I was trying to set up Ash Admin for a small experiment project.

Request: GET /admin
** (exit) an exception was raised:
    ** (UndefinedFunctionError) function FamWeb.AshAdmin.PageLive.__live__/0 is undefined (module FamWeb.AshAdmin.PageLive is not available)
        FamWeb.AshAdmin.PageLive.__live__()

From the instructions I don’t believe I’ve missed anything at this point. But I’m clearly missing a generated LiveView in some way.

Api file:

defmodule Fam.Api do
  use Ash.Api, extensions: [AshAdmin.Api]

  resources do
    registry Fam.Site.Registry
  end

  admin do
    show? true
  end
end

I have one resource and it all matches the base getting started tutorial aside from some names.

      {:phoenix, "~> 1.7.2"},
      {:phoenix_live_view, "~> 0.18.16", override: true},
      {:ash, "~> 2.15"},
      {:ash_admin, "~> 0.9.4"},
      {:ash_postgres, "~> 1.3"},
      {:ash_phoenix, "~> 1.2"}

Any idea what I’m hitting here?

Found it. I had:

  scope "/", FamWeb do
    pipe_through :browser

    ash_admin "/admin"
  end

instead of

  scope "/" do
    pipe_through :browser

    ash_admin("/admin")
  end

Problem makes sense. Was very confused :smiley:

Thank you that is very helpful,
for all the ones who are a bit blind like me, and need a bit of context
lawik did a seperate scope for “/” because the FamWeb in

Scope "/", FamWeb do

is used as prefix.
thats why lawik has

FamWeb.AshAdmin.PageLive

in the error message.

i got the explanation from a forum post at ash_hq
