Sorting userlist in Laravel - php

Question

I am very beginner in Laravel.
I have Laravel 5.8 in my project.
I have this code:
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->char('enable', 1)->default(0);
$table->string('name', 120)->nullable();
$table->string('surname', 120)->nullable();
$table->string('email', 120)->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
........
$table->rememberToken();
$table->timestamps();
$table->engine = "InnoDB";
$table->charset = 'utf8mb4';
$table->collation = 'utf8mb4_unicode_ci';
});
Schema::create('comments', function (Blueprint $table) {
$table->bigIncrements('id');
$table->bigInteger('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
$table->string('commentable_type');
$table->bigInteger('commentable_id');
$table->char('enable', 1)->default(0);
$table->char('to_stats', 1)->default(0);
$table->tinyInteger('rating')->default(0); // 1-5
$table->text('content');
$table->dateTime('date_time');
$table->ipAddress('ip');
$table->engine = "InnoDB";
$table->charset = 'utf8mb4';
$table->collation = 'utf8mb4_unicode_ci';
How can I show users list:
sort after number of comments held
sort after number of votes which user has (comments-> rating)?

Answer 1

Try this
//User model
public function comments()
{
return $this->hasMany('App\Comment');
}
public function usersSortedByCommentCount()
{
$users = User::with('comments')->get()->sortBy(function($user)
{
return $user->comments->count();
});
return $users;
}
public function usersSortedByRating()
{
return User::whereHas('comments', function ($q) {
$q->orderBy('rating', 'desc');
})->get();
}

Answer 2

$users_sorted_by_comments = User::with('comments')->get()->sortBy(function($user){
return $user->comments->count();
})
The other condition is quite similar, you need to load ratings on comments and then just sort by that count like this:
$users_sorted_by_ratings_on_comments = User::with('comments')->get()->sortBy(function($user){
return $user->comments->reduce(function($carry, $comment) {
return $carry + $comment->rating;
}, 0 );
})
Laravel Collection reduce
