npm -v 6.4.1 nvm --version 0.33.11

当我安装laravel-echo(在ubuntu16.04中)

npm i --save socket.io-client

我收到了错误警告

@foreach ($searchalls as $searchall)

     @if($i == 1 )

                <p>
                     <a class="btn" href="#">View details »</a>
                </p>
       </div>

我在刀片上得到的结果是

1 =1%3
1 =2%3
1 =3%3
1 =4%3

不能得到数字余数？

我该如何解决这个问题？

   $search_alls=
    DB::table('a16s as A')
    ->select('A.id')
    // ->select('A.*')
    ->addSelect(DB::raw('SUM(CASE WHEN B.approve = 1 ELSE 0 END) as Yshow'))
    ->leftjoin('a16s_likes as B', function($join) {
        $join->on('A.id', '=', 'B.p_id');
        })
    ->groupBy('A.id')
    ->get();

当我使用上面的 select('A.id') 时效果很好。

但是当我使用 select('A.*') 选择所有 A 列时，出现错误

SQLSTATE[42000]: Syntax error or access violation: 1055 'employee.A.name' isn't in GROUP BY 

PS：employee是我的数据库名称A表上的列是

id name ....
1  john
2  mary
3  susan

如何通过 leftjoin 选择所有列？A.id 列与 B.p_id 列是一对多关系。

当我使用php artisan db：seed时出现错误？在UserFactory.php第27行中：

Type error: Argument 1 passed to
Illuminate\Database\Eloquent\Factory::{closure}() must be an instance
of Faker\Generator\Generator, instance of Faker\Generator given

Userfactory.php 使用Faker \ Generator作为Faker；

（这是第27行）

$factory->define(App\Models\Admin::class, function (Faker\Generator $faker) {
    static $password;

        return [
            'name' => $faker->name,
            'email' => $faker->safeEmail,
            'password' => $password ?: $password = bcrypt('secret'),
            'remember_token' => str_random(10),
        ];
    });

AdminsTableSeeder.php

public function run()
{
    factory('App\Models\Admin',3)->create([
        'password' => bcrypt('123456')
        ]);
}

DatabaseSeeder.php

public function run()
{
    // $this->call(UsersTableSeeder::class);
    $this->call(AdminsTableSeeder::class);
}

我不知道怎么回事。
