Shouldn't Documentation on Delegated Types Encourage Association Validation?

Hi there!

As the title suggests, I’m using delegated types for the first time. After getting everything working as intended, it struck me that validating the associated delegated type’s record seems crucial for this pattern to work effectively.

I noticed a related question was asked quite a while ago. However, the documentation still doesn’t explicitly recommend this validation. I’m uncertain if this is considered as good or bad practice, which is why I’m bringing it up now.

Am I missing something? Are there scenarios where we wouldn’t want to have this validation?

Thanks in advance for any insights or production examples you can share!

Not sure if it works, but have you tried ActiveRecord::Validations::ClassMethods

Hi Eelco,

Yes I’m talking about this validation. In my case this works well. This is why, in my original post, I’m asking why this is still not recommended by the rails guides when using delegated types.
