Custom filtering data

If all I have is this:

    public function searchByCategory(Post $post, Category $category)
    {   
        $post = Post::where('category_id', $category->id)
                    ->latest('id')
                    ->paginate(8);
        $category = Category::get();
        return view('posts.category', ['posts' => $post, 'category' => $category]);
    }

And im using it to see all posts regarding a category, would it be wise to create a controller just for this? I was using it inside my PostsController but I don't want it to be mixed with the CRUD essentials.. This works though, I don't think it's the most advanced thing ever and I dont neccesarily need it but im mainly looking for suggestions :-)

I mean, when I say it's not the most advanced thing ever is because you look at the data through an <a href=""> anchor tag element:

            <span> Category: </span>
                <a href="{{ route('posts.category', $post->category) }}"> 
                    {{ $post->category->name }} 
                </a>
