Comment on You have a nil object when you didn’t expect it! by Duke

Check out this little snippet:
def carefully(default = nil)
begin
yield
rescue NoMethodError => e
raise unless e.message["You have a nil object"]
default
end
end

carefully { @object.association.variable }

It only rescues when it’s dereferencing a nil, rather than on any error. In view code, and aesthetically, I do sort of prefer yours though.

Comment on Override default find conditions for model by PhilT

Thanks. Just what I was looking for.

To answer AJ (a little late I know), you want to open up ActiveRecord::Base class (create a file in lib or an initializer then just do class ActiveRecord::Base) and alias the find method then use the code above and call the aliased method instead of super.

As for non-deleted in the example above you could just call ActiveRecord::Base.find directly but if you’ve aliased the method you’ll want to call that instead.

Thats cool too. Will that still work if the user has javascript turned off?

I use href=”javascript:void(0)”. I think it’s neater.
