Laravel快速开发后端API数据迁移

Laravel数据迁移

生成数据迁移
php artisan make:migration create_tests_table
新的迁移文件会被放置在 database/migrations 目录中。每个迁移文件的名称都包含了一个时间戳，以便让 Laravel 确认迁移的顺序
生成的迁移文件如下所示

<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateLaravelTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('laravel', function (Blueprint $table) {
            $table->string('emaileee')->index();
            $table->string('tokenee');
            $table->timestamp('created_ateee')->nullable();
        });
    }

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

运行迁移
php artisan migrate

修改表结构
修改迁移文件，运行命令 php artisan migrate:refresh
代码如下所示

class CreateTestTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('test', function (Blueprint $table) {
            $table->increments('id');
            $table->string('email')->unique();
            $table->string('name');
            $table->string('testalter');//表新增加字段
            $table->string('testSuccess');//表新增加字段
            $table->timestamps();
        });
    }

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