Well, that was certainly a stupid mistake...figured it out with this:
it "should render the new widget layout form" do
widget = stub_model(Widget, :id => "1")
assign(:widget, widget)
params[:widget_id] = widget.id
assign(:widget_layout, mock_model(WidgetLayout).as_null_object)
render
rendered.should have_selector("form", :method => "post", :action =>
widget_widget_layout_path(widget))
end
Now, can anyone provide some insight on a more elegant #form_for call for me?
Thanks again,
Brennon
