Yes, I could write some JavaScript to inspect the text fields on their change event, and then toggle a hidden _destroy param to cover the third use-case, but this has some significant downsides, compared to :destroy_if solution that I'm proposing here.
1. Decreased locality. Logic to handle nested params would be both in the model, and also in the client in JavaScript 2. Increased complexity. The JavaScript component is more lines of code, and thus more things that can go wrong. What if the client is running NoScript, etc? 3. Code duplication. The predicate logic that is passed to :ignore_if would have to also be written in JavaScript. Compared to this, :destroy_if appears to be a much simpler and cleaner solution, and has none of these downsides. .
