Question

我正在尝试使用Yajra数据表从数据透视表中检索数据。

模型Project.php

class Project extends Model
{
    protected $fillable = ['id','client_id', 'name','description', 'projectType','service_id','files','startDate','endDate','progress','status'];

    public function employee()
    {
        return $this->belongsToMany('App\Employee');
    }
}

模型Employee.php

class Employee extends Model
{
    protected $fillable = ['id', 'name', 'surname','address','tel', 'email','profession'];

    public function project()
    {
        return $this->belongsToMany('App\Project');
    }
}

模型EmployeeProject.php

class EmployeeProject extends Pivot
{
    protected $fillable = ['id', 'employee_id', 'project_id'];
}

ProjectsController.php

$projects = Project::with('employee');
return Datatables::of($projects)
->make(true);

projects.blade.php

$('#datatable').DataTable({
                "processing": true,
                "serverSide": true,
                "paging":   false,
                "ajax": "{{ route('projects.getdata') }}",
                "order": [[1,'desc']],
                "columns": [    
                {"data": "id"},     
                {"data": "client_id"},
                {"data": "name"},
                {"data": "description"},
                {"data": "projectType"},
                {"data": "service_id"},               
                {"data": "employees.name"}, - **I need to retrieve the names of the employees who are involved in the project**
                {"data": "files"},
                {"data": "startDate"},
                {"data": "endDate"},
                {"data": "progress", orderable:false, searchable: false},
                {"data": "status"},

让您知道我正在使用数据透视表employee_project链接表（员工和项目）。创建功能运行良好，因为记录已正确添加到数据透视表中。问题是我需要将所有参与该项目的员工的姓名涂上去，例如：

id| name | employeeName  |...|
-----------------------------
1 | test | John, Mark,...|...|

谢谢。

尝试这样的事情：

在projects.blade.php

{
  data: function (row) {
   let employeeNames= [];
     $(row.employee).each(function (i, e) {
       employeeNames.push(e.name);
       });
     return employeeNames.join(", ")
   }, name: 'employee.name'
},
