  1. PORails creating a thumbnail gallery in my view
    text
    copied!<p>I currently have an Array that contains some URL's to images. </p> <p><code>@images = [ "http://site/images/01.jpg", "http://site/images/02.jpg" ]</code></p> <p><strong>Total 18 images</strong></p> <p>I would like to take this array and create a thumbnail gallery where <strong>the gallery is 3 columns across in my view</strong>. The HTML out put would be</p> <p><code> &lt;table&gt;<br> &lt;tr&gt;<br> &lt;td&gt;&lt;img src="http://site/images/01.jpg"&gt;&lt;/td&gt;<br> &lt;td&gt;&lt;img src="http://site/images/02.jpg"&gt;&lt;/td&gt;<br> &lt;td&gt;&lt;img src="http://site/images/03.jpg"&gt;&lt;/td&gt;<br> &lt;/tr&gt;<br> &lt;tr&gt;<br> &lt;td&gt;&lt;img src="http://site/images/04.jpg"&gt;&lt;/td&gt;<br> &lt;td&gt;&lt;img src="http://site/images/05.jpg"&gt;&lt;/td&gt;<br> &lt;td&gt;&lt;img src="http://site/images/06.jpg"&gt;&lt;/td&gt;<br> &lt;/tr&gt;<br> &lt;/table&gt;</code></p> <p>My <strong>current implementation</strong> gets me a one column table</p> <p><code>&lt;table&gt;</code><br> <code>&lt;tr&gt;</code><br> <code>&lt;% @images.each do | image | %&gt;</code><br> <code>&lt;td&gt;&lt;%= image_tag(image)%&gt;&lt;/td&gt;&lt;br&gt;</code><br> <code>&lt;% end %&gt;</code><br> <code>&lt;/tr&gt;</code><br> <code>&lt;/table&gt;</code> </p> <p>In the future I might want it to be 6 columns instead of 3 columns. I'm looking for a way to do this in a clean and flexible way.</p> <p>I was looking at the <strong>Ruby documentation</strong> and I saw this <strong>Class Range (rng.step method)</strong> <a href="http://www.ruby-doc.org/core/classes/Range.html" rel="nofollow">http://www.ruby-doc.org/core/classes/Range.html</a></p> <p>Not sure if this Range class <strong>step method</strong> can solve the problem but the example it provides is interesting.</p> <p>Any thoughts, I'm still learning and maybe I'm over thinking this?</p>
