PUT (update) does not run mongoose validators

Hi,

I created a really simple model, called tag, with only one property, text, which is required.

text: {
    type: String,
    required: true,
    unique: true,
}

When I POST a new tag, text is required, and I got an error if text is not set.

However, if a do a PUT request on /tags/:idOfTheNewTag with an empty body, my tag is replaced, with a new one with no text. So, that PUT request did not thow an error for the “required” validator.

I have the same issue. It does not validate on patch, too

EDIT: Ahh found the issue. From http://mongoosejs.com/docs/validation.html#update-validator-paths

When using update validators, required validators only fail when you try to explicitly $unset the key.

Going to close this since it is pretty old and this seems to be a Mongoose restriction which can be circumenvented by the aforementioned validate hook or the validateSchema common hook.
