Laravel 5.8：错误字段没有默认值

Question

我看到了类似的问题，但没有一个对我有用。这是Transition 模型

class Transition extends Model
{
 protected $fillable = ['origin_x', 'origin_y', 'destination_x', 'destination_y', 'freight_id', 'status', 'receiver_name', 'receiver_mobile', 'receiver_address'];
 protected $table = 'freight_transitions';
}

这是插入代码

    $transition = Transition::create([
        'origin_x' => $redis['origin_x'],
        'origin_y' => $redis['origin_y'],
        'destination_x' => $redis['destination_x'],
        'destination_y' => $redis['destination_y'],
        'freight_id' => $freight->id,
        'status' => 2,
        'receiver_name' => $redis['receiver_name'],
        'receiver_mobile' => $redis['receiver_mobile'],
        'receiver_address' => $redis['receiver_address']
    ]);

我确信 $redis` 的数组是有价值的。但这是错误

一般错误：1364 字段“origin_x”没有默认值（SQL：插入到freight_transitions（updated_at，created_at）值（2019-11-02 16:42:58，2019- 11-02 16:42:58))

据我所知，Laravel 不会尝试将 origin_x 和其他字段插入数据库。它只插入created_at 和updated_at。我有一个类似的模型，称为Freight，在这段代码上方的几行中，我以相同的方式插入记录，没有错误。但我不知道为什么它只插入created_at和updated_at。

我也试过

$transition = new Transition([....]);//array of above data
$transition->save();

它也会产生同样的错误。

这是迁移

    Schema::create('freight_transitions', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('origin_x');
        $table->string('origin_y');
        $table->string('destination_x');
        $table->string('destination_y');
        $table->string('receiver_name')->nullable();
        $table->string('receiver_mobile')->nullable();
        $table->string('receiver_address')->nullable();
        $table->bigInteger('freight_id')->unsigned();
        $table->foreign('freight_id')->references('id')->on('freight_freights')->onDelete('cascade');
        $table->enum('status', ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14'])->default(1);//1: start
        $table->timestamps();
    });

这是redis json 格式的数组

{
"origin_x": "555",
"origin_y": "666",
"destination_x": "777",
"destination_y": "8888",
"freight_type_id": "1",
"title": null,
"description": null,
"price": 130000,
"features": "2",
"services": "2,5",
"vehicle_id": 1,
"token": "111111",
"payment_type": "3",
"user_id": 1,
"receiver_name": null,
"receiver_mobile": null,
"receiver_address": null,
"payment_status": 1,
"status": 2
}

提前致谢。

Answer 1

我尝试如下插入数据

    $transition = new Transition;
    $transition ->origin_x = $redis['origin_x'];
    $transition ->origin_y = $redis['origin_y'];
    $transition ->destination_x = $redis['destination_x'];
    $transition ->destination_y = $redis['destination_y'];
    $transition ->freight_id = $freight->id;
    $transition ->status = 2;
    $transition ->receiver_name = $redis['receiver_name'];
    $transition ->receiver_mobile = $redis['receiver_mobile'];
    $transition ->receiver_address = $redis['receiver_address'];
    $transition->save();

即使它有效，但对我来说仍然是一个问题，为什么我用于大量项目的代码在这里不起作用：|

如果没有使用 php 的 json_decode 函数将其转换为数组，您是否将 json 转换为数组，然后再试一次。如果可能，然后为您的列提供默认值。
