for post in page.posts does not work with Swig

[thom4parisot]

I think it's related to the iterable properties of page.posts.

If I have this layout.swig file for example:

<ul>
{% for post in page.posts %}
  <li>{{ loop.index }} {{ loop.key }} {{ post.title }}</li>
{% endfor %}
</ul>

It will output this:

<ul>
    <li>1 _name </li>
    <li>2 _parent </li>
    <li>3 _store </li>
    <li>4 _index </li>
    <li>5 _schema </li>
    <li>6 length </li>
</ul>

Any explanation would be warmly welcomed. Twig is absolutely not documented and I'm struggling using it (for example, I discovered I needed to do {{ body | raw }} in my layout.swig to output the content of index.swig.

Thanks!

You should use page.posts.forEach or page.posts.each to iterate the posts. However, it seems that there's no way to write JS code directly in Swig template?

[thom4parisot]

None of them works :-(

Okay. I'll add Warehouse support for Swig in the next version.

Cool thanks :-)

When I iterate on page.posts._index I successfully retrieves the IDs, but obviously, it's not the populated objects.

EJS lets you execute real functions, while Swig does not want to.
To return a result, the function must be wrapped in another one (like in Mustache and Handlebars).

Thanks for answering so fast :-)

So.. is this fixed? I am getting exactly the same problem. site.posts does not output anything when iterating through it with Swig's for each loop.

Swig plugin is removed. Use site.posts.toArray() instead.
