Is a benefit of using Ash primitives like preparations and calculations rather than modify_query that it will be simpler to integrate with other ash functionality like pagination?

I'm getting error: undefined variable "listing", reading the prepare docs. Haven't used this part of Ash yet!

(I'm not sure if this is optimal or the pros/cons vs a calculate-based approach)

st_distance vs <-> in ash_geo for nearest neighbor search/filter (knn)

I have my system working! The action:

read :nearest do
  argument :location, :geo_any do
    allow_nil? false
    constraints geo_types: :point, force_srid: 4326
  end

  modify_query {Panacea.Lociary.ManualNearest, :modify, []}
end

read :nearest do
  argument :location, :geo_any do
    allow_nil? false
    constraints geo_types: :point, force_srid: 4326
  end

  modify_query {Panacea.Lociary.ManualNearest, :modify, []}
end

The "modified" query (I guess I'm more making one from scratch using the ash argument):

defmodule Panacea.Lociary.ManualNearest do
  import Ecto.Query

  def modify(ash_query, ecto_query) do
    
    location = ash_query.arguments.location
    modified_ecto_query =
      from listing in Panacea.Lociary.Listing,
        where: not (listing.location |> is_nil()),
        order_by: [asc: fragment("? <-> ?", listing.location, ^location)],
        limit: 10

    IO.inspect(modified_ecto_query)
    {:ok, modified_ecto_query}
  end
end

defmodule Panacea.Lociary.ManualNearest do
  import Ecto.Query

  def modify(ash_query, ecto_query) do
    
    location = ash_query.arguments.location
    modified_ecto_query =
      from listing in Panacea.Lociary.Listing,
        where: not (listing.location |> is_nil()),
        order_by: [asc: fragment("? <-> ?", listing.location, ^location)],
        limit: 10

    IO.inspect(modified_ecto_query)
    {:ok, modified_ecto_query}
  end
end

I'm going to have to filter out some obviously bad data in addition to nils (i've got some null islands and some just... strange entries) but it's working!

Creating an Identity referencing a key within a :map attribute (postgres-stored jsonb)

ok, got it. so for reference what I'm doing right now (as a "workaround", but it works the same) is just extracting the values I want to key on from the json before sending it all to ash, and I have those keys as real attributes in the resource with an identity defined on them. Working great. Those specific keys should be stable. I /would/ like, in another area, to /select and filter/ based on the contents of the jsonb, which is why I figured I'd try to jump right in with upserting on it. Is reading, filtering, etc supported? (The data has over five hundred fields in an unstable "schema", that's why I'm using jsonb. I've been informed postgres wouldn't take kindly to that many columns.)

still getting used to elixir's scope and mindset of assigning from private functions, instead of the nested if hell i find myself reaching for first. but this is sooo much cleaner 😭

okay this feels like a breakthrough, excited rn is there anything devastatingly busted about this approach? it's working :>

def handle_event("save", %{"form" => params}, socket) do

LiveView uploads with AshPhoenix.Form

EDIT: I'm getting ** (KeyError) key :wallpaper_url not found in: %{__changed__: %{}, ... when I don't change the wallpaper, so I think I might have to assign that to something at mount? But when I upload it persists now, fixed a bug with using an atom instead of a string as a key
