Body
<p>I need to add a number of really complex dynamic HTML structures to my Velocity template. If I were to attempt to write these directly in the template, it would be an absolute mess.</p> <p>Let me explain what I'm trying to do... let's say, on my website, a user can post comments. Rather than writing all the complex dynamic HTML structure that goes into the comments table and the posting form, I would like to be able to do this in my template:</p> <pre><code><div> // call to a method that generates the comments table </div> <div> // call to a method that generates the comments form </div> </code></pre> <p>In Ruby On Rails, there are things called <a href="http://paulsturgess.co.uk/articles/show/49-using-helper-methods-in-ruby-on-rails" rel="nofollow">helpers</a> that allow you, from the templates, to call, basically, a method that returns a dynamically-generated chunk of HTML, to be embedded in the template right where you call it. The nice thing about helpers is that you only spend CPU on the ones you use. With the <code>VelocityContext.put()</code> method, it seems like I have to generate everything I need in advance. This is a problem because I will ultimately have some 50 different helpers, and I need the non-programmer web designer to be able to swap them in and out at will.</p> <p>So I am asking,</p> <ol> <li>Can I do something like this with Velocity?</li> <li>If not, can I do something like this with some other template engine?</li> <li>Is there a better way to do what I'm trying to do?</li> </ol>

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.
