    <p>I'm a PHP guy on my first day in Python-land, trying to convert a php site to python (learning experience), and I'm hurting for advice. I never thought it would be so hard to use multi-dimensional arrays or dictionaries as you pythoners call them.</p> <p>So I can create multi-dimensional arrays using <a href="http://parand.com/say/index.php/2007/07/13/simple-multi-dimensional-dictionaries-in-python/" rel="nofollow noreferrer">this</a>, but i can't loop it in a django template. <a href="http://code.activestate.com/recipes/389639/" rel="nofollow noreferrer">this</a> doesnt work but i imagine i cant loop through it if i could get it to work.</p> <pre><code>{% for key,val in dictionary.items %} </code></pre> <p>only works for actual dictionaries it seems, not the custon multi-dimensional dictionary classes. </p> <p>I'm creating my dictionary from a sql query:</p> <pre><code>vid[ video[ 7 ] ][ 'cat_short_name' ] = video[ 2 ] vid[ video[ 7 ] ][ 'cat_name' ] = video[ 1 ] vid[ video[ 7 ] ][ 'cat_id' ] = video[ 7 ] vid[ video[ 7 ] ][ 'companies' ][ video[ 14 ] ][ 'comp_short_name' ] = video[ 5 ] vid[ video[ 7 ] ][ 'companies' ][ video[ 14 ] ][ 'comp_name' ] = video[ 4 ] vid[ video[ 7 ] ][ 'companies' ][ video[ 14 ] ][ 'comp_website' ] = video[ 6 ] vid[ video[ 7 ] ][ 'companies' ][ video[ 14 ] ][ 'videos' ][ video[ 8 ] ][ 'top_video' ] = 0 vid[ video[ 7 ] ][ 'companies' ][ video[ 14 ] ][ 'videos' ][ video[ 8 ] ][ 'vid_id' ] = video[ 8 ] vid[ video[ 7 ] ][ 'companies' ][ video[ 14 ] ][ 'videos' ][ video[ 8 ] ][ 'vid_name' ] = video[ 9 ] vid[ video[ 7 ] ][ 'companies' ][ video[ 14 ] ][ 'videos' ][ video[ 8 ] ][ 'vid_url' ] = video[ 10 ] </code></pre> <p>I basically need to get all companies in a certain category and then get all videos in that company so i can nest them easily in my template. This is how i did it in php, creating one huge deep array. Trying to duplicate in Python has proven difficult.</p> <p>I thought maybe i could do with the backwards lookups in django using set_MODEL but i couldn't figure that out either.</p> <p>Any help on how to accomplish my goal would be appreciated. I hope my question is clear</p> <h2>EDIT:</h2> <p>When im done looping in my template it looks like this...</p> <pre><code>&lt;h1&gt;Category&lt;/h1&gt; &lt;h2&gt;Company&lt;/h2&gt; &lt;ul&gt; &lt;li&gt;video&lt;/li&gt; &lt;/ul&gt; &lt;h2&gt;Company&lt;/h2&gt; &lt;ul&gt; &lt;li&gt;video&lt;/li&gt; &lt;li&gt;video&lt;/li&gt; &lt;/ul&gt; &lt;h1&gt;Category&lt;/h1&gt; &lt;h2&gt;Company&lt;/h2&gt; &lt;ul&gt; &lt;li&gt;video&lt;/li&gt; &lt;/ul&gt; &lt;h2&gt;Company&lt;/h2&gt; &lt;ul&gt; &lt;li&gt;video&lt;/li&gt; &lt;li&gt;video&lt;/li&gt; &lt;/ul&gt; </code></pre>

    1. COIs what you show in the edit what it does look like, as you say, or what you'd WANT it to look like? What's Category, Company and video in terms of the above complicated Python code you have?

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.
