Mix ash.gen.resource failing on new project

I first create a new ash project as follows:

#!/bin/bash
if [ -f .env ]; then
    export $(grep -v '^#' .env | xargs)
fi
# Enable command echo
set -x

mix archive.install hex phx_new

# add deps
packages=(
  "ash@github:ash-project/ash"
  "ash_postgres@github:ash-project/ash_postgres"
  "ash_phoenix@github:ash-project/ash_phoenix"
)

mix igniter.new $PROJECT_NAME \
  --install $(IFS=,; echo "${packages[*]}") \
  --with phx.new \
  --extend postgres \

I then create a resource as follows:

if [ -f .env ]; then
    export $(grep -v '^#' .env | xargs)
fi
#PROJECT_NAME_CAPITALIZED
PCN=\
$(echo "$PROJECT_NAME" | awk '{print toupper(substr($0,1,1)) substr($0,2)}')

# Enable command echoing
set -x

cd $PROJECT_NAME
mix ash.gen.resource $PCN.Support.Ticket \
    --default-actions read \
    --uuid-primary-key id \
    --attribute subject:string:required:public \
    --extend postgres

This leads to the following error:

% mix ash.gen.resource Helpdesk.Support.Ticket \
    --default-actions read \
    --uuid-primary-key id \
    --attribute subject:string:required:public \
    --extend postgres

If I’m not wrong, this setup was working until a few commits ago. Was working before Jul 24th if memory serves right.

Thank you for the report! Fixed in 3.3.1

Not sure if this is related to the latest fix, but I’m throwing a lot of errors now when running the mix ash.setup command following along on the guide to manually add postgres as a data layer. I just updated the dependency to 3.3.1 to resolve this original error which I was experiencing as well.

 mix ash.setup
Getting extensions in current project...

......

However, the setup and migrations appear to run correctly.

:thinking: that is quite strange. I don’t think I’ve ever seen anything like that before
'Elixir.Mix.Tasks.Reactor.Install 2' is definitely not a module name we’d ever create.

Strange.

In case anyone else sees this error, I ran:

mix deps.clean --all
mix deps.get
mix deps.compile

and was able to finally run mix ash.setup without the long list of errors.

getting an error with --extend now:

mix ash.gen.resource $PCN.Support.Ticket \
  --default-actions read,create,update,destroy \
  --uuid-primary-key id \
  --attribute subject:string:required:public \
  --relationship belongs_to:representative:$PCN.Support.Representative \
  --timestamps \
  --extend postgres,graphql

** (Mix) Could not invoke task “ash.gen.resource”: 1 error found!
–extend : Missing argument of type keep

works when --extend is omitted

If I then try to do an extend on this resource after creation I get the following error:

albin@Albins-MacBook-Pro helpdesk % mix ash.patch.extend Helpdesk.Support.Ticket postgres
Issues during code generation
* Could not find module to extend: Elixir.Helpdesk.Support.Ticket

N.B. This is a fresh project so Support.Representative does not exist yet

:thinking: please open an issue on ash I will look into it this week.
