Question

我为此项目设置了Homestead的每个项目安装，因此我不会将RethinkDB添加到我的所有Laravel应用程序中。我能够非常轻松地在Homestead中设置RethinkDB，并迁移数据库表，但我似乎无法为它们播种。运行php artisan db:seed会在终端中抛出此错误：

[Symfony\Component\Debug\Exception\FatalThrowableError]
Fatal error: Call to a member function prepare() on null

laravel.log中的错误：

我的种子用户非常典型：

<?php

use Illuminate\Database\Seeder;

class UserTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        // Developer accounts
        factory(App\User::class, 'admin', 1)->create([
            'username' => 'test',
            'email' => 'test@domain.com'
        ]);

        factory(App\User::class, 1)->create();
    }
}

使用简单的模型工厂：

<?php

/**
 * Define a general user factory for seeding the database.
 */
$factory->define(App\User::class, function (Faker\Generator $faker) {
    return [
        'username' => $faker->name,
        'password' => bcrypt(str_random(10)),
        'email' => $faker->email,
        'remember_token' => str_random(10),
    ];
});

/**
 * Define an administrator factory for seeding the database.
 */
$factory->defineAs(App\User::class, 'admin', function (Faker\Generator $faker) use ($factory) {

    // Reuse general user factory attributes
    $user = $factory->raw(App\User::class);

    return array_merge($user, [
        'role' => 'admin'
    ]);
});

更新

看起来它可能是RethinkDB和Laravel之间的问题，但我不确定如何修复它。这是问题发生的方法，我使用monolog注销到Laravel.log，并在日志语句下面包含输出。似乎方法getPdo（）为null。

public function statement（$ query，$ bindings = []） { return $ this-＆gt; run（$ query，$ bindings，function（$ me，$ query，$ bindings）{ if（$ me-＆gt; pretending（））{ 返回true; }

    Log::info($query);
    // insert into "users" ("username", "password", "email", "remember_token", "role", "updated_at", "created_at") values (?, ?, ?, ?, ?, ?, ?)

    $bindings = $me->prepareBindings($bindings);

    Log::info($bindings);
    // array (
    //   0 => 'test',
    //   1 => '$2y$10$8icEztzBbFL/556imvn8D.905i67RrCuUwf6csaN2r75W0s0ifg/a',
    //   2 => 'test@domain.com',
    //   3 => 'WUA1vvpyvQ',
    //   4 => 'admin',
    //   5 => '2016-02-11 03:33:29',
    //   6 => '2016-02-11 03:33:29',
    // )

    Log::info($me->getPdo());
    // null

    return $me->getPdo()->prepare($query)->execute($bindings);
});

}

由于用户模型是使用make：rethink-model通过工匠生成的唯一模型，因此看起来失败了，它引入了使用Illuminate Model类的Authenticatable。要解决此问题，必须手动更新它，方法是删除use Illuminate\Foundation\Auth\User as Authenticatable;，然后将其包含的特征直接应用于用户模型，然后继承自use \duxet\Rethinkdb\Eloquent\Model;，这样您的最终用户类现在看起来就像像这样：

namespace App;

use Illuminate\Auth\Authenticatable;
use \duxet\Rethinkdb\Eloquent\Model;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Foundation\Auth\Access\Authorizable;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;


class User extends Model implements
    AuthenticatableContract,
    AuthorizableContract,
    CanResetPasswordContract
{
    use Authenticatable, Authorizable, CanResetPassword;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}
