{{ for post in posts:}}

   <h2>

     <a href="{{=URL(r=request,f='view_post',args=post.id)}}">

       {{=post.title}}

     </a>

   </h2>

{{=WIKI(post.body|truncate:30)}}

{{pass}}

if post.body is a string, you can do post.body[:30]  like you would do with a normal python string. You can't get fancy with a post.body[:27] + '...' just for the sake of being "polite.

The problem in your code is that you're "truncating" a source of something that needs to be truncated at the right position.....e.g. if you're inside a blockquote and you don't close the "quote", you'll be left with an "uncorrect" representation of the truncated markmin .....

e.g.

- a list
-- ``web2py
lorem ipsum etcetcetc
...
....
``:code

if your truncation leaves the last line out, the generated HTML might not be correct.
