I have been testing if it's possible to use attributes of associated
objects in create_permitted? like this (just an imaginary example):
belongs_to :resource
def create_permitted?
resource.building.name == 'Foo'
end
This gives nil when trying to open up a form for creating new entries:
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.building

Should I be able to use associations like this and I have stumbled on
a bug or is what I am trying to do invalid? This is with hobo-0.8.7. I
can write something to the manual if the associations are expected to
be nil in create_permitted?. When thinking about it for the framework
to be able to do New links properly etc it would make sense that
checking like this is not possible.
