JoinFilter a change by action_type
I have a change that I want to apply to all the resource actions that are of type
create, update and destroy.
Looking at the Ash.Resource.Validation.Builtins I can only see the action_is/1 option which allows me to specific an action by name, but I can't find any action_type/1 options or something similar.
Is that not possible?...Use change manage_relationship without argument in create action.
I have a resource called
User which has a has_one relationship with another resource called ImpersonatePermissions. When I create a new user, I want to also create a new in the impersonate_permissions table. To do that, I believe that I need to use manager_relationship.
I was able to make this work with a custom change function:
```elixir...Multi-Location + Multi-Tenant Read Replica
So we have a fairly complex requirement that we are hoping to solve via schema-based multi-tenancy and PG read replicas. As you can see from the diagram, we want to host the app in the cloud + 2 onsite locations matched to tenants. We would like to leverage read replicas to enable shared reads & local tenant writes in the event of internet/power outages at one of the on-site locations.
Are there any immediately obvious problems with this idea, or does it seem feasible?...
Multiple filters giving unexpected result
Say I have a data model similar to this:
```elixir
defmodule Ht.Org do
has_many :accounts, Ht.Account ...
Create relationship with itself
How can we add a relationship from some resource to itself?
For example, let's say I have a
User resource and I add a feature that an user can create another user, meaning that I want to add a field called created_by and created_by_id which is also an User...Migration generator splitting composite primary keys
Before, I believe the recommendation was to do
many_to_many relationships like so:
```elixir
relationships do
belongs_to :resource_a, App.ResourceA, primary_key?: true, allow_nil?: false
belongs_to :resource_b, App.ResourceB, primary_key?: true, allow_nil?: false...Reading Tenant ETS resources returns empty array
I am trying to read a tenanted ets resource but always getting empty list when trying to read, though creates are "successful".
Below is my IEX session

Ash-Postgres and uuidv7
This might be an Ecto question. If I add a Postgres function uuidv7(), can Ash use it when creating new resource instances? If not, could Ash use such a function in Elixir (that would probably be faster anyway).

Hi @Zach Daniel,
related to yesterday's question (https://discord.com/channels/711271361523351632/1097912088296443904) I got a new hint: we're trying a full-spread ash adoption on our internal project and we're trying to use only resource's code-interfaces everywhere, but for yesterday
count/1 I've to call api module directly.
What about the idea of a new kind of action supported by ash resource's DSL for defining resource's metrics methods in a declarative way?
...Refresh "calculations" during form.validate
This question is kind of similar to https://discordapp.com/channels/711271361523351632/1071883200378445854/1071883200378445854
However, that example is a simple calculation involving two of the readily available form fields, whereas mine isn't as simple in that one of the inputs needs an aggregation of counts from an embedded array field as shown below. I want to be able to display the remaining count of an item which would decrease as the user increases the usage count.
```

Patterns for Propagating Tenants to LiveComponents/LiveViews?
This is a Noob / organizational question. But I just added attribute multi-tenancy to my app. I have the correct tenant loaded on login, placed in the conns, and in the session via
ash_authentication.phoenix.livesession. I am grabbing the tenant from session in a LiveView to be added to reads . For handle_events, and all LiveComponents which talk to the DB, I assume I'll need to pass the tenant in via assigns? Feels like it could get a bit messy, especially for LiveComponents. Does any...How to make simple select count with Ash
Hi,
maybe a noob question here 😅 but I'm wondering which is the right way of making a simple select count of my Users on a Postgres-based app.
I could do that with
MyApi.count(MyResource) but on the docs that method belongs to the ambigous Ash.Filter.ShadowApi module.
...GraphQL Subscriptions
Are they on the roadmap? Is there an existing pattern for getting them going using Notifiers?
