小编vio*_*ium的帖子

我有界面:

interface AbstractMapper
{
    public function objectToArray(ActiveRecordBase $object);
}

和课程:

class ActiveRecordBase
{
   ...
}

class Product extends ActiveRecordBase
{
   ...
}

========

但我不能这样做:

interface ExactMapper implements AbstractMapper
{
    public function objectToArray(Product $object);
}

或这个:

interface ExactMapper extends AbstractMapper
{
    public function objectToArray(Product $object);
}

我有错误" 声明必须兼容 "

那么,有没有办法在PHP中执行此操作？

在我的 rails 应用程序中，我决定使用单例来创建某种工厂来正确获取对象。

配置/初始化程序/registry.rb：

registry = Registry.instance

registry.define_lazy :period_predictor do
  PeriodPredictor.new(NotificationBuilder.new, 28, 4, 3)
end

registry.define_lazy :notification_sender do
  NotificationSender.new
end

库/registry.rb：

# Registry class which is singleton and stores values.
class Registry
  include Singleton


  # Define simple value. Like a constant.
  #
  # @param key [Symbol]
  # @param value
  def define(key, value)
    container[key] = value
  end


  # Define value (block required) which will be calculated when it will be need.
  # It will calculate it every time when it will …

我在Laravel 4中测试控制器时遇到问题.

我有下一个代码:

public function getRemind()
{
    $status = \Session::get('status');
    $error = \Session::get('error');
    $email = \Session::get('email');

    return \View::make('admin/reminds/remind_form', compact('status', 'error', 'email'));
}

我想测试控制器在视图中传递的正确数据:

public function testGetRemind()
{
    \Session::set('status', 'status');
    \Session::set('error', 'error');
    \Session::set('email', 'email');
    $response = $this->action('GET', 'Admin\RemindersController@getRemind');
    $this->assertTrue($response->isOk(), 'Get remind action is not ok');
    $this->assertViewHas('status', 'status');
    $this->assertViewHas('error', 'error');
    $this->assertViewHas('email', 'email');
}

但这不起作用.

另外我不能模拟Session-class,因为框架不允许 - 当我尝试这样做时会有很多错误.
