Jason GarberWith <a href="https://indieweb.social/tags/RubyOnRails" class="mention hashtag" rel="nofollow noopener" target="_blank">#RubyOnRails</a>, you can check an <a href="https://indieweb.social/tags/ActiveRecord" class="mention hashtag" rel="nofollow noopener" target="_blank">#ActiveRecord</a> object’s validations on an attribute using `object.class.validators_on(attribute)`.The result is an array of validator classes, most of which include an `options` method with the configured options from the definition in the model.Is it possible to filter out conditional validations from the returned array?(I have a conditional validation on an attribute and would like to know when it doesn’t apply to a particular instance of the model.)

But is there something we can do to lessen the risks of people running into that by catching the issue earlier?Also, even overwriting those attributes is not possible in normal Rails code because <code>save!</code>ing will call <code>attribute_changed?</code> which will in turn try to decrypt the value to compare it, and raise an exception. Is there a way we can better handle columns that fail to decrypt when we are just interested in overriding them?
