    <p>I'm using Middleman (and Ruby, and Rails) for the first time, and I've hit a bit of a roadblock when it comes to rendering individual pages using Redcarpet as my markdown processor, and ERb for layout.</p> <p>I want to use Markdown to style individual blocks of content, but each page will have more than one piece of content, uniquely styled.</p> <p>Rather than using partials, is there a way to instantiate the Redcarpet renderer on multiple areas of the page? So in <code>index.html.erb</code>, there would be something like this:</p> <pre><code>&lt;div class="grid5 container"&gt; &lt;% markdown do %&gt; # Some markdown &lt;% end %&gt; &lt;/div&gt; &lt;section class="grid6"&gt; &lt;% markdown do %&gt; ## More markdown &lt;% end %&gt; &lt;/section&gt; </code></pre> <p>I've tried to build a <a href="http://middlemanapp.com/helpers/#toc_9" rel="nofollow noreferrer">helper</a> <a href="http://dev.af83.com/2012/02/27/howto-extend-the-redcarpet2-markdown-lib.html" rel="nofollow noreferrer">based on</a> <a href="https://stackoverflow.com/questions/2930825/possible-to-embed-markdown-within-erb/2931834#2931834">several</a> <a href="http://asciicasts.com/episodes/272-markdown-with-redcarpet" rel="nofollow noreferrer">tutorials</a>, but I'm just not that good at Rails yet.</p> <p><strong>Edit</strong> My config.rb helper looks like:</p> <pre><code>module MD def markdown(text) Redcarpet.new(text).to_html end end helpers MD </code></pre> <p>per ASCIIcasts, linked above, and my ERb template uses similar code to the above:</p> <pre><code>&lt;span class="g6 pre3"&gt; &lt;% markdown do %&gt; ...etc... &lt;% end %&gt; </code></pre> <p>but I'm getting an error when I load the page: <code>ArgumentError at /about wrong number of arguments (0 for 1)</code></p>

    1. COI'm actually not really understanding your problem? Why does the helper built in the Railscast for example does not work multiple times in a view? Yes, it is not very performant to recreate the Renderer for every Markdown section, but it should work, right? Or do you want to know how to make it more efficient?

    2. COIt's not working at all, actually, and I can't quite figure out why. I'll update the question with the code I'm using and the error I'm getting...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
