orm with relation data where in laravel eloquent code example

Example 1: whereHas site:https://laravel.com/docs/

use Illuminate\Database\Eloquent\Builder;

// Retrieve posts with at least one comment containing words like code%...
$posts = Post::whereHas('comments', function (Builder $query) {
    $query->where('content', 'like', 'code%');
})->get();

// Retrieve posts with at least ten comments containing words like code%...
$posts = Post::whereHas('comments', function (Builder $query) {
    $query->where('content', 'like', 'code%');
}, '>=', 10)->get();

Example 2: laravel model::query

// Eloquent's Model::query() returns the query builder

Model::where()->get();
// Is the same as 
Model::query()->where()->get();

Model::query();
// Can be useful to add query conditions based on certain requirements
