    <p>Usually it's better for functions to have one job. Your get_biography() function has 2: get one biography and get all biographies. Consider splitting them up into 2 functions. Also there's no need for the multiple db access.</p> <pre><code>public function get_biography($id=null) { $this-&gt;db-&gt;where('id', $this-&gt;get_property($id)) $query = $this-&gt;db-&gt;get('biography_content'); foreach($query-&gt;row() as $key =&gt; $value) { $this-&gt;set_property($key, $value); } } public function get_biographies() { $biography_list = array(); // don't limit this query to just id's - get everything $query = $this-&gt;db-&gt;get('biography_content'); // For each record, return a new biography_model object foreach($query-&gt;result() as $row) { $model = new biography_model(); // set the properties you already have straight onto the new model // instead of querying again with just the id foreach($row as $key =&gt; $value) { $model-&gt;set_property($key, $value); } $biography_list[] = $model; } return $biography_list; } </code></pre> <p>Also you might want to take advantage of php's <code>__get</code> and <code>__set</code> magic methods:</p> <pre><code>public function __get($property) { if(!isset($this-&gt;$property)) return null; return $this-&gt;$property; } public function __set($property, $value) { if(!property_exists($this, $property)) return; if($property == 'image_file_name') { $this-&gt;image_url = $this-&gt;get_bio_img_url($value); } else $this-&gt;$property = $value; } </code></pre> <p>This will let you get properties on your model like this: <code>$bio-&gt;title</code> instead of <code>$bio-&gt;get_property('title')</code> while at the same time provide a place you can introduce new logic later.</p>

    1. COI confess I was not aware of the __set and __get magic methods. I found notes suggesting that there is high overhead with using these methods, so I modified the pages served by this biography_model and profiled the performance before and after changing to __get and __set and I really cannot measure or detect a difference. Also, point taken on breaking out get_biography function into two methods. For some reason I was focused on having the object set its own properties on instantiation, so I overlooked simply setting them directly as suggested. Thanks, -Wolf

Querying!

 
Guidance
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.
