Conditional filters in read actions
Hi there, I'm back with another quesion that i couldnt find an answer to - sorry if i missed something.
I have a resource with a list of form submissions, where i have a read action to get all form submission of a specific form id, with the form_id as an argument. that works fine.
Now i also want to add the possibility to get all records submitted after a specific date, which also works this way:
filter expr(submission_time >= ^arg(:min_submission_time)).
Now, the :min_submission_time argument is optional - i want to be able to use the same action for getting both all as well as the filtered submissions. Is there a way to have a conditional in the action to only apply the :min_submission_time filter if the argument is not nil? As far as I know the action code is evaluated at compile time, so i cant use a normal elixir if/else.
I am aware that i could just split this up into 2 different actions, but that would require duplicating things like the default sort order and filtering by form id.
Thanks!21 replies

Ash Relationships with existing Ecto Repos
Hi there,
I'm currently working on integrating Ash into my existing Phoenix/Ecto/Postgres app. So far Ash looks amazing and seems to be exactly what I'm looking for - the power and balance of ecto but without having to create basic utility functions over and over and over again 😉
Sorry if my question has already been answered, I couldn't find anything on GH, google, docs or Discord.
However I don't yet want to migrate all my existing Ecto (Phoenix Context) resources all at once, but go step by step.
Now, I added a new Repo, Registry and API with a new resource and that works fine. However now I want to add a :belongs_to in my new resource's :relationships - and that needs to be a user, so the resource belongs to a user.
Thing is, the User resource already exists as a normal Ecto schema that is used in my app, so ash tells me it can't find the resource. Is there some way to have a "compatibility" layer between an existing ecto schema and an ash resource?
Thanks!
