我试图创建一个报告页面，显示从特定日期到特定日期的报告。这是我当前的代码:
$now = date('Y-m-d');
$reservations = Reservation::where('reservation_from', $now)->get();
这在普通SQL中所做的是从表中选择*，其中reservation_from = $now。
我在这里有这个问题，但我不知道如何将其转换为雄辩的问题。
SELECT * FROM table WHERE reservation_from BETWEEN '$from' AND '$to
如何将上面的代码转换为雄辩的查询?
当前回答
我已经创建了模型作用域
要了解更多关于范围的信息，请查看以下链接:
laravel.com/docs/eloquent # query-scopes medium.com/@janaksan / using-scope-with-laravel
代码:
/**
* Scope a query to only include the last n days records
*
* @param \Illuminate\Database\Eloquent\Builder $query
* @return \Illuminate\Database\Eloquent\Builder
*/
public function scopeWhereDateBetween($query,$fieldName,$fromDate,$todate)
{
return $query->whereDate($fieldName,'>=',$fromDate)->whereDate($fieldName,'<=',$todate);
}
在控制器中，将Carbon Library添加到顶部
use Carbon\Carbon;
从现在开始获取最近十天的记录
$lastTenDaysRecord = ModelName::whereDateBetween('created_at',(new Carbon)->subDays(10)->startOfDay()->toDateString(),(new Carbon)->now()->endOfDay()->toDateString() )->get();
从现在开始获取过去30天的记录
$lastThirtyDaysRecord = ModelName::whereDateBetween('created_at',(new Carbon)->subDays(30)->startOfDay()->toDateString(),(new Carbon)->now()->endOfDay()->toDateString() )->get();
其他回答
whereBetween方法验证列的值是否在between之间 两个值。
$from = date('2018-01-01');
$to = date('2018-05-02');
Reservation::whereBetween('reservation_from', [$from, $to])->get();
在某些情况下，需要动态添加日期范围。根据@Anovative的评论，你可以这样做:
Reservation::all()->filter(function($item) {
if (Carbon::now()->between($item->from, $item->to)) {
return $item;
}
});
如果你想添加更多的条件，那么你可以使用orWhereBetween。如果你想要排除一个日期间隔，那么你可以使用whereNotBetween。
Reservation::whereBetween('reservation_from', [$from1, $to1])
->orWhereBetween('reservation_to', [$from2, $to2])
->whereNotBetween('reservation_to', [$from3, $to3])
->get();
其他有用的where子句:whereNotIn, whereenull, whereNotNull, whereDate, whereMonth, whereDay, whereYear, whereTime, whereColumn, whereExists, whereRaw。
Laravel关于Where子句的文档。
如果你的字段是datetime而不是date(尽管它适用于这两种情况):
$fromDate = "2016-10-01";
$toDate = "2016-10-31";
$reservations = Reservation::whereRaw(
"(reservation_from >= ? AND reservation_from <= ?)",
[
$fromDate ." 00:00:00",
$toDate ." 23:59:59"
]
)->get();
另一种方法:
use Illuminate\Support\Facades\DB;
$trans_from = date('2022-10-08');
$trans_to = date('2022-10-12');
$filter_transactions = DB::table('table_name_here')->whereBetween('created_at', [$trans_from, $trans_to])->get();

以下方法应该有效:
$now = date('Y-m-d');
$reservations = Reservation::where('reservation_from', '>=', $now)
->where('reservation_from', '<=', $to)
->get();
