And I think we need to migrate our has-one into this has-many list of per-child item requests.

@elasticspoon unfortunately in prod data there are children with a `item_needed_diaperid` set but no corresponding `Item` record. I'm not sure what caused those.

er -- and the release is blocked until we fix or revert, FYI

Also there are only like 7 children records affected now that I dug in a bit, so likely outcome after an investigation is skipping those. ``` diaper_dev=# select count(distinct(children.id)) from...

@sunsheeppoplar one idea is to go ahead with the fields you have so far, and then we can do a separate PR for anything remaining. It's totally cool to fix...

Right, for clarity -- the system specs don't work _in docker locally_. This shouldn't affect anything outside of local-docker-usage. (above fails are likely flaky specs :( )

I created an issue to tie together this work and a few others, #3829

@dorner I use docker all the time, and some of this was based on the local files I have that aren't committed. This PR hasn't been updated since the switch...

I'd like to hold off on this refactor until after / separate from the dashboard update.

@calopter I think that we should at the very least have `$_` set. In irb/pry they define a lexical `_` to do this, so pretty similar.
