Skip field if nil doesn't include associations which are not empty

[sadda11asm]

Blueprinter.configure do |config|
  config.if = ->(field_name, obj, _options) { obj[field_name].present? }
end

I am using this to not include nil fields to the response, but it also takes all associations out too.

Is this with activerecord models? It's likely because the regular attributes are accessible with [] but associations are not - maybe try

Blueprinter.configure do |config|
  config.if = ->(field_name, obj, _options) { obj.public_send(field_name).present? }
end

Calling public_send will not work if you have custom fields in blueprint. It will throw "undefined method" error
