Navigation menu in PieCrust

Here’s another post in the PieCrust cookbook series, this time focusing on a classic web-design pattern: the navigation menu.

Menu

It’s really just a bunch of links that you can put somewhere around each page’s content, but the trick here is to tell the user which page he’s currently on. This is pretty easy to do using Twig macros and the data exposed by PieCrust, assuming of course you’re using PieCrust’s default template engine.

Article drafts in PieCrust

A common feature of a blog engine is to let the user work on an article for a while before actually publishing it. Thanks to pagination filtering, it’s pretty easy to do in PieCrust.

All you have to do is add the following to your blog’s home page’s configuration header:

posts_filters:
    not:
        has_tags: draft

This will skip any post that has the draft tag.

You will probably need to add some similar filtering to other pages such as the _tag or _category pages.

Edit: as Keilaron mentioned in the comment, you can’t modify the filters on a tag or category listing page, because their filters are preset to, well, filtering posts with a specific tag or category. This means that, unfortunately, you should not actually tag/categorize your drafts.

Edit 2: as of PieCrust 1.0, it’s possible to use a posts_filters on the _tag or _category pages, so it’s all good!


Using Mercurial to publish a PieCrust website

These days, all the cool hipster kids want to deploy stuff by pushing a Git or Mercurial repository up to their server.

And that’s pretty cool indeed, because you basically update your website by doing something like:

hg push myserver

So here’s how you can do it with PieCrust (although 90% of this article has nothing to do with PieCrust):

  1. Installing Git/Mercurial/whatever on your server
  2. Setting up your SSH keys
  3. Pushing your repository
  4. Defining hooks/triggers

Enabling Disqus' developer mode

This is the second post of a series of things I learned while using PieCrust.

From the Disqus documentation:

[You can tell] the Disqus service that you are testing the system on an inaccessible website, e.g. secured staging server or a local environment. If disqus_developer is off or undefined, Disqus’ default behavior will be to attempt to read the location of your page and validate the URL. If unsuccessful, Disqus will not load. Use this variable to get around this restriction while you are testing on an inaccessible website.

Assuming you will be baking your final website, you basically want this disqus_developer variable to be enabled if you’re not baking (i.e. you let PieCrust server each page dynamically), or if you’re baking from the chef server. And because both the baker and the server define variables you can access from your templates and pages, you can write this:

{% if not baker.is_baking or server.is_hosting %}{{ disqus.dev() }}{% endif %}

That’s assuming you’re using the default template engine (Twig), and that you have a disqus.dev macro defined somewhere in your template paths with the following code:

{% macro dev() %}
<script type="text/javascript">
    var disqus_developer = 1;
</script>
{% endmacro %}
