一次播种多行laravel 5

Question

我目前正在尝试为我的用户表播种。如果我用 2 行这样尝试，它会失败。如果我只使用单个数组而不是 $users 数组中的 2 个数组来创建一些假数据，它就可以正常工作。

我做错了什么，正确的方法是什么？

class UserTableSeeder extends Seeder {

    public function run()
    {
        DB::table('users')->delete();

        $users = [
            ['id' => 1, 'name' => 'Stephan de Vries', 'username' => 'stephan', 'email' => 'stephan-v@gmail.com', 'password' => bcrypt('carrotz124')],
            ['id' => 2, 'name' => 'John doe', 'username' => 'johnny', 'email' => 'johndoe@gmail.com', 'password' => bcrypt('carrotz1243')],
        ];

        User::create($users);
    }

}

Answer 1

如果你必须使用模型，你需要一个循环：

foreach($users as $user){
    User::create($user);
}

否则你可以只使用DB::table()和insert：

DB::table('users')->insert($users);

其实你也可以在模型上调用insert()（结果查询是一样的）

User::insert($users);

注意如果您选择 insert 方法，您将失去特殊的 Eloquent 功能，例如时间戳和模型事件。

这适用于 Laravel ^5

<?php

use Illuminate\Database\Seeder;

class UsersTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */

    public function run()
    {
        // check if table users is empty
        if(DB::table('users')->count() == 0){

            DB::table('users')->insert([

                [
                    'name' => 'Administrator',
                    'email' => 'admin@app.com',
                    'password' => bcrypt('password'),
                    'created_at' => date('Y-m-d H:i:s'),
                    'updated_at' => date('Y-m-d H:i:s'),
                ],
                [
                    'name' => 'Agency',
                    'email' => 'agency@app.com',
                    'password' => bcrypt('password'),
                    'created_at' => date('Y-m-d H:i:s'),
                    'updated_at' => date('Y-m-d H:i:s'),
                ],
                [
                    'name' => 'End',
                    'email' => 'endcustomer@app.com',
                    'password' => bcrypt('password'),
                    'created_at' => date('Y-m-d H:i:s'),
                    'updated_at' => date('Y-m-d H:i:s'),
                ]

            ]);
            
        } else { echo "\e[31mTable is not empty, therefore NOT "; }

    }
}

Answer 3

public function run()
{
    //
    for ($i=0; $i < 1000; $i++) { 
         DB::table('seo_contents')->insert([
            'title' => str_random(10),
            'content' => str_random(100),
            'created_at'=>date('Y-m-d H:i:s'),
            'updated_at'=>date('Y-m-d H:i:s'),

        ]);
    }

}

Answer 4

create() 仅用于存储一条记录。要存储多条记录，您应该使用insert() 而不是create()。 所以代码将如下所示：

class UserTableSeeder extends Seeder {

  public function run()
  {
    DB::table('users')->delete();

    $users = [
        ['id' => 1, 'name' => 'Stephan de Vries', 'username' => 'stephan', 'email' => 'stephan-v@gmail.com', 'password' => bcrypt('carrotz124')],
        ['id' => 2, 'name' => 'John doe', 'username' => 'johnny', 'email' => 'johndoe@gmail.com', 'password' => bcrypt('carrotz1243')],
    ];

    User::insert($users);
  }

}

附： insert() 函数不会存储时间戳。即created_by & updated_by 字段。

Answer 5

如果有人为此苦苦挣扎，我自 Laravel 5 以来一直在使用以下内容，并且可以确认仍在 Laravel 7+ 中工作...

class UserTableSeeder extends Seeder {

public function run()
{
    \DB::table('users')->delete();

    \DB::table('users')->insert(array (
        0 => 
          array (
                 'id' => 1,
                 'name' => 'Stephan de Vries',
                 'username' => 'stephan',
                 'email' => 'stephan-v@gmail.com',
                 'password' => bcrypt('carrotz124'
         ),
        1 => 
          array (
                 'id' => 2,
                 'name' => 'John doe',
                 'username' => 'johnny',
                 'email' => 'johndoe@gmail.com',
                 'password' => bcrypt('carrotz1243'
         ),
     ));

}}

使用截断

<?php

use Illuminate\Database\Seeder;
use App\User;

class UsersTableSeeder extends Seeder
{
     /**
     * Run the database seeds.
     *
     * @return void
     */

  public function run()
    {

      User::truncate();

        $users =  [
            [
              'name' => 'Super Admin',
              'email' => 'superadmin@gmail.com',
              'password' => '123456',
            ],
            [
              'name' => 'Account Admin',
              'email' => 'accountadmin@gmail.com',
              'password' => '13456',
            ],
            [
              'name' => 'Project Admin',
              'email' => 'projectadmin@gmail.com',
              'password' => '13456',
            ],
            [
              'name' => 'Client Admin',
              'email' => 'clientadmin@gmail.com',
              'password' => '13456',
            ]
          ];

          User::create($users);

    }
}
