Laravel one to many table seed is not seeded as expected
问题
我有一个类似这样的关系表ERD。我在Laravel中使用Eloquent数据库关系来管理外键。
它运行正常，但是添加的数据跳过了一行。
这是我如何填充数据库的方式。
public function run(): void
{
User::factory()
->has(FavPlant::factory(),'fav_Plant')
->count(5)
->create();
Plants::factory()
->has(FavPlant::factory(),'fav_Plant')
->count(5)
->create();
}
如何使关系表同时具有user_id和plants_id？
英文:
So I have a relationship table like this ERD. I'm using eloquent database relationship in laravel to manage the foreign key.
It worked, but the data added is skipping one row.
This is how I seed the database.
public function run(): void
{
User::factory()
->has(FavPlant::factory(),'fav_Plant')
->count(5)
->create();
Plants::factory()
->has(FavPlant::factory(),'fav_Plant')
->count(5)
->create();
}
How do I make the relation table have both user_id and plants_id simultaneously?

你似乎在用户和植物之间通过 FavPlant 枢纽表建立了多对多的关系。你可以像下面这样同时设置 user_id 和 plant_id。
public function run(): void
{
$users = User::factory()
->count(5)
->create();
$plants = Plant::factory()
->count(5)
->create();
// 使用循环为 FavPlant 枢纽表建立关系
foreach ($users as $user) {
foreach ($plants as $plant) {
FavPlant::factory([
'user_id' => $user->id,
'plant_id' => $plant->id,
])->create();
}
}
}
英文:
You seem to have a many-to-many relationship between users and plants through the FavPlant pivot table. You can set both user_id and plant_id at the same time as below.
public function run(): void
{
$users = User::factory()
->count(5)
->create();
$plants = Plants::factory()
->count(5)
->create();
// Seed FavPlant pivot table with relationships
foreach ($users as $user) {
foreach ($plants as $plant) {
FavPlant::factory([
'user_id' => $user->id,
'plants_id' => $plant->id,
])->create();
}
}
}
