Proposal: adding reverse-relationship population to Mongoose (as implemented in KeystoneJS)

I've developed a useful feature in KeystoneJS that lets you populate a relationship from either side, while only storing the data on one side, and am looking for feedback on whether it is something that could / should be brought back into mongoose itself. (It might be possible to add as a separate package but I suspect there'd be too much rewriting of mongoose internals for that to be a good idea).

I've added this as an issue in mongoose for consideration: #1888 but am leaving this gist in place because the examples are easier to read.

I've used Posts and Categories as a basic, contrived example to demonstrate what I'm talking about here; in reality you'd rarely load all the posts for a category but there are other real world cases where it's less unreasonable you'd want to do this, and Posts + Categories is an easy way to demo it.

The problem

The built-in population feature is really useful; not just for

Facebook Perl source code from 2005. When browsing around thefacebook.com in 2005 the server spit out some server-side source code rather than running it. I believe this was for their old graph feature that let you visualize the graph between all your friends. The filename is `mygraph.svgz` and contains some gems such as a commented out "zuck" d…

It's a résumé, as a readable and compilable C source file. Since Hacker News got here, this has been updated to be most of my actual résumé. This isn't a serious document, just a concept to annoy people who talk about recruiting and the formats they accept résumés in. It's also relatively representative of my coding style.

Since this is on Hacker News and reddit...

  • No, I don't distribute my résumé like this. A friend of mine made a joke about me being the kind of person who would do this, so I did (the link on that page was added later). My actual résumé is a good bit crazier.
  • I apologize for the use of _t in my types. I spend a lot of time at a level where I can do that; "reserved for system libraries? I am the system libraries".
  • Since people kept complaining, I've fixed the assignments of string literals to non-const char *s.
  • My use of type * name, however, is entirely intentional.
  • If you're using an older compiler, you might have trouble with the anonymous unions and the designated initializers - I think gcc 4.4 requires some extra braces to get them working together. Anything reasonably recent should work fine. Clang and gcc (newer than 4.4, at le
