Body
I have the following ActiveRecord classes: <pre><code>class User < ActiveRecord::Base cattr_accessor :current_user has_many :batch_records end class BatchRecord < ActiveRecord::Base belongs_to :user named_scope :current_user, lambda { { :conditions => { :user_id => User.current_user && User.current_user.id } } } end </code></pre> and I'm trying to test the <code>named_scope :current_user</code> using <a href="http://shoulda.thoughtbott.com/" rel="nofollow noreferrer" title="Shoulda">Shoulda</a> but the following does not work. <pre><code>class BatchRecordTest < ActiveSupport::TestCase setup do User.current_user = Factory(:user) end should_have_named_scope :current_user, :conditions => { :assigned_to_id => User.current_user } end </code></pre> The reason it doesn't work is because the call to <code>User.current_user</code> in the <code>should_have_named_scope</code> method is being evaluated when the class is being defined and I'm change the value of <code>current_user</code> afterwards in the <code>setup</code> block when running the test. Here is what I did come up with to test this named_scope: <pre><code>class BatchRecordTest < ActiveSupport::TestCase context "with User.current_user set" do setup do mock_user = flexmock('user', :id => 1) flexmock(User).should_receive(:current_user).and_return(mock_user) end should_have_named_scope :current_user, :conditions => { :assigned_to_id => 1 } end end </code></pre> So how would you test this using <a href="http://shoulda.thoughtbott.com/" rel="nofollow noreferrer" title="Shoulda">Shoulda</a>?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
