所以我在 Laravel 8 和 Vue 3 中有一个项目。在我的 StudentComponent 上，我有一个创建学生的表单，我有一个 vue-select 下拉菜单，当我点击它时，我可以填写我的输入字段：
在同一个组件上，我还有一个 Card/ 表，在其中我有输入字段和单选输入，当我选择我的学生时，我想自动填充它们：
Progression Axis 列上的输入字段的内容在一个表上，而评估列上的单选按钮在另一个表上，让我向您展示我的数据库：
所以你可以看到我已经从我的用户表中检索了数据，但我想从这个用户那里获得进展，然后是标准，然后是主题。我已经尝试了一些 SQL 请求，它可以包含所有内容但没有成功。
让我给你看我的代码：`public function getTrainees() { $sessionName = Session::get('sessionName');
return DB::table('progressions')
->select(DB::raw("users.*, GROUP_CONCAT(progressions.id SEPARATOR ', ') as ids,
GROUP_CONCAT(progressions.axis SEPARATOR ', ') as axes,
GROUP_CONCAT(progressions.topic_id SEPARATOR ', ') as topic_ids"))
->leftjoin('topics','topics.id','=','progressions.topic_id')
->leftjoin('criteria','criteria.id',"=","topics.criteria_id")
->leftjoin('cards','cards.id','=','criteria.card_id')
->leftjoin('users','users.id','=','cards.user_id')
->where('cards.session','LIKE',$sessionName)
->groupBy(['users.id','users.lastname','users.firstname'])
->get();
}`
这是我在控制器中的请求，但是有了这个请求，我为用户提供了所有进展，但我无法正确使用它。
这是我的 StudentComponent ：
//I retrieve my request with this method in my student component
getTrainee() {
axios.get(AXIOS + 'trainee')
.then(response => this.trainees = response.data)
.catch(error => console.log(error));
},
//And this is my data you could need on this component
data() {
return {
trainees: [],
selectedStudent: [],
},<!--This is the vueSelect element + the form where I create/Retrive the data of my student using vue-select-->
