Hi!

I have a couple of structs and I want to build one of them depending on some STRING as input:

defmodule Mystruct1 do ... end
defmodule Mystruct2 do ... end
...
defmodule Mystructn do ... end

def get_struct(name) do
    name
    |> <transformations_here>
    |> struct()
end

the_struct = get_struct("Mystruct5")

Naively I’m trying something like

name |> String.capitalize |> String.to_atom |> struct

but I’m getting this error

** (UndefinedFunctionError) function :Mystruct5.__struct__/0 is undefined (module :Mystruct5 is not available)
    :Mystruct5.__struct__()
    (elixir) lib/kernel.ex:2161: Kernel.struct/3

Besides whether this can be done or not, is this a good idea in order to allow the app to scale by merely adding new structs instead of use pattern matching for every possible input?

Thanks
