When adding a relationship to the author, I'm unable to see any custom field
Ideally it should work... Please find exported view below which displays Author Name of last blog post.. You can able to add more fields to the same view..

$view = new view();
$view-&gt;name = 'blog_last_poster';
$view-&gt;description = '';
$view-&gt;tag = 'default';
$view-&gt;base_table = 'node';
$view-&gt;human_name = 'Blog Last Poster';

$view-&gt;api_version = '3.0';
$view-&gt;disabled = FALSE; /* Edit this to true to make a default view disabled initially */

/* Display: Master */
$handler = $view-&gt;new_display('default', 'Master', 'default');
