此查询有效并返回我想要的结果,但是一旦变成集合或尝试"分页",它将返回一个空结果。我尝试对一个简单的DB::table('users')->paginate(5)[0]
进行分页,它可以工作,所以我想它不是来自分页本身。
法典
$photographers_available = Photographer::where('is_photographer', '=', '1')
->where(function($q)use($city_id)
{
$q->whereHas('studioAddress', function($q)use($city_id)
{
$q->where('city_id', '=', $city_id);
})
->orWhereHas('user', function($q)use($city_id) // TK could reduce to 'user.address' I think
{
$q->whereHas('address', function($q)use($city_id)
{
$q->where('city_id', '=', $city_id);
});
});
})
->whereHas('stypesPhotographer', function($q)use($stype)
{
$q->where('shooting_type_id', '=', $stype);
})
->whereHas('availabilities', function ($q) use ($selected_date_time)
{
$q->where('unavailable_start_date', '<', $selected_date_time)
->where('unavailable_end_date', '>', $selected_date_time);
}, '=', 0)
->whereHas('bookings', function($q)use($selected_date_time)
{
$q->where('booking_date', '=', $selected_date_time);
}, '=', 0)
->join('stypes_4_photographer', function($join)use($stype)
{
$join->on('photographer_id', '=', 'photographers.id')
->where('shooting_type_id', '=', $stype);
});
$photobla = $photographers_available->first();
echo '<pre>';print_r($photobla);
// RETURNS RESULTS CORRECTLY
$photoTEST = $photographers_available->get();
echo '<pre>';print_r($photoTEST);die();
// RETURNS $photoTEST as NULL.....
// WHY has $photographers_available BEEN EMPTIED?????
结果
// $photobla result
Photographer Object
(
[fillable:protected] => Array
(
[0] => id
[1] => is_photographer
[2] => service_description
[3] => radius_around_city_available
[4] => tax_nbr
[5] => user_id
[6] => average_score
)
[table:protected] => photographers
[touches:protected] => Array
(
[0] => stypesPhotographer
)
[connection:protected] =>
[primaryKey:protected] => id
[perPage:protected] => 15
[incrementing] => 1
[timestamps] => 1
[attributes:protected] => Array
(
[id] => 677
[is_photographer] => 1
[ETC>>>>>>>>]
)
[original:protected] => Array
(
[id] => 677
[is_photographer] => 1
[ETC>>>>>>>>]
)
[relations:protected] => Array

[hidden:protected] => Array

[visible:protected] => Array

[appends:protected] => Array

[guarded:protected] => Array

[dates:protected] => Array

[observables:protected] => Array
(

[with:protected] => Array
(
)
[morphClass:protected] =>
[exists] => 1
)
// THE $photoTEST result:
Illuminate'Database'Eloquent'Collection Object
(
[items:protected] => Array
(
)
)
所以你可以看到$photographers_available
在->first()
后刚刚被清空了.最重要的是,即使在初始查询中直接使用,分页也不起作用。
$photographers_available; // it is a query, consider other name
$photographers_available->first();
// set limit 1 on the query and return it's result
$photographers_available->get();
// returns the query result (remember limit 1 above..)
$photographers_available->paginate();
// return the query result paginated (ignoring limit 1 above)
我建议你这样做(没有这个first
调用):
dd($photographers_available->get());
或者return
这个东西,而不是echo whataver
,因为这不是办法。在控制器中输出类似内容会中断应用流。
