我正在与一个破碎的工匠打交道。每次我运行任何迁移命令时，它都会说：

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

无论我是否删除项目表和模型，它都无法再次运行迁移命令。我已经在用户和项目之间创建了一个关系，一个用户可以有很多项目，自从引入它之后，我的整个应用程序似乎都坏了。像Auth::check()给出同样的错误。

项目模型：

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

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

用户型号：

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');
    }

用户迁移文件：

<?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');
}

我希望其他人也经历过这种情况，并且可以帮助我。

另一个注意事项：我重命名了由工匠创建的控制器。不确定这是否有任何影响。作曲家是否转储自动加载以确保..

更新：

即使在完全删除所有模型和完整数据库之后，错误仍然存​​在。我什至回滚到今天下午工作的代码，没有今晚的变化。所以我的猜测是整个安装有问题..

最终，不仅回滚了应用程序代码，我还从一个工作副本中回滚了供应商 laravel 代码，这起到了作用。奇怪的是，供应商目录可能会被破坏。
