Support population one level deep

[ekryski]

It's pretty reasonable, especially when using population inside of the server, to allow populating (ie. joining) directly related tables.

Let's take an example of getting all the blog posts for a user but you also want the comments.

When a GET request is sent to /posts, the unencoded query string syntax should probably be:

{
  userId: 1,
  $populate: ['comments']
}

Which would result in a find on the posts table with a join on comments where posts.id = comments.postId.

Soliciting feedback, as you can also accomplish this with hooks, so maybe it should be left up to the user to implement.

I think we can do this now with the populate hook so I'm going to close this.

Yeah you can. I was going to write my own using mongooses populate function but all I ended up having to do was:

userService.after(hooks.populate('posts', {
    service: '/posts'
}))

Works like a charm.
