JoinAshEvents: AshPostgres.DataLayer.Info.repo/1 is undefined
After installing ash_events on a working Ash+Postgres app (by adding {:ash_events, "~> 0.2.0"}), I get this warning when I start it. Application works otherwise but I don't have ash events wired to any resources yet.

Reusable Ash Resources
I've got a commonly-used Ash resource that I'd like to put in an Elixir package for reuse across Phoenix apps. Is anyone doing this? Can anyone point me towards examples or best practice?
This works, but the

Igniter `Proceed with changes` message when there is no changes
Hi, as you see this is my simple code for igniter, i am using
update_file function, because before it i have a function that ensure_package_json_exists.
I do not know why it shows me even there is not changes Proceed with changes?
It is is my bug?
I tried to use create_or_update_file function, but if file exist and there is not anything to change, it still shows Proceed with changes?
...Solution:
I think the latest version of igniter may have a fix for this?
livebook
Has anyone ever created some Ash resources and tried to use (ie create and interact with) them in a LiveBook without publishing code to Hex or a private repository? I'm in the middle of trying. The concept: use Livebook instead of iex. I know, crazy.
Solution:
The problem with the excellent educational livebook for my case is that I'm not learning Ash -- I want something better than IEx to interact with my code (which depends on Ash and a ton of other functionality), like a library. I am not just asking the universe for a solution. I have a solution for my app, and it's pretty bad. I will document this and I'm closing this issue. Anyone who stumbles on this post should be aware that they should not attempt.
createdby / updatedby
When ash_authentication is in use, do you recommend adding created_by and updated_by references for other resources to the user resource.. or is this a dumb thing to do?
Solution:
It depends entirely on the situation 🤷♂️

Add custom key in a action or other macro without changing the core of Ash
Hi, i am creating a dashboard lib, that support multi ACL, so i want to ask i can add a custom key inside
action without changing Ash core? and access it for my dashboard? it is not just user role access for example another options like where this action should be shown or the icon of it and etc
Or i am forced to create my own macro?! out of action or etc! (this is very dirty way)

Pubsub isolation in tests
I have a Phoenix application which has LiveView tests.

AshOban job failures
I have a job that runs using AshOban, which I find a very nice way of doing things tbh, as most things you've done so far!
However it seems to me that the only way to handle failures is to give it an action to run. For example setting the state to failed, however I'd like to be able to see the failure in Oban apart from setting the Resource as failed. I have scoured the documentation but I don't see a way of having the Oban job fail on failure. Am I missing something? Was there a specific reason this is like this?...

```...Writing a Change with DB lock
I have a
change that do some db queries in order to verify that the value being inserted in a foreign key is valid. Since I'm being based on other records to validate this field I need to lock those to prevent them to be modified in the middle of the change.
Before adding any locking to my change I decided to test this concurrent scenario so first I make it fail so then I could be certain the problem is solved once I lock the records.
My current issue is that the tests mean to run concurrently are not failing. No mater how many times I run the tests, the records are being updated in order as if a locking mechanism were in place...Slow pages ... due to too many load of data...
