How to filter below enumerable which has value more than one ?
[
{"12130", [%{id: 1410, val: "12130"}, %{id: 1414, val: "12130"}]},
{"65130", [%{id: 1385, val: "65130"}]},
{"65180", [%{id: 1386, val: "65180"}]}
]
On the example above 12130 should be the one that filtered

Hey Yudy, what have you tried so far?
yudy
@benwilson512
I am getting that enum from group_by of ecto result as below
result |> Enum.group_by(fn x → x.val end )
I have tried to chain that group_by result like below
|> Enum.filter(fn {x, y} -> Enum.count(y) > 1 end)or below code|> Enum.filter(fn %{x: y} -> Enum.count(y) > 1 end)or below code|> Enum.filter(fn x, y -> Enum.count(y) > 1 end)or below code|> Enum.filter(fn x, [y] -> Enum.count(y) > 1 end)etc … which combine {}, , %.
Basically I don’t know what data type this is called, that is why I am having difficulty to use correct formula.

What you are looking at is a list of tuples, so you can do it this way:
