Post model works fine. Is that need to set something?

hexo.extend.processor.register("_posts/:slug\.md", () => {
  const Post = ctx.model('Post');
  const test = Post.findById("Test");
  if (!test) {
    return Post.save({
      _id: "cmdpuk53y0000n4ywg8ki54j7",
      path: "Test",
      slug: "Test",
      source: "123",
      modified: true
    });
  }
});

hexo/lib/plugins/generator/asset.ts

Lines 22 to 23 in c69553c

	return Promise.filter(ctx.model(name).toArray(), (asset: Document<AssetSchema>) => exists(asset.source).tap(exist => {
	if (!exist) return asset.remove();

If asset.source (join(base_dir, _id)) does not exist, it will be removed.

So how can I create outside assets. The marked render need to check assets to generate relation url. Maybe we need a visual file system to manage assets.
