能言善辩“whereDate” Laravel 5.4升级后不能正常工作

Question

（事先说一句抱歉的长期职位）

我从laravel 5.2升级我的应用程序，以5.4的过程，因为这一直停留在这个问题上早上。出于某种原因，我的查询选择即将到来的商业事件与Eloquent'whereDate'没有返回任何东西，即使其他所有事情都指向它应该工作的事实！

我有一个phpUnit测试，不会通过尝试和本地化的问题。 （见下文）

我有一个 '业务' 模式：

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class Business extends Model 
{ 
    protected $table = 'businesses'; 
    .. 

public function businessEvents(){ 
    return $this->hasMany('App\BusinessEvent', 'business_id'); 
} 

除了作为一个 'BusinessEvent' 模式：

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class BusinessEvent extends Model 
{ 
    protected $table = 'business_events'; 
    protected $fillable = ['business_id', ..., 'start_date', 'end_date']; 

    public function business(){ 
     return $this->belongsTo('App\Business', 'business_id'); 
    } 
... 

这两者我做哑在我的测试版本。伪“业务”适用于其他测试，但我介绍了这个测试用例下面假人business_event'：

protected function createMockBusinessEventWithUpcomingDateTime($businessId){ 
    $faker = Faker::create(); 

    $businessEvent = BusinessEvent::create([ 
     'business_id' => $businessId, 
     'name'   => $faker->name, 
     'description' => $faker->text, 
     'start_date' => date("Y-m-d H:i:s", strtotime(date("Y-m-d H:i:s")."+30 minutes")), 
     'end_date'  => date("Y-m-d H:i:s", strtotime(date("Y-m-d H:i:s")."+1 hour +30 minutes")) 
    ]); 

    ... 

    $business = Business::find($businessId); 
    if($business){ 
    $businessEvent->business()->associate($business); 
    } 

    return $businessEvent; 
} 

现在，这里是真正的测试功能：

public function testGetUpcomingN(){ 

    $this->businessEvent = $this->createMockBusinessEventWithUpcomingDateTime($this->business->id); 

    $response = $this->json('GET', '/api/v1/business/'.$this->business->id.'/events/upcoming/2'); 

    $this->outp($response->content()); 

    $this->outp("Testing Assertions"); 
    $this->assertEquals(200, $response->status()); 
    $this->assertEquals($this->business->businessEvents()->first()->id, $this->businessEvent->id);  
} 

测试不会失败，这意味着该事件正确地与业务关联，并且无论我如何查询api端点（HttpRequester，记录结果，测试中的返回值，生产...），它总是返回一个空的阵！

的以下功能就是所谓的控制器（也验证了！）：

public function upcomingN($businessId, $n){ 
    Log::info('Get upcoming '.$n.' recorded events for business with id: '.$businessId); 
    $business = Business::find($businessId); 
    if (is_null($business)){ 
     Log::warning('No business exists with given id. Exiting.'); 
     return response('No Content.', 204); 
    } 

    $currentDate = date('Y-m-d H:i:s'); 

    $greaterThan = $business->businessEvents()->first()->end_date >= $currentDate; 
    Log::info("Greater THAN:", [$greaterThan]); 

    $events = $business->businessEvents()->whereDate('end_date', '>=', $currentDate)->take($n)->get(); 

    if (!is_null($events)){ 
     Log::info('Got upcoming N recorded events for business with id: '.$businessId, (array) $events); 
     return response()->json($events); 
    } 

    return response('No Content.', 204); 
} 

正如你所看到的，我甚至尝试登录了“$大于”布尔值，应该测试完全相同的“whereDate”所做的事情，它的计算结果为true！我已经尝试了Carbon :: parse（） - ing，设置语言环境，现在我几乎没有想法。

的老功能，在5.2的工作：

public function upcomingN($businessId, $n){ 
    Log::info('Get upcoming N recorded events for business with id: '.$businessId); 
$business = Business::find($businessId); 
if (is_null($business)){ 
    Log::warning('No business exists with given id. Exiting.'); 
     return response('No Content.', 204); 
    } 

    $currentDate = date('Y-m-d H:i:s'); 
    $events = $business->businessEvents()->whereDate('start_date', '>=', $currentDate)->take($n)->get(); 

    if (!is_null($events)){ 
     Log::info('Got upcoming N recorded events for business with id: '.$businessId, (array) $events); 
     return response()->json($events); 
    } 

    return response('No Content.', 204); 
} 

有一件事我也有在升级过程中的变化是使用mysql-DB设置为不严格，因为Laravel在抱怨缺乏默认值。但是，我检查了数据库并且测试条目正确填充。

任何帮助将不胜感激！

感谢这么多Omisakin Oluwatobi，该解决方案是用雄辩的事实“其中”而不是“whereDate”，为“whereDate”只比较日期，而不是日期时间（事后看来这在明显）。

如果您可以使用相同数量的代码实现与'where'相同的结果，我觉得'whereDate'函数存在有点令人困惑。

我可以验证（单元测试），下面的最终解决方案适用于未来的选择和日期时间过去忽略的：

public function upcomingN($businessId, $n){ 
    Log::info('Get upcoming '.$n.' recorded events for business with id: '.$businessId); 
    $business = Business::find($businessId); 

    if (is_null($business)){ 
     Log::warning('No business exists with given id. Exiting.'); 
     return response('No Content.', 204); 
    } 

    $currentDate = date('Y-m-d H:i:s'); 
    $events = $business->businessEvents()->where('end_date', '>=', $currentDate)->take($n)->get(); 

    if (!is_null($events)){ 
     Log::info('Got upcoming N recorded events for business with id: '.$businessId, (array) $events); 
     return response()->json($events); 
    } 

    return response('No Content.', 204); 
}
