Can't use mongoose plugin based on pre with patch or put

I’m using this plugin for generating an slug https://github.com/mindblaze/mongoose-url-slugs (I also tried 10 different plugins with the same result)

I have this when I do a “get” to http://localhost:3030/posts/58e77fb2bdce58efa796f183

{
	"_id": "58e77fb2bdce58efa796f183",
	"description": "A description for the First Post",
	"title": "First Post",
	"createdAt": "2017-04-07T12:01:54.976Z",
	"slug": "first-post"
}

If I do a “put” (update in hooks) to the same url with this fields:

{
	"title": "new title",
	"description" : "new description"
}

I get this response:

{
	"_id": "58e77fb2bdce58efa796f183",
	"title": "new title",
	"description": "new description"
}

“createdAt” and “slug” disappeared, of course with “patch” this doesn’t happens but then I can’t generate my slug. 😕

How I can solve this? Should be good to force an update to patch? This can be possible?

I think the problem is that path is not calling the mongoose event ‘validate’

I created a plugin that works with mongoose and feathers that solves this issue

I have the exact same problem, see https://github.com/feathersjs-ecosystem/feathers-mongoose/issues/395
