Php artisan迁移已断开：未定义的属性

我在和一个破碎的工匠打交道。每次我运行任何migrate命令时，它都会显示：

  [ErrorException]
  Undefined property: Illuminate\Database\Query\Builder::$projects

无论我是否删除projects表和model，它都无法再次运行migrate命令。我已经在一个用户和一个项目之间建立了一种关系，一个用户可以有很多项目，自从引入这个关系以来，我的整个应用程序似乎都坏了。像Auth:：check这样的东西也会出现同样的错误

项目模型：

class Projects extends Eloquent {
    public function user() {
        return $this->belongsTo("User");
    }

    public function android_app_entries() {
        return $this->hasMany("AndroidAppEntries");
    }
}

用户模型：

class User extends Eloquent implements UserInterface, RemindableInterface {

    use UserTrait, RemindableTrait;

    protected $table = 'users';

    public static $rules = array(
        'username'=>'required|between:6,18',
        'password'=>'required|between:6,18',
        'project_id'=>'required'
    );

    // Artist __has_many__ projects
    public function projects()
    {
        return $this->hasMany('Projects');
    }

项目迁移文件：

<?php

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

class CreateProjectsTable extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('projects', function($table) {
            $table->increments('id');
            $table->string('project_name');
            $table->string('client_name');
            $table->integer('users_id');
            $table->foreign('users_id')->references('id')->on('users');
            $table->timestamps();
        });



    }

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

<?php

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

class CreateUsersTable extends Migration {

/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::create('users', function($table){
        $table->increments('id');
        $table->string('username');
        $table->string('password', 64);
        $table->string('role');
        $table->string('remember_token');
        $table->timestamps();
    });
}

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

最终，在回滚应用程序代码之后，我还从一个工作副本中回滚了供应商的laravel代码，这就成功了。奇怪的是，供应商目录可能会被破坏。

您还有其他迁移吗？或者你也跑的播种机？该错误意味着您在某个不具有该属性的对象上访问->项目。您可能认为这是您的模型，并尝试访问关系是的，我进行了一些其他迁移，但自从我添加了关系后，关系就中断了。与任何项目相关的种子也将被移除。最后，有趣的是，如果我在->项目上搜索整个项目，就不会有结果。。似乎是缓存问题或其他什么如果删除关系会怎么样？没有结果，删除了所有与项目有关的内容。看起来它的缓存速度非常快。真让我沮丧。因为我可能需要重新创建一个新的应用程序或其他东西..请查看您的日志app/storage/logs/laravel.log，看看是否可以从中找出错误的来源。。。
