[question] Accessing 'req' object in a mongoose middleware

Can I somehow add req.user._id to document before saving it.

Something like:

schema.pre('save', function (next) {
  this.createdBy = req.user._id;   // is it possible to access req here?
  next()
})

Do you know if it is possible to achieve something like that?

My highly opiniated view on this is that you should not use req in your models as it couples your database with your web framework so I would recommend using the method I outlined above.

That said, we could investigate passing req into save. However, I’m curious as to what happens in the case of async middleware.

Mongoose middleware doesn’t have access to the request object, it is also a separate project for which you can find documentation in their repository.

What you can do, is use our preCreate middleware.

restify.serve(router, model, {
  preCreate: function (req, res, next) {
    req.body.createdBy = req.user._id
    next()
  }
})
