Hrm...that's exactly what I'd started with, and I was getting the following
error:
Failures:
1) WidgetsController GET 'index' should provide a collection of widgets in
@widgets
Failure/Error: assigns[:widgets].should include(widget)
expected [] to include #<Widget:0x81686290 @name="Widget_1001">
Stupidly, I had defined my controller method as:
def index
@widgets = Widget.find(:all)
end
Changed that assignment to Widget.all...problem solved.
