rspec users - Feb 2009 - [rspec] [rails] Specing a form builder

I''m trying to set up and run a new form builder under rails, which
lives
under the helpers directory, but isn''t really a helper.  (Not a module,
so
doesn''t mix in well)

Short of dropping down into a view spec, how do I set up to actually spec
the form builder?

describe RandomFormBuilder do
  attr_reader  :builder
  before do
    @object = mock_model(Foo)
    @builder = RandomFormBuilder.new(:foo, @object, #template#, {}, nil)
  end

  describe "#text_field" do
    it "should have a label" do
       @builder.text_field(:foo).should have_tag("label",
"Foo")
    end
  end
end

class RandomFormBuilder < ActionView::Helpers::FormBuilder
  def  text_field(method, *args)
    label(method)
    super(method, *args)
  end
end

That''s sort of what I''ve got at the moment.  #template#
supposed to be an
object with access to all the normal helpers, I _think_.
using helper in that location gives me a NoMethodError.

using self in that location ends up with the helper trying to delegate
methods to Spec::Rails::Example::RailsExampleGroup::Subclass ....


has anybody figured out what hoops this needs?

got it.  The normal FormBuilder class uses template as a pass through for
the basic form fields.

before do
  helper = Object.new.extend ActionView::Helpers::FormHelper
  @object = mock_model(Foo)
  @builder = RandomFormBuilder(:foo, @object, helper, {}, nil)
end

then all works beautifully.
