flush morphToMany not working

[hen3b182]

Project.php

class Project extends Model
{	
    use Rememberable;

    public $rememberCacheTag = 'project_queries';
    public $rememberFor = 60*60*24;
	
    public function users()
    {
        return $this->morphToMany(User::class, 'model','model_has_users');
    }

User.php

class User extends Authenticatable
    {
        use Rememberable;
    
        public $rememberCacheTag = 'user_queries';
        public $rememberFor = 60*60*24;
        
    public function projects()
    {
        return $this->hasMany(Project::class);
    }

Now this works:

Cache::flush();

And this does not:

Project::flushCache('project_queries');

Project::find(1)->name (refreshed) Project::find(1)->users (not refreshed)

help!?

Wouldn't you want to flush the user_queries cache in this instance?

There's some known issues regarding caching with morph relationships. Happy to review any code that seeks to resolve the problems.

Do I have to flush both cache tags in this case? And all other morph relations?

Yeah, I'd assume so. But there are a few open issues around morphing relationships, so no guarantees this will work as you expect.
