Body
In your model, add the following method: <pre><code>/** * Uses the primary keys set on a new record to either create or update * a record with those keys to have the last_access value set to the same value * as the current unsaved model. * * Returns the model with the updated last_access. Success can be checked by * examining the isNewRecord property. * * IMPORTANT: This method does not modify the existing model. **/ public function updateRecord(){ $model = self::model()->findByPk(array('user_id'=>$this->user_id,'category_id'=>$this->category_id)); //model is new, so create a copy with the keys set if(null === $model){ //we don't use clone $this as it can leave off behaviors and events $model = new self; $model->user_id = $this->user_id; $model->category_id = $this->category_id; } //At this point we have a model ready for saving, //and don't care if it is new or not $model->last_access = $this->last_access; $model->save(false); return $model; } </code></pre> The above is inspired by a more general method that I use a lot to do a create-or-find-if-already-exists process. Use the following code to execute this. <pre><code>$userCategory = new UserCategory; $userCategory->user_id = 1; $userCategory->category_id = 15; echo $userCategory->isNewRecord; //always true $userCategory->last_access = Now(); $userCategory = $userCategory->updateRecord(); </code></pre> Note that only the last line is different from your code. The fact that the instance of the model declared with <code>new UserCategory</code> is not altered is intended behavior. You can then verify in your code whether or not the model saved with the following: <pre><code>if(!$userCategory->isNewRecord){ echo 'save succeeded'; } else{ echo 'save failed'; } </code></pre>

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.
