schema.pre('validate'), override `this`

[Vadorequest Mini Vado]

Hi. I'm trying to use the middleware to add a default value, based on another document, in the pre validate event (not pre save because without this element the validation will fail).

I tried to do so, following the official mongoose documentation, but so far I failed.

I created a stackoverflow question about it but nothing useful yet so I'm asking here, hoping to be pointed out on the good direction.

Thanks.

It looks like you are not quite using parallel middleware correctly as well as not keeping a reference to the correct `this` in the outer scope of your query callback.
