去掉json响应中的数字(LARAVEL 8)
我在控制器中的功能在下面
public function getStudentsinGrade($grade, $school_id){
$students = Student::where('school_id', $school_id)->get();
$this -> grade = $grade;
$gradeStudent= $students->filter(function($value,$key){
return $value->grade == $this->grade;
});
if(count($gradeStudent) > 0){
return response()->json($gradeStudent);
}
else{
return response('No Registered Student');
}
}下面是我得到的回应
*{
"2": <---this number here is the problem and it appeared when get API response
{
"id": 14,
"student_name": "Polly Grain",
"gender": "Female",
"stream_id": 1,
"school_id": 1,
"final_year_id": 2,
"grade": "Form Four"
},
"3": {
"id": 15,
"student_name": "Polly Grain",
"gender": "Male",
"stream_id": 3,
"school_id": 1,
"final_year_id": 2,
"grade": "Form Four"}
}*我想要得到的回应是
{ "id"：1，"student_name"："sae sddat"，“性别”：“男性”，"stream_id"：2，"school_id"：10，"final_year_id"：12，"Form 1“}，{ "id"：1，"student_name"："sae sddat"，”性别“：”男性“，"stream_id"：2，"school_id"：10，"final_year_id"：12，“年级”："Form One“}，{ "id"：1，"student_name"："sae sddat"，”性别“：”男性“，"stream_id"：2，"school_id"：10，"final_year_id"：12，”student_name“："Form One”}

要解决这个问题，首先将集合转换为数组，然后使用array_values()函数消除那些困扰您的烦人的数组键。然后，将其转换回集合，并将其作为json响应传递。代码：
public function getStudentsinGrade($grade, $school_id){
$students = Student::where('school_id', $school_id)->get();
$this -> grade = $grade;
$gradeStudent= $students->filter(function($value,$key){
return $value->grade == $this->grade;
});
if(count($gradeStudent) > 0){
$gradeStudent = collect(array_values($gradeStudent->toArray()));
return response()->json($gradeStudent);
}
else{
return response('No Registered Student');
}
}现在，这将给出如下所需的结果：
{
"id": 14,
"student_name": "Polly Grain",
"gender": "Female",
"stream_id": 1,
"school_id": 1,
"final_year_id": 2,
"grade": "Form Four"
},
{
"id": 15,
"student_name": "Polly Grain",
"gender": "Male",
"stream_id": 3,
"school_id": 1,
"final_year_id": 2,
"grade": "Form Four"}

为什么不向查询中添加额外的where子句
public function getStudentsinGrade($grade, $school_id){
$students = Student::where('school_id', $school_id)
->where('grade', $grade)
->get();
if($students->count() > 0){
return response()->json($gradeStudent);
}
else{
return response('No Registered Student');
}
