I’m sure this must be a trivial thing to do, but in looking through the documentation so far I have not figured this out. I’m trying to make a simple read action that does a substring search and the syntax is just not clear to me. Feel free to RTFM me, but please point me to the right place in the docs ![]()
Here’s what I’ve tried:
read :query do
argument :query, :string, allow_nil?: false
filter expr(contains(name, ^arg[:query]))
end
This fails compilation with undefined function contains/2 (there is no such import)

Oh, wait it’s
^arg(:query)zachdaniel
Doesn’t explain the error about contains/2 though

As for documentation:
Examples in
Ash.Querydocs: Ash.Query — ash v3.29.3Examples in the
Ash.ResourceDSL docs: Ash.Resource — ash v3.29.3Expression reference: Expressions — ash v3.29.3

Yup, this was it! Derp. I need to pair more
The contains thing was weird though. I swear I copied that from the terminal, but when I put the code back to what I had, now I get much more helpful error about
undefined variable arg. At least that probably would have pointed me in the right direction.For posterity, this worked like a champ:
I’m sure this can be cleaned up a little, but in case someone stumbles upon this looking for the example I was looking for its a start.
