Incorporates #488, using alias_method instead of alias for consistency. Thanks, @jtrim!

Addresses a regression previously addressed in #92. The regression directly affects how nested forms are rendered for has_many associations decorated with 'decorates_associations'.


Thanks for picking this up! However, I think maybe what you intended to do was something along the lines of:

alias_method :orig_kind_of, :kind_of
def kind_of?(klass)
  decorated_collection.kind_of?(klass) || orig_kind_of(klass)
alias :is_a? :kind_of?

The line that you replaced in 63721db is necessary as long as we want to maintain the is_a? api likeness to kind_of?. If this is the case, I'm not sure I see the benefit of using alias_method to define an extra instance method as opposed to calling through to super. I could very well be missing something though.

The JRuby failures are Travis' fault, so I'm not worrying about that. It's fixed in edge bundler/rubygems, they should be releasing/updating soonish.

I think that this is fine, both of them work, but this way, we don't have the extra method lying around.

@steveklabnik 👍

@jtrim alias and alias_method are pretty much equivalent, and we have tended to use alias_method throughout so I only changed it for consistency's sake... it does exactly the same thing as your version.


Yeah, I tend to prefer plain alias because of the internal Ruby optimizations it provides, but in terms of behavior you're right on equivalency. Sorry about my previous comment - I saw the build failure and jumped to a conclusion about alias_method usage. Thanks for pulling this in!
