Question

我动态地使用MySQL数据库成功地向上一个表添加了一个列，但是当我填写表单运行并将其发送到本地服务器中的数据库时，它显示：

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'forge. posts' doesn't exist (SQL: select count(*) as aggregate from ` posts` where ` slug ` = hihello)

我的迁移代码表＆＃39;帖子＆＃39;

<?php

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');
            $table->text('body');
            $table->timestamps();
        });
    }

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

用于插入名为＆＃39; slug＆＃39;的新列。在＆＃39;帖子＆＃39;表

 <?php

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

class AddSlugToUsers extends Migration
{



    public function up(){

      Schema::table('posts',function(Blueprint $table){
        $table->string('slug')->unique()->after('title');

      });

    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down(){

     Schema::table('posts',function(Blueprint $table){
     $table->dropColumn('slug');
        });


    }
   }

成功插入＆＃39; slug＆＃39;列，但问题是将表单发布到数据库。
