solved ...
Running the ApplicationHelper spec tests mixed the ApplicationHelper methods
into Object.
Actually I don't remember making the helper being tested or the spec ;-) Might
have been generated by restful authentication ...
Here's what's in spec/helpers/application_helper_spec.rb (which is what is
causing the problem):
require File.dirname(__FILE__) + '/../spec_helper'
include ApplicationHelper
include AuthenticatedTestHelper
describe ApplicationHelper do
describe "title" do
it "should set @page_title" do
title('hello').should be_nil
@page_title.should eql('hello')
end
it "should output container if set" do
title('hello', :h2).should have_tag('h2', 'hello')
end
end
end
Evidently self is Object when that file is loaded and mixes the methods in ApplicationHelper into Object -- not useful -- but
I'll bet I'm still doing something wrong ...
Here's what I replaced it with which works fine:
require 'spec_helper'
class ViewWithApplicationHelper < ActionView::Base
include ApplicationHelper
# When actually running in a view the controller's instance variables are
# mixed into the object that is self when rendering, but instances
# created from a class that just inherits from ActionView::Base don't have
# those instance variables (like @page_title) mixed in. So I add it by
hand.
attr_accessor :page_title
end
describe ViewWithApplicationHelper do
before(:each) do
@view = ViewWithApplicationHelper.new
end
describe "title" do
it "should set @page_title" do
@view.title('hello').should be_nil
@view.page_title.should eql('hello')
end
it "should output container if set" do
@view.title('hello', :h2).should have_tag('h2', 'hello')
end
end
end

to find this problem.
