Description
Describe the bug
I extracted a macro into a reusable module, like this:
module ReusableRule
extend ::ActiveSupport::Concern
included do
register_macro(:reusable_macro) do
# do some validations here
end
end
end
and use it like this:
class SomeContracr < ::Dry::Validation::Contract
params do
# define some params here
end
include ::ReusableRule
rule(path_to: :inner_hash).validate(:reusable_macro)
end
which works fine.
But I cannot use it on the root hash, like this:
class SomeContracr < ::Dry::Validation::Contract
params do
# define some params here
end
include ::ReusableRule
rule.validate(:reusable_macro)
end
Expected behavior
The macro should validate the root hash the same way as when I use it on an inner hash.
Actual behavior
dry-validation throws an ArgumentError
lib/dry/validation/values.rb:59:in `[]': +key+ must be a valid path specification (ArgumentError)
My environment
- Ruby version: 3.0
- OS: Docker image (Debian)
Suggestion
Probably adding
return data if args.size < 1
around here.
