错误 - SQLSTATE [23000]：完整性约束违规：1452无法添加或更新子行：外键约束失败（`assign_project`，CONSTRAINT`assign_project_ibfk_2` FOREIGN KEY（`assigned_to`）REFERENCES`user`（` user_id`））（SQL：插入`assign_project`（`project_id`，`description`，`work_start_date`，`work_end_date`，`assign_status`，`assigned_by`，`assigned_to`）值（1，xyz，2016-09 -02,2016-11-02,1,1，））

用户模型

<?php
 namespace App;
 use Illuminate\Database\Eloquent\Model;

 class User extends Model
 {

  protected $fillable = ["user_id","company_id","first_name","last_name","email","password","confirm_password","phone_number","address","pincode","role_id","user_status"]; 

 }
?>

控制器中的

public function getassignprojectemployee(Request $Request){

  $data = Request::all();
    $input = DB::table('usi_assign_project')
    ->insert($data);

    if($input > 0){
        return Redirect::to('admin_assign_projects_employee');
    }
    else
    {
        return Redirect::to('admin_assign_project');
    }
 }
