How to obtain %{key: value} with list with nested map
My list looks like this
[ %{
"handle" => "a",
"p" => [
%{
"price" => "$10.00",
}
],
"scheme" => "unit",
},
%{
"handle" => "b",
"p" => [
%{
"price" => "$14.95",
}
],
"scheme" => "unit",
},
%{
"handle" => "c",
"p" => [
%{
"price" => "$22.95",
}
],
"scheme" => "unit",
}
]
How can I iterate through the list and get result as below??
[
%{handle: "a",price: "$10.00"},
%{handle: "b", price: "$14.95"},
%{handle: "c", price: "$22.95"},
]

list
|> Enum.flat_map(fn %{"handle" => handle, "p" => prices} ->
Enum.map(prices, &%{handle: handle, price: &1["price"]})
end)

Alternatively you can use a for expression:
for %{"handle" => handle, "p" => prices} <- list,
%{"price" => price} <- prices do
%{handle: handle, price: price}
end
