Hello community,

I’m new to phoenix and struggling to implement a feature that would allow my users to apply a theme of their choice (e.g. animals, cars, nature).

Each of these themes has its own assets and I’m using put_layout to assign the chosen layout but struggling to render the views according to the chosen theme

My controller looks like this

defmodule Client.PageController do
  use Client, :controller
  
  def index(conn, _params) do
    theme = get_user_theme(conn)

    conn
    |> put_layout(theme)
    |> render('index.html')
  end
end 

My templates directory

templates\
 -> layouts
     - app.html.eex
     - themeA.html.eex
     - themeB.html.eex
 -> pages
     - index.html.eex
 -> themeA
     - index.html.eex
 -> themeB
     - index.html.eex

how do i dynamically choose between themeA/index.html.eex and themeB/index.html.eex without getting a template not found error
