Laravel Updated Event (Observer): SQLSTATE[22001] Error

Question

I'm trying to append the species' ID to its name at the event of an update through an observer, but for some reason it's somewhat getting looped hence the SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column error:

SpeciesController@update

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \App\Species  $species
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, Species $species)
    {
        $species->name = $request->name;
        $species->sort = $request->sort;

        $species->save();

        $updatedSpecies = new SpeciesResource($species);

        return response()->json(compact('updatedSpecies'), 200);
    }

SpeciesObserver@updated

    /**
     * Handle the species "updated" event.
     *
     * @param  \App\Species  $species
     * @return void
     */
    public function updated(Species $species)
    {
        $species->name = "$species->name - $species->id";

        $species->save();
    }

The updated event is always fired because you're also saving it inside. Use the updating event instead.

/**
 * Handle the species "updating" event.
 *
 * @param  \App\Species  $species
 * @return void
 */
public function updating(Species $species)
{
    $species->name = "$species->name - $species->id";
}
