Inserting data with one-to-many relationship - php

Question

I have three tables: Products, Company, Type. Company and Types has one-to-many relationship with Products.
[type model]
class Type extends BaseModel {
public static $table = "type";
public static $timestamps = true;
public function products() {
return $this->has_many('Products');
}
}
[company model]
class Company extends BaseModel {
public static $table = "company";
public static $timestamps = true;
public function products() {
return $this->has_many('Products');
}
}
[products model]
class Products extends BaseModel {
public static $table = 'products';
public static $timestamps = true;
public function company() {
return $this->belongs_to('Company');
}
public function type() {
return $this->belongs_to('Type');
}
}
In add_product route i have
$product = new Products($new_product);
$company_id = $all_posts['company_id'];
$company = Company::find($company_id);
$company->products()->save($product);
$type_id = $all_posts['type'];
$type = Type::find($type_id);
$type->products()->save($product);
but when I try to insert data to db i get:
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '11' for key 'PRIMARY'
How do I update both type_id and company_id in Products table?

Answer 1

If I am not wrong, your products table should have product_id and type_id columns ? Just specify these values:
$new_product['company_id'] = $all_posts['company_id'];
$new_product['type_id'] = $all_posts['type'];
$product = new Products($new_product);
$product->save();
You don't need to use Company and Type model to make relationship between them and a product. You can simply fill the ids.
