Find a URL inside Twig file from content made from another content type (referenced/ has a relationship)
You can use path function with the route for node (entity.node.canonical) and the entry.id (node id) for your blog entry. Pass the id in with the &quot;node&quot; parameter.
&lt;a href=&quot;{{ path('entity.node.canonical', {'node': entry.id}) }}&quot;&gt;&lt;/a&gt;
