如何在Laravel写播种机

Question

我有表格可标记，它是多对多多元关系（标签和帖子）的表格：

taggable_id - id of Post
tag_id - id of Tag
taggable type - location of post model (default value"App/Models/Posts/Post")
is_search_term - boolen (0 or 1)

如何创建每次为关系创建相同记录的播种机？

Answer 1

如果db_id设置为主键，则db_id将自动创建，taggable_id将从Tag模型中获取值。

你可以尝试这样的事情;

$factory->define(App\Tag::class, function (Faker\Generator $faker) {
    return [
        'taggable_id' => random_int(\DB::table('posts')->min('id'), \DB::table('posts')->max('id')),
        'is_search_term'=>$faker->numberBetween(0,1),
'taggable_type'=>$faker->sentence(2),

    ];
});
