1. 建立表結構

a.

命令： php artisan make:migration create_posts_table

2.生產檔案

<?php

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

class CreatePostsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     
 
*/
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->increments('id');
            $table->string('title', 120)->default("");
            $table->text('content');
            $table->integer('user_id')->default(0);
            
 
$table->timestamps();
        });
    }

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

3. 當自定義完表屬性後，生成表

命令： php artisan migrate

注意：如果是laravel5.4 會報錯

解決方案：

a.修改檔案：app\Providers\AppServiceProvider.php

b.　  use Illuminate\Support\Facades\Schema;

c.      Schema::defaultStringcLength(191);
