The document said
{# src/Acme/ArticleBundle/Resources/views/Article/recentList.html.twig #}
{% for article in articles %}
<a href="{{ path('article_show', {'slug': article.slug}) }}">
{{ article.title }}
</a>
{% endfor %}
also, can use 'url' like this:
<a href="{{ url('_welcome') }}">Home</a>
it confused me what is the difference between using 'url' and 'path'?
They are very similar.
Generates a relative/absolute path :
path('contact') will generate /contact
Generates a scheme-relative/absolute url, ie domain + path
url('contact') will generate http://example.org/contact
The url() style is useful when using cross-domain ajax or generating emails, because the hostname won't be the same.
Take a look at the code https://github.com/symfony/symfony/blob/master/src/Symfony/Bridge/Twig/Extension/RoutingExtension.php for more information
url Twig function generates absolute path path Twig function generates / related url
Example we have http://sf2sandbox.local with AcmeDemoBundle
{{ path('_welcome') }} produce /
{{ url('_welcome') }} produce http://sf2sandbox.local/
