Could not load MyAshPhoenixApp.Blog, error: :nofile

zac

I’m new to Ash and going through tutorials. In the AshPhoenix walkthrough, after the basic setup I’m getting the following error trying to create the database:

z@Serenity my_ash_phoenix_app % mix ash_postgres.create
** (Mix) Could not load MyAshPhoenixApp.Blog, error: :nofile.

There’s no other info to go on. The referenced walkthrough is: Get Started with Ash and Phoenix — ash_phoenix v2.3.23

Wondering if anyone has run into this error and knows what could cause it? I’ve checked the obvious. MyAskPhoenixApp.Blog is declared in my_ash_phoenix_app/blog/blog.ex:

defmodule MyAshPhoenixApp.Blog do
  use Ash.Api

  resources do
    registry MyAshPhoenixApp.Blog.Registry
  end
end

Confirmed that the right deps are included, etc… any help would be appreciated.

Using Elixir 1.15.7 / OTP 26, and these deps:

      {:ash, "~> 2.16.1"},
      {:ash_postgres, "~> 1.3.6"},
      {:ash_phoenix, "~> 1.1"}

Hi @zac

Sorry for the slow reply.

Can you show me the contents of your config/config.exs?

You bet! Hoping there are no embarrassing typos. It’s the generated config, plus the two lines at the top from the AshPhoenix walkthrough docs. Here you go:

# This file is responsible for configuring your application
# and its dependencies with the aid of the Config module.
#
# This configuration file is loaded before any dependency and
# is restricted to this project.

# General application configuration
import Config

config :my_ash_phoenix_app,
  ash_apis: [MyAshPhoenixApp.Blog]

Huh. Seems fine. This may seem like an oddball question but what is the file path of the MyAshPhoenixApp.Blog module?

No spaces or any other weirdness…

zac@Serenity blog % pwd
/Users/zac/Projects/Elixir/ash/my_ash_phoenix_app/blog
zac@Serenity blog % ls
./           ../          blog.ex      registry.ex  resources/
zac@Serenity blog % cat blog.ex
defmodule MyAshPhoenixApp.Blog do
  use Ash.Api

  resources do
    registry MyAshPhoenixApp.Blog.Registry
  end
end
