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 '$to
如何将上面的代码转换为雄辩的查询?
当前回答
@masoud，在Laravel，你必须从表单请求字段值。所以,
Reservation::whereBetween('reservation_from',[$request->from,$request->to])->get();
而在livewire中，略有变化
Reservation::whereBetween('reservation_from',[$this->from,$this->to])->get();
其他回答
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();
如果你想检查当前日期是否存在于db中的两个日期之间: =>在这里，如果员工的申请从和到日期在今天存在，则查询将获得申请列表。
$list= (new LeaveApplication())
->whereDate('from','<=', $today)
->whereDate('to','>=', $today)
->get();
我遵循了其他贡献者提供的有价值的解决方案，遇到了一个没有人解决的小问题。如果reservation_from是一个datetime列，那么它可能不会产生预期的结果，并且会错过所有日期相同但时间高于00:00:00时间的记录。为了改进上面的代码，一个小的调整是需要像这样。
$from = Carbon::parse();
$to = Carbon::parse();
$from = Carbon::parse('2018-01-01')->toDateTimeString();
//Include all the results that fall in $to date as well
$to = Carbon::parse('2018-05-02')
->addHours(23)
->addMinutes(59)
->addSeconds(59)
->toDateTimeString();
//Or $to can also be like so
$to = Carbon::parse('2018-05-02')
->addHours(24)
->toDateTimeString();
Reservation::whereBetween('reservation_from', [$from, $to])->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();
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();
