保存id后,Laravel Eloquent变为0

Question

这是从https://github.com/lucadegasperi/oauth2-server-laravel迁移的表

在表中oauth_clients,id的字段数据类型是varchar(40),而不是int.

$name = Input::get('name');
$id = str_random(40);
$secret = str_random(40);

$client = new oauthClient;
$client->name = $name;
$client->id = $id;
$client->secret = $secret;
$client->save();

保存后(); $ client-> id变为'0',而不是我指定的字符串.

这使得以下关系表保存失败.

$endpoint = new OauthClientEndpoint(array('redirect_uri' => Input::get('redirect_uri));
$client->OauthClientEndpoint()->save($endpoint);

我检查了$client->id:保存后,它变为0,我得到一个错误,包括这个:

(SQL: insert into `oauth_client_endpoints` (`redirect_uri`, `client_id`, `updated_at`, `created_at`) values (http://www.xxxxx.com, 0, 2014-09-01 11:10:16, 2014-09-01 11:10:16))

我手动保存了一个端点以防止此错误.但是我该如何解决这个问题呢？

这是我的模特:

class OauthClient extends Eloquent {

  protected $table = 'oauth_clients';

  public function OauthClientEndpoint(){
    return $this->hasOne('OauthClientEndpoint', 'client_id', 'id');
  }

}

class OauthClientEndpoint extends Eloquent {

  protected $table = 'oauth_client_endpoints';
  protected $fillable = array('redirect_uri');

  public function OauthClient(){
    return $this->belongsTo('OauthClient', 'client_id', 'id');
  }

}

class CreateOauthClientsTable extends Migration {
  public function up() {
    Schema::create('oauth_clients', function (Blueprint $table) {
      $table->string('id', 40);
      $table->string('secret', 40);
      $table->string('name');
      $table->timestamps();

      $table->unique('id');
      $table->unique(array('id', 'secret'));
    });
  }

  public function down() {
    Schema::drop('oauth_clients');
  }
}

class CreateOauthClientEndpointsTable extends Migration {
  public function up() {
    Schema::create('oauth_client_endpoints', function (Blueprint $table) {
      $table->increments('id');
      $table->string('client_id', 40);
      $table->string('redirect_uri');

      $table->timestamps();

      $table->foreign('client_id')
        ->references('id')->on('oauth_clients')
        ->onDelete('cascade')
        ->onUpdate('cascade');

    });
  }

  public function down() {
    Schema::table('oauth_client_endpoints', function ($table) {
      $table->dropForeign('oauth_client_endpoints_client_id_foreign');
    });

    Schema::drop('oauth_client_endpoints');
  }
}

当您设置自己的ID而不使用auto_increment时,请务必添加public $incrementing = false;到该模型.在你的情况下你想要:

class OauthClient extends Eloquent {

  public $incrementing = false;
  protected $table = 'oauth_clients';

  public function OauthClientEndpoint(){
    return $this->hasOne('OauthClientEndpoint', 'client_id', 'id');
  }

}

这是巨大的Laravel文档中的一个小红块:

注意:通常,您的Eloquent模型将具有自动递增键.但是,如果要指定自己的键,请将模型的递增属性设置为false.
