SQLSTATE [42S02]：找不到基表或视图：1146

Question

I'm trying to login as Administrator. I used Multiple authentication one for my User that works fine and second for Admin that I'm trying to login but when I insert right values in my database which I manually inserted the values using Seeding it gives me a error which I don't know the cause.

What I did is I configure my auth.php So I can have two authentications for User and Admin.

<?php

return [



'defaults' => [
    'guard' => 'web',
    'passwords' => 'users',
],



'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

    'api' => [
        'driver' => 'token',
        'provider' => 'users',
    ],

    'admins' => [
        'driver'   => 'session',
        'provider' => 'admins'
    ]
],



'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => App\Models\User::class,
    ],

     // For admin
    'admins' => [
        'driver' => 'eloquent',
        'model' => App\Models\Admin::class
    ]

    // 'users' => [
    //     'driver' => 'database',
    //     'table' => 'users',
    // ],
],



'passwords' => [
    'users' => [
        'provider' => 'users',
        'email' => 'auth.emails.password',
        'table' => 'password_resets',
        'expire' => 60,
    ],

    'admins' => [
        'provider' => 'admins',
        'email' => 'auth.emails.password',
        'table' => 'password_resets',
        'expire' => 60,
    ],
],

];

create_admins_table - Migrations

<?php

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateAdminsTable extends Migration
{
/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::create('admins', function (Blueprint $table)
    {
        $table->increments('id');
        $table->string('username');
        $table->string('password');
        $table->timestamps();
    });
}
}

My migration files are set. So I migrated it.

Admin - Models

<?php

namespace App\Models;

use Illuminate\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;

class Admin extends Model implements AuthenticatableContract
{
use Authenticatable;


protected $guard = "admins";

protected $table = 'admins';

protected $fillable = [
    'username',
    'password',
];

protected $hidden = [
    'password',
    'remember_token'
];
}

AdminTableSeeder - Seeds

<?php

use Illuminate\Database\Seeder;

class AdminTableSeeder extends Seeder
{
public function run()
{
    DB::table('admins')->delete();

    $admins = array(
    array('username' => 'admin',
          'password' => Hash::make('admin'))
    );

    DB::table('admins')->insert($admins);
}
}

AdminController - Controllers

<?php

namespace App\Http\Controllers;

use Auth;
use App\Models\Admin;
use Illuminate\Http\Request;

class AdminController extends Controller
{
public function postAdminLogin(Request $request)
{
    $this->validate($request, 
    [
        'username' => 'required',
        'password' => 'required|min:7',
    ]);

    if(!Auth::attempt($request->only(['username','password']), $request->has('remember')))
    {
        dd('error');
    }

    dd('Succesful!');
}
}

UPDATE!!

So I changed my username and password to letmein to avoid my confusion. I attempt to login the right values but I can't still login. !Auth:attempt won't match my values in my database and prints me a "error" message.

public function postAdminLogin(Request $request)
{
    $this->validate($request, 
    [
        'username' => 'required',
        'password' => 'required|min:7',
    ]);

    if(!Auth::attempt($request->only(['username','password']), $request->has('remember')))
    {
        dd('error');
    }

    dd('Succesful!');
}

admin.blade.php

<form class = "form-vertical" role = "form" method = "post" action = "{{ route ('auth.admin') }}">

            <div class = "form-group {{ $errors->has('username') ? 'has-errors' : '' }}">

                @endif
            </div>

            <div class = "form-group {{ $errors->has('password') ? 'has-errors' : '' }}">

                @endif

            <div class = "checkbox">
                <label>
                    <input type = "checkbox" name = "remember">Remember me</input>
                </label>

            <div class = "form-group">

            </div>

            <input type = "hidden" name = "_token" value = "{{ Session::token() }}">

        </form>

Answer 1

Your Table name is in Question here... We think it should have been "admins" in the AdminTableSeeder like so:

        use Illuminate\Database\Seeder;

        class AdminTableSeeder extends Seeder {

            public function run() {
                DB::table('admins')->delete();  //<== "admins" AS DEFINED IN YOUR CONFIG::: NOT "admin"

                $admin = array(
                array('username' => 'admin',       
                      'password' => Hash::make('admin'))
                );

                DB::table('admins')->insert($admin);
            }
        }

Answer 2

AdminTableSeeder - Seeds

Use truncate instead of delete

use Illuminate\Database\Seeder;

class AdminTableSeeder extends Seeder
{
public function run()
{
  DB::table('admins')->truncate();

  $admins = array(
  array('username' => 'admin',
        'password' => Hash::make('admin'))
  );

  DB::table('admins')->insert($admins);
 }
 }

Answer 3

The SQL query next to the error message says

select count(*) as aggregate from `admin` where `password`=admin

Now, in your WHERE clause password is backticked, so I assume it is a column(not a table). Backticks are usually used in SQL for table names or column names. But the you compare the column name to admin, without ticks. 'admin' is not a reserved word, and it is not quoted in your query as a text string should be, so the database server then starts looking for a table with that name to match.

So, have you tried adding quotes there?

SELECT COUNT(*) AS aggregate FROM `admin` WHERE `password`='admin'

Edit:

If all else fails you might also want to simply dump the database queries being issued. Add a listener/dump:

\DB::listen(function($sql, $bindings, $time) {
    var_dump($sql);
    var_dump($bindings);
    var_dump($time);
});

..and check the output.
