Documentation: Perch Blog: Page Functions: perch_blog_post

I believe the documentation for perch_blog_post leads users down the wrong path.

For example, when I added the following to my page:

<?php perch_blog_post(perch_get('2014-06-09-elston-avenue-mural-project')); ?>

Nothing rendered on the page. <?php PerchUtil::output_debug(); ?> reported this:

SELECT p.* FROM perch2_blog_posts p WHERE postStatus='Published' AND postDateTime<='2014-08-14 20:01:00' AND postSlug=''

But when I added only the blog slug as the argument as follows:

<?php perch_blog_post('2014-06-09-elston-avenue-mural-project'); ?>

The page rendered the correct blog with the post.html template.

Thanks for listening.
