Hello,

I’ve been going through the Rails code today, looking for a method  
that will allow me to save an invalid record, but only update  
attributes that do not have errors attached. (i.e.  
model.errors.on(:attribute) is nil).

Any ideas on how to accomplish this would be appreciated. If this  
isn’t a part of Rails, I think it would be used enough to be a good  
idea for a patch.

Thanks,  
Brady
