我有三个表:产品、公司、类型。公司和类型与产品具有一对多的关系。[型号型号]
class Type extends BaseModel {
public static $table = "type";
public static $timestamps = true;
public function products() {
return $this->has_many('Products');
}
}
[公司型号]
class Company extends BaseModel {
public static $table = "company";
public static $timestamps = true;
public function products() {
return $this->has_many('Products');
}
}
[产品型号]
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');
}
}
在 add_product 路线我有
$product = new Products($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);
但是当我尝试将数据插入数据库时,我得到:
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '11' for key 'PRIMARY'
如何更新 Products 表中的 type_id 和 company_id?
