Ash.Query.filter creates filter with OR condition instead of AND
Ash.Query.filter function documentation explicitly says that a filter will be added with the AND condition, but it seems that this is not the case when fragments is used.
For example, if I do this:
```elixir...Generated filter expression is incorrect - BUG
Hello, I think I found a bug in Ash's query builder.
I have the following filter expression in my resource action:
```elixir...
Filter by struct keys in a read action
So I have an ash actions.
It receives a struct as an input.
I want to create a filter that filters by values inside the struct.
here's a simplified version of the action:...
Transactions
There appears to be several ways to handle transactions, but I'd like to really narrow in on a clean way to handle logging entries from within a transaction. Let's use a simple example such as a Post. So when I create a Post from a Phoenix LiveView, I'd like to call a wrapper action for it such as
Post.create_with_log(%{title: title})
Then in my Post resource file, I could possibly:
1) Create a code_interface definition such as define(:create, args: [:title], action: :create_with_log)...Keyset pagination doesn't seem to use default_limit value
I have this action:

Session params missing for oidc providers using response_mode: form_post (e.g. Azure AD)
I am trying to use the OIDC strategy with Azure AD. Now is Azure requiring to use
response_mode: form_post. This requires that the POST callback endpoint is not under CSRF protection (similar to how pow_assent is doing it).
The issue is that the user/<strategy> key is not in the session during the callback phase. Am I required to implement a server side session store as pow does it?
See the setup below:
...Testing: How to approach testing
Im trying to write some tests for my ash resources, and want to test errors in particular, is there a recommended way of going about this? The testing docs are a bit anemic, wonder if folks have some strategies here. In particular when matching on ash errors, I have to match on large error structs with the stacktrace. Is there a simplier way of going about this?
Why don't read actions filter by attributes?
Given a read action
```

define :read
end...
warning: Changeset has already been validated for action :create.
I am getting this warning when trying to set an attribute before submitting a form, since this isn't user provided and I don't want to make the http call if this isn't going to be submitted, is there maybe another way to accomplish this as the warning says this will be an error in the future.
```

Should I use old-fashioned DB lookup tables? What might be some alternatives?
I realize not all mapped values are the same. Some have a very small set number of KVs (int id => 5-point scale). Some have a larger (int id => country code). Some have an indefinite set of KVs.
In which cases (if not all) would you recommend DB lookup tables with Ash
relationships. Would you recommend an alternative? I had considered for small sets to use a calculation, but I think that works with reads but not writes, right?...How to: Conditional validation with built-ins
Im trying to validate an embedded field "payment_method" when a certain param/attribute has a specific value. I've tried to do this:

AshCsv - duplication on `upsert?: true`

Calculations in AshJsonApi?
Just want to make sure I'm not missing anything obvious - is it possible to include a calculation in a JsonApi request? Including one in the
