如何在Laravel

Question

我有表可加標籤寫播種機，它的表多對多多態關係（標籤和後）：

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) 

如何創建，每個時間關係創建相同記錄的播種機？

Answer 1

如果Tag_id設置爲主鍵，tag_id將由db自動創建，taggable_id可以從Tag模型獲取值。

你可以嘗試這樣的事情;

$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), 

    ]; 
});
