How do I know if the signed in user has "liked" a Post, Url or News?

How do I know if the signed in user has “liked” a Post, Url or News?

I have a morphTo relation between a couple of models both for comments, images and likes. But I haven’t figured out how to use it with likes.

In my Like model, I have the following relation:

    public function likeable()
    {
        return $this->morphTo();
    }

The migration for Like model:

        Schema::create('likes', function (Blueprint $table) {
            $table->id();
            $table->foreignId('user_id')->constrained()->onDelete('cascade');;
            $table->integer('likeable_id');
            $table->integer('likeable_type');
            $table->timestamps();
        });

So far so good I assume - just basic standard docs boilerplate. And for Post, Url and News I have the following relation:

    public function likes()
    {
        return $this->morphOne(Like::class, 'likeable');
    }

In my Livewire ContentComponent I have the following render() method:

    public function render()
    {
        $collection = collect();

        $posts = Post::search('topic', $this->search)->withCount(['comments', 'likes'])->with('user')->latest()->get();
        $urls = Urls::search('topic', $this->search)->withCount(['comments', 'likes'])->with('user')->latest()->get();
        $news = News::search('topic', $this->search)->withCount(['comments', 'likes'])->latest()->get();

        /** Push posts to the collection */
        foreach ($posts as $post) $collection->push($post);
        /** Push urls to the collection */
        foreach ($urls as $item) $collection->push($item);
        /** Push news to the collection */
        foreach ($news as $item) $collection->push($item);

        $collection->each(function ($item, $key) {
            // dd($item);
        });

        return view('livewire.content-component', [
            'urls_news_and_posts' => $collection->sortByDesc('created_at')->sortByDesc('sticky')->paginate(20)
        ]);
    }

This is were I encounter my problem

Im able to count all the likes for each specific model. But somehow I need to be on the frontend know that the user has liked the model. I was trying to add a key to $collection in the render() method, something like (bool) user_as_liked - but here my “programming” skills fail me.

within User Model

public function likes()
{
   return $this->hasMany(Like::class);
}

Laravel will know the user_id column ties back to the auth’d user

now you can use

Auth::user()->likes

to get all the likes for that user, determine your logic to use as needed.
or
User model:

public function liked(Like $like)
    {
       if Auth::user->likes($like) {
          return true
       }
    }

in blade:

@if(Auth::user->liked($item)
