Question

我正在使用Laravel 5.1。但我无法查询数据库：

我只是这样做：User :: all（）;在我的UserController上

这是错误：

这是我的用户模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    //
}

这是我的UserController

<?php

namespace App\Http\Controllers;

use App\User;
use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;

class UserController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {
        $users = User::all();
        // return view('users.index', compact('users'));
        return $users;
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  Request  $request
     * @return Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  Request  $request
     * @param  int  $id
     * @return Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return Response
     */
    public function destroy($id)
    {
        //
    }
}

这是我的postgres SQL代码

DROP TABLE IF EXISTS users CASCADE;

CREATE TABLE users
(
   id              serial         NOT NULL,
   code            varchar(255),
   login           varchar(50)     NOT NULL,
   name            varchar(255)    NOT NULL,
   email           varchar(255)    NOT NULL,
   password        varchar(60)     NOT NULL,
   remember_token  varchar(100),
   created_at      timestamp       NOT NULL,
   updated_at      timestamp       NOT NULL
);

-- Column id is associated with sequence public.users_id_seq

ALTER TABLE users
   ADD CONSTRAINT users_pkey
   PRIMARY KEY (id);

COMMIT;

出了什么问题？请帮忙。有没有我错过的配置文件？

Answer 1

阅读此itertools.chain.from_iterable后，我决定创建扩展默认模型类的模型，并用自定义代码替换getDateFormat。因为改变供应商目录中的类是个坏主意。

我希望它有所帮助：

class FixedModel extends Illuminate\Database\Eloquent\Model {
    public function getDateFormat()
    {
        return 'Y-m-d H:i:s.u';
    }
}

class User extends FixedModel {}

Answer 2

您应该在模型类中声明$dateFormat：

protected $dateFormat = 'Y-m-d H:i:s.u';

Laravel 5.1无法识别postgres中的时间戳字段
