Php Laravel访问器和;透视表上的变数

我的模型中有多对多关系,我想在透视表中使用访问器和变异器,但它似乎不起作用

用户模型

public function roles()
{
    return $this->belongsToMany(Role::class,UserRole::class)
        ->withPivot('faculty_id', 'status');
}
用户角色模型

public function getRoleIdAttribute($role) {
    if($role == 1) {
        return "admin";
    } else if($role == 2){
        return "teacher";
    } else if($role == 3){
        return "student";
    }
    return null;
}

public function setRoleIdAttribute($role)
{
    if($role == 'admin') {
        $this->attributes['role_id'] = 1;
    } else if($role == 'teacher') {
        $this->attributes['role_id'] = 2;
    } else if($role == 'student') {
        $this->attributes['role_id'] = 3;
    }
}
在我的控制器中,我使用

$user =  User::create([
        'first_name' => $request->first_name,
        'middle_name' => $request->middle_name,
        'last_name' => $request->last_name,
        'email' => $request->email,
        'password' => Hash::make($request->password)
    ]);
$user->roles()->attach('teacher', ['faculty_id' => $faculty]);

我可以使用accessor和Mutators将'teacher'更改为2吗?

belongstomy()的第二个参数用于表名,而不是自定义透视模型。改用

您还需要将
role\u id
添加到
withPivot
调用:

public function roles()
{
    return $this->belongsToMany(Role::class)->using(UserRole::class)
        ->withPivot('faculty_id', 'status', 'role_id');
}
