@snewcomer this is a good first go, I've left some feedback and questions. I do think we should think about whether we want to be passing conn into the functions, that opens the door for misuse and confusing behavior.
Let's think about it a bit and give @jeregrine a chance to share his thoughts 👍

What does merge/3 offer us over just using Map.put/3 directly?

This was to ensure the return type was a Map, which is what Map.take was doing before.

Can we do something like this to DRY things up a bit?
value =
try do
apply(__MODULE__, field, [data, conn])
rescue
_e -> Map.get(data, field)
end
Map.put(intermediate_map, field, value)

@doomspork Good calls. So the only reason to also pass conn would be to get at the current user or something like that. So if your API is returning a list of users, for every user you could ensure that only the current logged in user's email was sent back. Lmk your thoughts!

Thank you @snewcomer! I want to review #87 and then we can cut a new release 😁 |
