rspec users - Jun 2008 - RSpec Story - SystemStackError: stack level too deep

I have a story that executes the following (as an example to show the
bug I''m experiencing):

----------------------------------------------

  Given "I have a fake post saved" do
    @postCount = Post.find(:all).length
    @post = Post.new
      @post.employee_id = 123
    @post.name = "Name of the Post"
    @post.description = "Description of the Post"
    @post.save
  end

  Given "I have visited some page" do
    get("/posts/")
  end

  When "I get some other page" do
    get(''/posts/''+ at post.id)
  end

  Then "my variable should still be set" do
    Post.find(:all).length.should == 1 + @postCount
  end

----------------------------------------------

It fails with "SystemStackError: stack level too deep" on the
"When I
get some other page" bit.  If I remove the + at post.id bit, OR if I switch
the order execution of the Given statements, the story works.  What''s
going on?  Is this a bug, or am I just missing something?

Additionally, I''ve tried updating to RSpec Edge by running
"script/plugin install git://github.com/dchelimsky/rspec", but I keep
receiving Plugin not found: ["git://github.com/dchelimsky/rspec"].

Hi Ben,

This is probably not an rspec issue, but a rails defect
( http://dev.rubyonrails.org/ticket/10896 ). 
>From your code, I am assuming you are story testing a Rails app. I was
bitten by this too recently... Took me a while to figure it out. The
workaround is to replace

post.id

by 

post[:id]


Looks ugly, but it works. 

On your second question, my guess is the script/install plugin from git
only works as of rails 2.1.0 . At least that is what I understood from
reading

http://github.com/dchelimsky/rspec-rails/wikis/home

I followed the steps under "Install an RSpec release >= 1.1.4:" and
that
worked on 2.0.2 .

Hope this helps,

Willem van den Ende
p.s. I just joined the mailing list and found Ben''s question in the
archive. it didn''t seem to have an answer yet. apologies for double
posting if it already has
p.s II. I got hooked on story testing after seeing David Chelimsky''s
presentation at qcon london this spring.
