show last post from each category

Question

I have two models Post and Category

// migration post

public function up()
{
    Schema::create(\'posts\', function (Blueprint $table) {
        $ta         


        

Answer 1

An Eloquent solution for loading categories with latest post is to create an additional hasOne() relationship in the Category model:

public function latestPost()
{
    return $this->hasOne(Post::class)->latest();
}

And then use eager loading:

Category::with('latestPost')->get();

This will generate just 2 queries to DB.
