cacheFor(0) would cache forever?

[flycoo]

$Test = Test::cacheFor(0)->where('ip', '127.0.0.1')->first();

as the code above. when I delete my record from db, the $Test remain would be retreive and it's not null

According to the source, caching forever can be done by using

    /**
     * Indicate that the query results should be cached forever.
     *
     * @return \Illuminate\Database\Query\Builder|static
     */
    public function cacheForever()
    {
        return $this->cacheFor(-1);
    }
