I have two models that have a HasMany relationship pointing to each other (through a pivot table). Let's call them Post and Category.
Since I don't want any Posts to exist without at least one Category, I want to create a Category for it in its factory, using something like this in the Post factory.
public function configure() {
return $this->afterCreating(function (Post $post) {
$post->categories()->attach(Category::factory()->create());
});
}
However, in a seeder, I might already have a Category that I want to use with a new Post. So I also want the option to pass in a Category into the Post factory, and not create a new Category, but instead attach the one given.
If this was a simple BelongsTo, it would be easy, but how do I do this with a HasMany?
I hope I described this right.
Thank you!
public function configure() {
return $this->afterCreating(function (Post $post, $attributes) {
$category = $attributes['category'] ?? Category::factory()->create();
$post->categories()->attach($category);
});
}
If you pass a category here it will be attached, otherwise it will create a new one.
$category = Category::find(1);
Post::factory()->create(['category' => $category]);
