Laravel : Doesn't have a default value - KeyProduct with Faker - php

Question

I can't add a keyproduct when i'm creating a new product.
I get the error SQLSTATE[HY000]: General error: 1364 Field 'category_id' doesn't have a default value (SQL: insert into `products` (`activation_key`, `updated_at`, `created_at`) values (57394cd3-54f8-3e95-a951-e11f029fa0f5, 2020-05-27 17:09:08, 2020-05-27 17:09:08))
I don't know why, it asks me that.
What I tried :
category_id is my first column that i'm adding in my table. If I put ->nullable() to category_id , I get the same error with name that is the next column in my table.
This is imy code :
ProductController
public function store(Request $request)
{
$inputs = $request->except('_token');
$quantity = $inputs['quantity'];
factory(KeyProduct::class, $quantity)->create();
foreach ($inputs as $key => $value) {
$home->$key = $value;
}
$home->image=$path;
$home->save();
return redirect('admin/gamelist');
}
Product_table
Schema::create('products', function (Blueprint $table) {
$table->increments('id');
$table->integer('category_id')->unsigned();
$table->string('name');
$table->string('image')->nullable();
$table->string('activation_key')->nullable();
$table->timestamps();
});
KeyProduct_table.php
Schema::create('key_products', function (Blueprint $table) {
$table->increments('id');
$table->string('activation_key');
$table->timestamps();
});
Keyproduct.php
public function products()
{
return $this->HasOne('App\Product')->withPivot('quantity');
}
Product.php
class Product extends Model
{
public function categories()
{
return $this->belongsTo('App\Category', 'category_id');
}
public function keyProduct()
{
return $this->HasOne('App\KeyProduct');
}
protected $fillable = ['quantity'];
}
KeyProductFactory.php
use App\KeyProduct;
use App\Product;
$factory->define(KeyProduct::class, function (Faker $faker) {
$product = factory(Product::class)->create();
return [
'activation_key' => $product->activation_key,
];
});
ProductFactory.php
use App\Product;
use Faker\Generator as Faker;
$factory->define(Product::class, function (Faker $faker) {
return [
'activation_key' => $faker->uuid
];
});
CategoryFactory
use App\Category;
use Faker\Generator as Faker;
$factory->define(Category::class, function (Faker $faker) {
return [
'activation_key' => $faker->uuid
];
});
Thanks for your help.

Answer 1

It fails because the product is created without you setting that category_id or name at the time of creation. Make them nullable() or change your creation method accordingly.

Answer 2

In your SQL you provided values for "activation_key", "updated_at" and "created_at" columns only, so other fields must satisfy at least one statement:
have an AUTO_INCREMENT option;
have a DEFAULT value;
allow NULL values.
You haven't provided enough data to complete the query.

Answer 3

Add more $fillables to your Product.php Model. By looking at your migrations it should look like this:
protected $fillable = [
'category_id', 'name', 'image', 'activation_key', 'quantity'
];
