【问题描述】：

我收到错误 1364。字段“dis”没有默认值。我在表单和 CRUD 操作方面进展顺利。通过表单将数据保存在数据库中时，出现此错误。创建表单重定向以显示视图。单击表单的提交按钮时出现此错误。我检查我的数据库数据没有存储在那里。

错误：

Illuminate\Database\QueryException
SQLSTATE[HY000]: General error: 1364 Field 'dis' doesn't have a default value (SQL: insert into 
`students` (`full_name`, `dob`, `gender`, `cnic`, `marital_Status`, `nationality`, `religion`, 
`domicile`, `province`, `father_name`, `father_cnic`, `father_profession`, `guardian_name`, 
`guardian_cnic`, `email`, `address`, `tel_landline`, `tel_office`, `cell1`, `cell2`,

`fsc_total_marks`, `fsc_marksheet_image`, `nmdcat_obtained_marks`, `nmdcat_total_marks`, 
 `nmdcat_result_image`, `updated_at`,

这是我的控制器

     return view ('index');

这是我的迁移：

public function up()

    Schema::create('students', function (Blueprint $table) 
        $table->id();
        $table->string('full_name');
        $table->date('dob');
        $table->text('gender');
        $table->text('dis');

        $table->text('province');

        $table->integer('matric_total_marks');
        $table->binary('matric_marksheet_image');

        $table->timestamps();
    );

【问题讨论】：

存储功能没有$student->dis = $request->dis

我收到错误 1364。字段 'dis' 没有默认值。 这意味着 (1) 字段 'dis' 没有默认值，并且在同时定义为 NOT NULL (2) 您尝试使用查询插入新行，其中 dis 列根本没有被提及。最简单的解决方案是根据ALTER TABLE执行并为该列指定默认值。

你尝试过什么调试问题？

【参考方案1】：

您没有将任何数据保存到数据库中的 dis 字段，而是 dis 输入字段将数据保存到数据库中的性别字段。这样做

$student->dis=$request->dis;

或为数据库中的 dis 字段分配一些默认值。

【讨论】：

或添加迁移文件。 $table->text('dis')->nullable();//$table->text('dis')->default('value');

【参考方案2】：

在您的表中，此处的 dis 列不可为空。因此，当您保存任何行时，此列需要填充。要解决此问题，您需要将此列设为空或为此设置默认值。添加一个新的迁移文件并使该列可以为空或设置默认值。

$table->text('dis')->nullable();

或

$table->text('dis')->default('your_disere_value');

或者将dis列值从刀片保存到控制器。

$student->dis=$request->dis;
