  • 8. Local commands $ paster addcontent --list-all $ paster addcontent contenttype $ paster addcontent portlet $ paster addcontent view
  • 9. Clean up! ExampleTypeSchema['title'].storage = atapi.AnnotationStorage() ExampleTypeSchema['description'].storage = atapi.AnnotationStorage() ... class ExampleType(base.ATCTContent): ... title = atapi.ATFieldProperty('title') description = atapi.ATFieldProperty('description')
