如何在多对多关系中正确检索laravel中的数据？

Question

I have a many to many relationship with a pivot table.

goods

id | title | ...

tags

id | title | ...

good_tag

id | good_id | tag_id | ...

How correctly retrieve all goods and their tags in laravel?

Thanks

Answer 1

With Eager Loading

$goods = Good::with('tags')->get();

foreach ($goods as $good) {
    // each goods
    echo $good->title;

    foreach ($good->tags as $tag) {
        // each tag for that goods
        echo $tag->title;
    }
}

Each returned Good model will have its collection of Tags attached.
