Manipulating json: changing the form of visualization

The latest is not valid json.

It’s just an Enum.map with an anonymous function taking a map as input, and returning a tuple.

When I run this

cols = [
  %{id: "12321", name: "Name1"},
  %{id: "231412", name: "Name2"},
  %{id: "2131245", name: "Name3"}
]

cols |> List.to_tuple

the result and that

{
%{id: "12321", name: "Name1"}, 
%{id: "231412", name: "Name2"},
 %{id: "2131245", name: "Name3"}
}

Basically now, I just needed to remove these “id:”, “name:”

How can I do this?

Some hint

& {&1.id, &1.name}

I asked the question because I wanted this function to work.

Enum.map(cols, fn {col,_} -> {col,"true"} end) |> Enum.into(%{})

But this is impossible, because You iterate over maps, not tuples.

That’s the problem.
Would you have any suggestions for this to work?
Remembering that the cols result cannot change.

I thought I gave You the solution already.

Sorry, I didn’t notice.
Enum.map (cols, fn% {id: id, name: name} -> {id, name} end)

Thank you

If you want a map as the end result, I’d recommend Map.new/2

Map.new(cols, fn %{id: id, name: name} -> {id, name} end)

Any code of the form Enum.map(input, some_fun) |> Enum.into(%{}) can be expressed as Map.new(input, some_fun)
