Warning: This is a silly question! 
How do I call a view function with parameters that come from a model?
I read the following example in the docs:
<a data-th-href="${portal.pageUrl({'_path=/my/page', 'a=3'})}">Link</a>
How can the path be replaced with a value from an object in the following example?
<li data-th-each="article : ${relatedArticles}">
<a data-th-text="${article.displayName}" data-th-href="???"></a>
</li>
Each article has a _path attribute.
