If inside anonymous function

Questions / Help
1

so i have a code :

whitelisted_params =
  params
  |> Map.take(
    ~w(id ph_id name address)
  )
  |> Enum.map(fn {k, v} -> {String.to_atom(k), String.replace(v, ~r/[^\w\s\-]/, "")} end)

i’m trying to convert String.replace(v, ~r/[^\w\s\-]/, "") to integer if key is id or ph_id

The if/2 would work as everywhere else as well:

fn {k, v} ->
  k = String.to_atom(k)
  v = String.replace(v, ~r/[^\w\s\-]/, "")}

  v = if k in [:id, :ph_id] do
    String.to_integer(v)
  else
    v
  end

  {k, v}
end

For a bit more readability I’d also make the chain longer and use pattern matching, like this:

params
|> Map.take(~w(id ph_id name address))
|> Enum.map(fn {k, v} -> {String.to_atom(k), String.replace(v, ~r/[^\w\s\-]/, "")} end)
|> Enum.map(fn
  {k, v} when k in [:id, :ph_id] ->
    {k, String.to_integer(v)}

  tuple ->
    tuple
end)
