Laravel - Data mismatch from eager load - php

Question

I am creating factories and saving the page model to the film model so its film to page one-to-many,
i've followed the docs but when im trying to save the models to each other i am getting this error
General error: 20 datatype mismatch (SQL: insert into "pages" ("id", "page_url", "film_id", "updated_at", "created_at") values (591d61cb-3090-3945-b920-ba797245cb97, http://larson.com/, bd3bab38-f8be-4674-ae5d-15e8f6b6172a, 2019-11-15 11:23:02, 2019-11-15 11:23:02))
These are the classes i am working with
Film migration
public function up()
{
Schema::create('films', function (Blueprint $table) {
$table->uuid('id')->primary();
$table->string('name');
$table->string('description');
$table->timestamps();
});
}
Pages migration
public function up()
{
Schema::create('pages', function (Blueprint $table) {
$table->bigIncrements('id');
$table->uuid('film_id')->nullable();
$table->string('page_url')->nullable();
$table->timestamps();
});
}
PagesFactory
$factory->define(Pages::class, function (Faker $faker) {
return [
'id' => $faker->uuid,
'page_url' => $faker->url,
'film_id' => factory(\App\Models\Film::class)->create()->id
];
Pages model
public function film(): BelongsTo
{
return $this->belongsTo(Film::class);
}
FilmController
*/
public function show(string $id)
{
$film = Film::with([
'pages',
'languages',
'categories',
])->findOrFail($id);
return $film;
FilmControllerTest
public function getFilmTest()
{
$film = factory(Film::class)->create();
$language = Language::where('id', 'en')->where('name', 'English')->first();
$categories = Category::where('main-cat', 'Science')->where('sub-cat', 'Fiction')->first();
$film->pages()->save(factory(Page::class)->create());
$film->languages()->attach($language->id);
$film->categories()->attach($categories->id);
$response = $this->json('GET', '/film/' . $film->id)
->assertStatus(200);
$response
->assertJson(['id' => $guestProfile->id])
->assertJson(['name' => $film->description])
->assertJson(['languages' => $film->languages->toArray()])
->assertJson(['categories' => $film->categories->toArray()])
}
when i comment out this line from the test it works fine $film->pages()->save(factory(Page::class)->create());
im abit lost on why im having this issue trying to save the models so the pages becomes part of the response... can i get some help/example please :D

Answer 1

The id of your pages table is set to a bigIncrements (UNSIGNED BIGINT), but in your PagesFactory you are trying to store a uuid.
$factory->define(Pages::class, function (Faker $faker) {
return [
'id' => $faker->uuid,
'page_url' => $faker->url,
'film_id' => factory(\App\Models\Film::class)->create()->id
];
Remove 'id' => $faker->uuid, from the factory, you don't have to set an auto incrementing field.
Another option (depending on the design you have in mind) is to change the migration of the pages table and set the id column to $table->uuid('id')->primary();

Answer 2

try using the make() method, as in:
$film->pages()->save(factory(Page::class)->make());
