rspec users - Sep 2007 - Can not ''assigns'' value in View test

Hello everyone:
  I am quit new to View test using rspec. I want to write spec for a
partial, which is rendered by a controller. However, the controller does not
pass data to the partial using instance variables, it uses symbol variable
instead. I read the example of view spec provided in the website. But the
example is using instance variable. So I am looking for a way of assigning
my test data to the partial to be tested. I would like to show an my code
below:
class MyController
  def index
    hash = {...#data provided here}
    render :partial=>''index'', :layout=>false,
:locals=>{:hash=>hash}
  end
end

_index.rhtml
  ......#unrelated code omitted
  <script>
    var data = <%= hash %>;
    <!-- process data here -->
  </script>

In my spec, I used assigns[:hash] = my_own_data, but an error occurred,
saying that "undefined local variable or method ''hash''
".
How can I assign my own data to hash in my view spec?
Thank you!

Granted that I''m new too; however, assigns[:hash] creates a member  
variable @hash that is made available to the view.  Maybe that''s the  
problem?  Modify your view to use @hash instead.

Unfortunately, I am not supposed to change the code inside the partial.
That''s why I posted this message. I am trying to find a way of tackling
this
problem. Because I am going to test tens of hundreds of partials, most of
which are using the symbols rather than instance variable.

Huh? Symbols in the partials that are supposed to magically transform
to some value? I don''t get it. What am I missing?

I also feel puzzled. But that''s what my colleagues do, and it works.
The
thing is they use
  render :partial=>''index'', :locals=>{:hash=>hash}
in the controller to pass the hash data to the partial it will render(index
in this case). And later they simply use <%= hash %> to get the hash data
passed from the controller. Maybe the :locals does some magical work here. I
am quite familiar with rspec and ruby. So I am reading more documentation
now.
Hopefully we could figure it out shortly.

Now THAT is a horse of a different color. OK - first:

  render :partial=>''index'', :locals=>{:hash=>hash}

Here, the symbol :hash is just a key - it is not the object that''s
been passed around.

Second:

  <%= hash %>

I''m assuming that''s in the partial named index (a partial
named
index???????, now THAT''s not at all confusing). In this case, the
:locals => {:hash=>hash} in the calling template assigns the hash
object (in the calling template''s scope) as the return value of a
method in the partial named .... (drum roll, please) .... hash. Like
hash().

So - what you want to do is to stub the hash method on the template:

  template.stub!(:hash).and_return(the_hash_I_want_to_stick_in_the_template)

That all make sense?

Good luck!

Hello, David:
  Thank you very much for your help. Now it works! 
  I would like to recall a message posted several days ago regarding the
"paginate". How to test "paginate" in controller spec? One
simple example
may be like this:
  hash[:accounts_pages], hash[:accounts] = paginate :accounts(the table),
#order and conditions follows
How should I test this code in controller spec? Or can I mock this line,
like should_receive(:paginate).and_return(...)? But the problem is
''paginate'' returns two values. :(
  Thanks for investigating this question.
