How to ignore specific Mailable class in Laravel Telescope?

Question

I have Telescope installed on Laravel 10. The register() method in the TelescopeServiceProvider.php currently contains:

Telescope::filter(function (IncomingEntry $entry) {
    if ($this->app->environment('local')) {
        return true;
    }

    return $entry->isReportableException() ||
        $entry->isFailedRequest() ||
        $entry->isScheduledTask() ||
        $entry->hasMonitoredTag() ||
        $entry->isSlowQuery() ||
        $entry->isClientRequest() ||
        ($entry->type === EntryType::REQUEST && in_array('slow', $entry->tags)) ||
        ($entry->type === EntryType::GATE && $entry->content['result'] !== 'allowed') ||
        $entry->type === EntryType::LOG ||
        $entry->type === EntryType::JOB ||
        $entry->type === EntryType::EVENT ||
        $entry->type === EntryType::COMMAND ||
        ($entry->type === EntryType::MAIL && $entry->content['mailable'] !== 'App\Mail\Communication\CommunicationMailable');
});

As you can see from the last couple of lines, I'm trying to log every Mailable except the CommunicationMailable class. I'm currently doing it by a string comparison using the mailable property set by Telescope, but I don't really like it because if I changed the path of the mailable class I would have to remember to change the string manually each time. Isn't there a better way?

Answer 1

The mailable property set by Telescope corresponds to the fully-qualified class name, so you can use the ::class constant to get it programmatically (PHP docs). In my case:

1. Import the CommunicationMailable class in TelescopeServiceProvider.php:

use App\Mail\Communication\CommunicationMailable;

2. Use the ::class constant instead of the string written manually (from the code in the question):

($entry->type === EntryType::MAIL && $entry->content['mailable'] !== CommunicationMailable::class)
