Being able to have groups of validations, partial validations, or  
validations that don’t prevent saving an object are common needs w/  
ActiveRecord. Last week I did an exhaustive search of the available  
plugins, and I wasn’t able to find anything that satisfactorily solved  
all the problems. Either things were too verbose, too limiting, too  
specific, or I just didn’t like the API.

Enter validation\_scopes. I wrote this plugin to solve my problems  
while still being able to harness the full power of ActiveRecord  
validation.

If you have interest in such a thing please give it a try. At less  
than 50 lines, I think it’s a sustainable approach that will port well  
to Rails 3, but it’s also very dense meta-programming, so I want to  
get more people using it to shake out bugs around the edge cases.

Just a general question after quickly looking over it, can you create  
new scopes that won’t let you save? or would this be accomplished  
through something like f.save if f.no\_warnings?

Thanks,

Sadly no, that wasn’t really in my use case. You might like this one

Thanks for the reference, your plugin looks pretty good, I’ll try to  
give you some feedback if I end up using it.
