栏杆|黄瓜| acl9 |禁止进入

我正在提高黄瓜的产量,我在第一次通过测试时遇到了一个问题。我得到的例外是:

And I visit the new contract screen
  Acl9::AccessDenied (Acl9::AccessDenied)
  /usr/local/lib/ruby/1.8/benchmark.rb:308:in `realtime'
  (eval):2:in `visit'
  ./features/step_definitions/manage_contracts_steps.rb:2:in `/^I visit the (.*) screen$/'
  features/manage_contracts.feature:15:in `And I visit the new contract screen'

这是我的黄瓜特征。。。

Background:
Given the following user records
| login  | password | name | role         |
| bob    | secret   | Bob  | 'PSCM Staff' |
| admin  | secret   | Frank| admin        |

@new
Scenario: Create Contract
When I log in as "bob" with password "secret"
And I visit the new contract screen
Then I should see "Contract Name"

My steps.rb:

Given /^the following user records$/ do |table|
   table.hashes.each do |hash|
     role = hash.delete('role')
     u = Factory(:user, hash)
     u.has_role!(role) if role
   end
end

When /^I visit the (.*) screen$/ do |screen|
  visit path_to(screen)
end

最后,在my controller.rb中,我有以下访问控制块:

  before_filter :load_contract, :except => [:cancel_action,:new,:create]

  access_control do
    allow :admin
    allow logged_in, :to => [:index,:show,:log]
    allow "PSCM Staff", :to => [:new,:create]
    allow :editor, :of => :contract
  end

当我在浏览器中明确地遵循这些步骤时,senario工作得很好。
