Hi, I’m learning Elixir and trying to make a custom changeset validation to check if a given list has any empty values.
I am piping this into my changeset
|> validate_array_field(:array_field)
And here is where I want to do the validation
defp validate_array_field(changeset, field, opts \\ []) do
# ???
end
I can’t figure out a way to validate if ANY value in the list is empty. For example,
["a", "b", "", "c"] should return errors because one value is empty
["a", "b", " ", "c"] should also return errors even if there is whitespace
Only when the array field looks like this: ["a", "b", "c", "d"] it should pass validation.
How would I be able to do this?
