to_atom

[note89]

in database.ex
for {key, val} <- doc, into: %{}, do: {String.to_atom(key), val}

https://elixir-lang.slack.com/team/hamiltop explained that this was not a very good idea in elixir and could lead to a malicious attacker crashing ones servers.
instead to_existing_atom should be used

@note89 I agree but in this case wouldn't it be possible that those keys were never defined beforehand, making it crash because they're not existing yet? (example being that the DB data doesn't match the schema exactly) Or perhaps they would from the schema definition?

I think the bigger issue is that it's needed in the first place to go from String -> Symbol -> String for the response.
