在学生模型中,我已经设置了这样的属性
protected $appends = ['present'];
public function getPresentAttribute(){
return $this->getTotalDays()-$this->getAbsentDays();
}
我的数据库看起来像这样
| id | student_name | created_at |
*----*----------------------*-------------------*--
| 1 | Adam | 2020/11/10 |
| 2 | Annie | 2020/11/10 |
|3 | Paul | 2020/11/10 |
如果我确实喜欢在控制器中这样做
$students=Student::get();
foreach($students as $stu){
echo "<pre>"; print_4($stu->student_name,$stu->present); die;
}
我的结果将是这样
Adam -> 32
Annie ->34
Paul->33
但是我需要这样转换
['Students', 'Present Day',],
['Adam' , 32],
['Annie' , 34],
['Paul' , 33],
所以在控制器中,我尝试这样
public function attendancePerformance(){
$students=Student::get();
$data=[];
$student_data=[];
$arrayHeader = ["Students","Present Day"];
array_push($data,$arrayHeader);
foreach ($students as $stu) {
array_push($student_data, $stu->student_name,$stu->present);
}
array_push($data,$student_data)
}
但是它不起作用。我应该怎么做?
