No specific design goal as such - other than to get the ability to use the same verbs for both editing entries and comments.

You could denote the type of object being edited using the first param to the method.

foo/blog/edit/b/27 (edits blog id #27)
foo/blog/edit/c/42 (edit comment id #42)

I'm assuming comments and blogs are in separate tables? If not, then you don't need to differentiate, as you can deduce type from ID#.

If they are, you could have:

Code:

// in controller Blog
function edit ( $type = 'c', $id = 'new' )  {
    if ($id == 'new')
        // it's a new post / comment

I've digressed into a merging of initial post() and subsequent edit() functions there. A matter of taste, but DRY tends to lead you down that path.
