【问题描述】：

我在尝试注册新用户时收到此错误：“部门 ID 必须是整数”。我收到的所有答案都很有帮助，只是我有时会感到困惑。因此，我添加了更多代码以进行澄清。我已经争吵了几个小时了。这是迁移文件。

                        Schema::create('departments', function (Blueprint $table) 
                        $table->bigIncrements('department_id');
                        $table->integer('department_name');
                        $table->integer('department_code')->unique();
                        $table->text('department_discription')->nullable();
                        $table->tinyInteger('department_status')->default(1);
                        $table->softDeletes();
                        $table->timestamps();
        

这是部门控制器代码

【问题讨论】：

$table->bigIncrements('id'); 或 $table->id(); 自动递增 UNSIGNED BIGINT（主键）等效列。

验证似乎失败了

请提供导致错误的代码、注册、用户模型和迁移

【参考方案1】：

在您的迁移中，尝试将 'department_id' 设为主键 declaratively：

 $table->primary('department_id');

然后（就像评论中的 sta 所说）在您的部门模型中：

 protected $primaryKey = "department_id";

或将其名称更改为“id”

【参考方案2】：

你应该像这样创建一个部门：

\App\Models\Department::create([
       'department_name' => 1,
       'department_code' => 1,
       'department_discription' => 'first department',
       'department_status' => 1
   ]);

不要忘记将列名添加到部门模型中的可填充变量

【讨论】：

这里是部门模型 public $fillable = [ 'department_name', 'department_code', 'department_discription', 'department_status'

department_id 列是“自动增量”，您是否为此分配了任何值？为了更清楚，请完整分享您的代码。

【参考方案3】：

如果我理解您的问题，您将需要更改数据库中的 department_id 字段。 创建一个新的迁移并为您的 department_id 键设置它。

$table->unsignedBigInteger('department_id')->autoIncrement();

这应该可以解决您的问题。它会做的是在您需要添加关系的情况下维护数据库的完整性，因为它将创建与其他表上的 id 相同类型的字段 (unsignedBigInteger)，但它也会自动增加该字段。
