The first thing you need to do in order to hook into an event on your model is to use the $dispatchesEvents property to register event objects, which will eventually get fired through the HasEvents::fireCustomModelEvent() method, which is called via the fireModelEvent() method. The documentation gives an excellent overview and explains how to hook into these events, but read further if you are new or unfamiliar with how to hook up event listeners to these custom model events. However, in both cases, the saving / saved events will fire. If a model already existed in the database and the save method is called, the updating / updated events will fire.

Return $this->morphToMany(Tag::class, 'taggable') You need make sure that your pivot table model is either extending Illuminate\Database\Eloquent\Relations\MorphPivot or Illuminate\Database\Eloquent\Relations\Pivot. This will allow Laravel to start firing off these events, and for us to start listening for them. It turns out, there is a method called using that lets you define a model for your pivot table to use on the relationship. The problem is that Laravel doesn’t fire off events on a pivot table. This way existing tags won’t get updated, but newly created tags will have the propper submitted_by_id. One way around this is to listen for the events that eloquent fires off (creating, created, updating, updated, etc), specifically the creating event, and use that to set the submitted_by_id to the authenticated users id. In order to acheive this I would have to get all the current tags, and preform some kind of logic ahead of time to decide who the submitted_by_id should actually be before syncing.Īnother problem is that this tags()->sync() functionality was happening all over a code base that has no test coverage causing the refactoring process to be somewhat risky. We wanted to maintain the data of who first attached the tag to the post. ‘2’ => ,īut the problem this would create is that any existing tag would have it’s submitted_by_id changed to the new users id. One way I could of handled it was to provide an associative array where the key was the tag id and the value was an array of attributes to store on the pivot table.
