... ...Why store temporary sign in tokens and how to prune them?
Hey. ash_authentication with
store_all_tokens? indeed stores all tokens, INCLUDING temporary sign in tokens when sign_in_tokens_enabled is enabled.
First of all, I'm not sure if it's intended behavior. Why do we need to store a tmp token for sign in?
Secondly, I can't find a way to prune it from my DB. I delete the actual token on user sign out, same way as ash_hq does, but I don't have access to that temporary token to delete it -> this leads to handing outdated records in tokens table....Building an aggregates-only Resource
I'm building an admin dashboard that will display several aggregate data points sourced from different database tables. These data points should be available from a single AshGraphql query. How would you do this?
I created a resource called
Dashboard. My first approach was to create a calculation to calculate a data point. That wasn't going anywhere, so I defined an primary read action that loaded the data point from inside the prepare block. That's where I'm at so far. The problem is that calling read() on the API returns nil.
Here is an example of the kind of data I want to expose:...Is Ash well suited to Domain Driven Design
Hi everyone. First up, I'm new to Elixir and Ash and expect a steepish though enjoyable learning curve. 🤞 (I have lots of experience in other languages: Java, Go, Python, C#, VB :D, SQL etc.)
I'm redesigning a complex solution that has ~8 "micro" services (mostly Go and Java), uses Drools (with dynamic code generation) for complex business rules, Apache Pulsar for messaging, Postgres databases, Angular SPA...
In fact, it's TOO complex and unmanageable for a very small team, (1-2 ppl) and for various reasons the solution was never completed and released!
I've been following DDD principles and have a good handle on the domains, actors, bounded contexts, messages/events etc....
Ecto.Multi like transactions
Hi Ash community,
I'm looking to find some examples around how to bundle together database operations into one transaction. Like in Ecto.Multi.
In practice I would like to do something like create or update operation where entry's existence is being checked before creation. In one transaction. ...
How to write complex query with fragments

attribute match constraints error message
When validating email format using regex, is there an easier way to show a more user friendly validation error message such as "invalid email format" rather than the default "must match the pattern ~r/[a-z...."?
I believe it can be done inside action definition, but thought I might be missing an easier way to do the same in the attribute definition.
```

How to bypass ConfirmationHookChange in a specific action
In my resource, I set
monitor_fields to be [:email].
Now I want to add an action that it "forcefully" change the user e-mail bypassing the whole confirmation process.
Basically the idea is to use that function as an admin-only function....How does AshAuthentication monitor_fields work?
I was looking into the confirmation addon for AshAuthentication and started wondering what is needed to make monitor_fields work.
For example, I have that field set as
monitor_fields: [:email]
What exactly does that do? Does it "automagically" inserts a change on each action that can change the email field?...Generic action has `api` nil in context when called from `code_interface`

manage_relationship :remove across API's
I have a
Tag resource that belongs in the Organization API, I have a Transaction resource that belongs in the Transactions API, there is a join resource between them called TransactionTag that is in the Transaction API registry.
I am unable to manage_relationship :remove a Tag from a Transaction resource unless I also include the TransactionTag resource in the Organization registry. (I get a ResourceNotAllowed error otherwise)
Is this expected behaviour? ...Where do I find documentation on `contains()` , for use within an Ash.Query.filter()?
I checked:
1. Ash.Filter: https://ash-hq.org/docs/module/ash/latest/ash-filter
2. Ash.Query: https://ash-hq.org/docs/module/ash/latest/ash-query
2. Ash.Query.filter() (which was not in alphabetical order in the
Ash.Query functions list on the right side): https://ash-hq.org/docs/module/ash/latest/ash-query#macro-filter-2
...Primary key as string (not UUID)
I have an existing table with a string key. In Ecto, this was generated in the changeset function. In the Ash documentation, there is only
integer_primary_key(), and uuid_primary_key(). If I try leaving either of those out, it returns an error that says I need to specify a primary key. How can this be made to work?How to determine API boundaries?
Hello, just wondering if I can get some guidance on how to think about APIs in Ash. I'm trying to add Ash to an existing application, and just not quite sure where to begin. Should I just start with a single API, focus on resources and break it out later? Curious to hear your thoughts.
Any examples of using can?
I'm trying to see if a user (actor) can perform an update action on target user.
```
iex(9)> MyApp.Users.can?({target_user, :update}, actor)

Simulating arguments on relationships with calculations
I've seen questions related to this come up in various forms pretty regularly over the last few months, and given the outcome of https://github.com/ash-project/ash/issues/375, I thought it might be helpful to collect a series of examples for common patterns in simulating parameterized relationships with calculations.
Happy to turn the output of this into a patch to the docs for a new guide, or new section of the Calculations guide....
An aggregate field loaded in create action isn't available for pub_sub?
publish :create, ["update", :aggregate_field1] in one of my resources fails with the following error, despite the fact that change load(:aggregate_field1) is in the action definition. If I remove the publish setting from pub_sub, the create action succeeds, with the :aggregate_field1 properly loaded to the changeset.
I wonder if something changed about how pub_sub works in Ash lately, because my pub_sub and create action codes used to work fine. I did recently update ash to the latest version. Thanks....Policies Usage
I am guessing policies always get evaluated before the action is called. Can I set an argument based on the results of a policies evaluation ?
