Be sure to review the changes made to the blog tutorial.
Some specific changes to note we pass model names in inputTag().
was: $html->inputTag('title', 40)
now: $html->inputTag('post/title', 40)

Also in the tagErrorMsg() we pass the model name.
was: $html->tagErrorMsg('body', 'Body is required.')
now: $html->tagErrorMsg('post/body', 'Body is required.')
