project from the @beta release.
