Reusable Ash Resources

I’m curious, why do we have to put otp_app on the resource?

I’d have to ask Rebecca since she fought with the archival stuff for a while on my app. Pretty sure your only need to do the archival block base filter. I’ll check with her when she some online and post the answer here.

Sometimes it is helpful to break them apart, but for my use case I didn't

But, it all depends on how you want to model your domain. If you want to have a Foo resource and an ArchivedFoo resource pointing to the same table with different base filters, that works too

I forgot why I have base_filter_sql in the postgres block and base_filter in the resource block. Did it awhile back, but seems to work ok.

The archive block specifies which actions are excluded from the base filter.

The base filter means the default read will always filter out archived records

You shouldn't have to create a separate resource for the archived items.

postgres do
  table "foos"
  repo MyApp.Repo
  base_filter_sql "(archived_at IS NULL)"
end

archive do
  exclude_read_actions [:read_archived, :read_all]
  base_filter? true
end

resource do
  base_filter expr(is_nil(archived_at))
end

actions do
  defaults [:read, :update, :create, :destroy]

  read :read_all

  read :read_archived do
    filter expr(not is_nil(archived_at))
  end

  update :unarchive do
    change set_attribute(:archived_at, nil)
    atomic_upgrade_with :read_archived
  end
end

postgres do
  table "foos"
  repo MyApp.Repo
  base_filter_sql "(archived_at IS NULL)"
end

archive do
  exclude_read_actions [:read_archived, :read_all]
  base_filter? true
end

resource do
  base_filter expr(is_nil(archived_at))
end

actions do
  defaults [:read, :update, :create, :destroy]

  read :read_all

  read :read_archived do
    filter expr(not is_nil(archived_at))
  end

  update :unarchive do
    change set_attribute(:archived_at, nil)
    atomic_upgrade_with :read_archived
  end
end

Then set up your policies to allow some user groups to read_archived, read_all, and unarchive.

You’ll need to add ‘batch_change/3’ callback and apply the change function to all changesets.

Complex Custom Actions

As for the Ash.Changeset.new vs Ash.Changeset.for_update, the typical pattern is to use for_update and the name of the update action you are applying.

Complex Custom Actions

For the last question, you're looking for run and a change module. Using the manual opt says you are delgating to your own Update action implementation, so no other changes are applied. While run takes an anon function or change module to run a change on the changeset, so other changes steps can be applied when using run

Try setting store_resource_identifier?: true to see if it adds a column to the table and stores the resource's short_name. Also, we should probably move this conversation to https://discord.com/channels/711271361523351632/1253438465543245844

It looks like paper_trail provides the opts necessary to have a single Version resource that stores entries from multiple resources. If this is incorrect, feel free to correct me.

Use ES Lint, Jest, Prettier configs with deno

Awesome. Deno looks great. You guys have done a phenomenal job. I’m looking forward to the extensibility. Thanks for the help and information.

Thanks for the responses and guidance. I had noticed the deno fmt --unstable-component flag and thought it could be extended. But, after reviewing the demo fmt code, I see it's simply looking at the file extensions for those frameworks and calling format_html since those frameworks name their HTML templates with custom extensions. LWC doesn't do this; it only has .html and js/ts files. So, the formatter should work for LWC. However, for linting, LWC has many ES Lint rules for various functionalities that the framework provides. Is there currently a way to add your own rules to deno lint? If not, are there any plans for this in the future?

Is there a way to extend for a framework? I saw there were some unstable support for Vue and Svelte
