Illuminate \ Database \ QueryException (42P01) SQLSTATE[42P01]: Undefined table: 7 ERROR: relationship "suggesteds" does not exist LINE 1

Question

我试图使用此处的代码在 laravel 中创建迁移。但不幸的是，它会弹出一个像这里给出的错误。

我使用 PostgreSQL 9.2.24

<?php

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

class CreateSuggestedsTable extends Migration
{
/**
 * Run the migrations.
 *
 * @return void
 */
 public function up()
 {
    Schema::create('suggesteds', function (Blueprint $table) {
        $table->increments('id');
        $table->integer('channel_id')->unsigned()->index();
        $table->string('group')->nullable()->index(); // 'technology', 
    'lifestyle', etc.
        $table->string('language')->default('en')->index();
        $table->integer('z_index')->default(0);
        $table->timestamps();
    });
    }

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

在我使用 MySQL 之前并没有它的错误。 任何帮助将不胜感激。

Answer 1

请使用：

php artisan migrate:refresh

Answer 2

从数据库中手动删除suggesteds 表（如果存在），然后再次运行迁移脚本。

你也应该检查这个issue

Answer 3

你可以试试：

<?php

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

class CreateSuggestedsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('suggesteds', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('channel_id')->unsigned()->index();
            $table->string('group')->nullable()->index();
            $table->string('language')->default('en')->index();
            $table->integer('z_index')->default(0);
            $table->timestamps();
        });
    }

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