mysql - Laravel 5.5 - 迁移不起作用

Question

我正在尝试运行在 Laravel 5.2 版本上完美运行的迁移，但是当我尝试在 Laravel 5.5 上运行它时，出现错误:

In Connection.php line 664:

SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'to_date' (SQL: create table transactions (id
int unsigned not null auto_increment primary key, user_id int unsigned not null, vehicle_id int unsigned not null, from_date t
imestamp not null, to_date timestamp not null, flight_number varchar(255) not null, created_at timestamp null, updated_at ti
mestamp null) default character set utf8mb4 collate utf8mb4_unicode_ci)

In Connection.php line 458: SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'to_date'

这是该表的迁移:

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateTransactionsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('transactions', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('user_id')->unsigned();
            $table->foreign('user_id')->references('id')->on('users');
            $table->integer('vehicle_id')->unsigned();
            $table->foreign('vehicle_id')->references('id')->on('vehicles');
            $table->timestamp('from_date');
            $table->timestamp('to_date');
            $table->string('flight_number');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('transactions');
    }
}

为什么在 5.2 上运行时不能在新版本的 laravel 上运行？

Answer 1

我找到了导致问题的原因，在 laravel 5.5 中 MySQL 在 laravel config 中启用了严格模式 database.php 文件默认情况下，通过将模式设置为 'strict' => false，就像在 5.3 版本中一样，我可以运行迁移。
