用于合并 laravel 中的三个表的连接查询

Question

我想根据 department_string_id 加入部门 table 的项目 table 并加入项目 table 和 project_owner_id 的用户 table用户 table 条件 project.project_owner_id=users.aceid

desired query (working fine)
 select p.*,d.department_head_aceid from project as p inner join department as d on p.department_string_id=d.department_string_id inner join users as u on p.project_owner_id=u.aceid where u.id='4'

Laravel查询

 $approver_id_roles=DB::table('project')
         ->join('department', 'project.department_string_id', '=', 'department.department_string_id')->join('users','project.project_owner_id','=','users.aceid')
         ->where('project.project_owner_id','=','users.aceid')
         ->select('department.department_head_aceid')->get();

发现以下错误

TokenMismatchException in VerifyCsrfToken.php line 68:

我这里做错了什么

Answer 1

为了避免 CSRF 攻击，我们希望在表单中添加令牌。 Laravel token

<input type="hidden" name="_token" value="{{ csrf_token() }}">
