Cache Not Working Along with Observer

[robinhoo1973]

Describe the bug
As the Model Article content field is stored the rich text with base64 encoded string, and an observer was created for encoding & decoding while saving and reading. It works fine until the trait mode Cachable involved in the Article model. And when it removed from the model, everything returned ok.

Eloquent Query
Please provide the complete eloquent query that caused the bug, for example:
Observer
/app/Observers/ArticleObserver.php

<?php

namespace App\Observers;
use App\Article;

class ArticleObserver
{
	public function saving(Article $article)
	{
		$article->content = bin2hex($article->content);
	}

	public function retrieved(Article $article)
	{
		// if(strlen($article->content)%2==1 || preg_replace('/[a-zA-Z0-9]+/','',$article->content)!='')
		// return;
		try{
			$article->content = hex2bin(trim($article->content));
		}
		catch (\Exception $e) {
			return;
		} 
	}
}

/app/Providers/ArticleModelServiceProvider.php

<?php

namespace App\Providers;
use Illuminate\Support\ServiceProvider;

class ArticleModelServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        \App\Article::observe(\App\Observers\ArticleObserver::class);
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

Hi @robinhoo1973, I'm out of the country at the moment, I will take a look. In the mean while, can you paste the code for your observer here as well? Thanks!

Yes, I just updated my issue report with the observer code included. Thanks for your prompt response.

Thanks! I will have to create a test for observers. Give me a few weeks. If you would like to take a stab at submitting a PR with a new unit test or even an update to the functionality, that would be great! :)

Take your time and enjoy your trip, it's not urgent case. :)

@robinhoo1973 I created a test for observers and do not see an issue with using observers. It works as expected. Please provide the complete query that you are running.
