I am creating a custom read action to get students by :roll_number and :password.
defmodule MyApp.Students.Student do
use Ash.Resource,
domain: MyApp.Students,
data_layer: AshPostgres.DataLayer,
extensions: [
AshJsonApi.Resource
]
json_api do
type "student"
routes do
base("/students")
get(:read, route: ":id")
index :read
get(:get_by_roll, route: "by_roll")
end
end
actions do
read :read do
primary? true
end
read :get_by_roll do
argument :roll_number, :string, allow_nil?: false
argument :password, :string, allow_nil?: false
filter expr(roll_number == ^arg(:roll_number) && password == ^arg(:password))
end
end
postgres do
table "students"
repo MyApp.Repo
end
attributes do
attribute :id, :uuid do
writable? false
primary_key? true
default &Ecto.UUID.generate/0
allow_nil? false
public? true
end
attribute :first_name, :string do
allow_nil? false
public? true
end
attribute :last_name, :string do
allow_nil? false
public? true
end
attribute :class, :string, public?: true
attribute :section, :string, public?: true
attribute :dob, :date, public?: true
attribute :father_name, :string, public?: true
attribute :mother_name, :string, public?: true
attribute :roll_number, :string, public?: true
attribute :password, :string, public?: true
create_timestamp :inserted_at
update_timestamp :updated_at
end
end
API Endpoint call
localhost:4000/api/students/by_roll?roll_number=100&password=sakthibalan@100

The fact that we aren’t handling the error there is bad, please open an issue on ash_json_api. To resolve it, add
”ash-functions”to your installed extensions in your repo, and generate migrations.EDIT: or use
andinstead of&&Sakthibalan
Yes, I already included “ash-functions”.
It’s working good after did this changes EDIT: or use
andinstead of&&Thank you!
