Nope, it would be:
map.resources :courses, :has_many => [:pages, :forums]
You map it to an array. In Ruby any hash style assignments in a method
call, which this is, but must come at the end to be implicitly converted to
a hash. In the initial example you are doing this:
map.resources(:courses, {:has_many => :pages})
And that works just as well as the normal version, but it's not as readable.
If you did it your way, Ruby wouldn't be able to make the last arguments a
hash as you have just a key as the last argument (your :forums looks like an
additional argument to map.resources not a part of :has_many).
Anyway, answered in the first line of code, hopefully the rest may make it
slightly clearer.
Cheers,
Andy
