Hey Elixir-Lang-Talk!
I have a question about dealing with complicated API requests in a
functional way. If we are given a JSON response that looks something like
this:
{
“room_id1”: {
“date1”: {
“id”: "3",
“other_variables”: 1,
“other_variables”: 2,
“important_stuff”: {
“id”: “2342”,
“child_id1”: {
“var1”: 1,
“var2”: 1,
“var3”: true,
},
“child_id2”: {
“var1”: 2,
“var2”: 2,
“var3”: true,
},…
}
}
and we want to take information held in the keys and place it in the inner
most object (i’ve called it important stuff). Such that the final data
looks like this:
[{
room_id: “room_id1”,
date: “date1”,
child_id: “child_id1”,
var1: 1,
var2: 1,
var3: true
},
{
room_id: “room_id2”,
date: “date2”,
child_id: “child_id2”,
var1: 2,
var2: 2,
var3: true
}]
How might we manage this in a functional way, without side effects? At the
moment, I have triple nested Enums, building the object which is then
inserted directly into a database via Ecto. I would really like to separate
the transforming of the API data with the inserting of that data in the
database.
Thanks,
Sam
