我正在使用mysql数据库。我有两个具有一对多关系的表模式（客户机和产品模型）。

Schema::create('clients', function (Blueprint $table) {
        $table->id();
        $table->string('name');
        $table->string('job');
        $table->timestamps();
    });

Schema::create('products', function (Blueprint $table) {
        $table->id();
        $table->foreignId('client_id')->constrained();
        $table->string('productName')->unique();
        $table->integer('quantity');
        $table->float('unitPrice');
        $table->timestamps();
    });

我还尝试使用下面的语法，而不是

` $table->foreignId('client_id')->constrained();`

但我也犯了同样的错误。

`$table->unsignedBigInteger('client_id');
 $table->foreign('client_id')->references('id')->on('clients');`

错误如下：

SQLSTATE[HY000]: General error: 1005 Can't create table `product`.`products` (errno: 150 "Foreign key constraint is incorrectly formed") (SQL: 
alter table `products` add constraint `products_client_id_foreign` foreign key (`client_id`) references `clients` (`id`))
