使用 eloquent ORM 在 Laravel 中批量插入

Question

我们如何使用 Eloquent ORM 在 Laravel 中执行批量数据库插入？

我想在 Laravel 中实现这一点： https://stackoverflow.com/a/10615821/600516但我收到以下错误。

SQLSTATE[HY093]：无效参数号：混合命名和位置参数。

Answer 1

您只需使用Eloquent::insert()。

例如：

$data = array(
    array('name'=>'Coder 1', 'rep'=>'4096'),
    array('name'=>'Coder 2', 'rep'=>'2048'),
    //...
);

Coder::insert($data);

.

Answer 2

我们可以更新 GTF 答案以轻松更新时间戳

$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=>date('Y-m-d H:i:s'),
        'modified_at'=> date('Y-m-d H:i:s')
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=>date('Y-m-d H:i:s'),
         'modified_at'=> date('Y-m-d H:i:s')
       ),
    //...
);

Coder::insert($data);

更新：为了简化日期，我们可以按照 @Pedro Moreira 的建议使用碳

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'modified_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'modified_at'=> $now
       ),
    //...
);

Coder::insert($data);

更新2：对于 Laravel 5 ，使用 updated_at 代替 modified_at

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'updated_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'updated_at'=> $now
       ),
    //...
);

Coder::insert($data);

Answer 3

读取这一点，查看 createMany()方法。

/**
 * Create a Collection of new instances of the related model.
 *
 * @param  array  $records
 * @return \Illuminate\Database\Eloquent\Collection
 */
public function createMany(array $records)
{
    $instances = $this->related->newCollection();

    foreach ($records as $record) {
        $instances->push($this->create($record));
    }

    return $instances;
}

.

Answer 4

这就是您在更雄辩的方式中进行的方式，

    $allintests = [];
    foreach($intersts as $item){ //$intersts array contains input data
        $intestcat = new User_Category();
        $intestcat->memberid = $item->memberid;
        $intestcat->catid= $item->catid;
        $allintests[] = $intestcat->attributesToArray();
    }
    User_Category::insert($allintests);

.

Answer 5

我很多次搜索它，最后使用了如下所示的自定义生成timestamps：

$now = Carbon::now()->toDateTimeString();
Model::insert([
    ['name'=>'Foo', 'created_at'=>$now, 'updated_at'=>$now],
    ['name'=>'Bar', 'created_at'=>$now, 'updated_at'=>$now],
    ['name'=>'Baz', 'created_at'=>$now, 'updated_at'=>$now],
    ..................................
]);

.

Answer 6

Eloquent::insert是正确的解决方案，但它不会更新时间戳，因此您可以执行以下操作

 $json_array=array_map(function ($a) { 
                        return array_merge($a,['created_at'=> 
                                            Carbon::now(),'updated_at'=> Carbon::now()]
                                           ); 
                                     }, $json_array); 
 Model::insert($json_array);

.

在执行INSERT

之前，该想法是在整个数组上添加Create_AT和Update_At

Answer 7

对于类别关系插入我遇到了同样的问题，除了在我的雄辩模型中，我使用self（）在foreach中拥有同一类的实例来记录多个保存和获取ID。

foreach($arCategories as $v)
{                
    if($v>0){
        $obj = new Self(); // this is to have new instance of own
        $obj->page_id = $page_id;
        $obj->category_id = $v;
        $obj->save();
    }
}

.

没有“$ obj=新self（）”它只节省了单个记录（当$ obj为$以下时）

Answer 8

$start_date = date('Y-m-d h:m:s');        
        $end_date = date('Y-m-d h:m:s', strtotime($start_date . "+".$userSubscription['duration']." months") );
        $user_subscription_array = array(
          array(
            'user_id' => $request->input('user_id'),
            'user_subscription_plan_id' => $request->input('subscription_plan_id'),
            'name' => $userSubscription['name'],
            'description' => $userSubscription['description'],
            'duration' => $userSubscription['duration'],
            'start_datetime' => $start_date,
            'end_datetime' => $end_date,
            'amount' => $userSubscription['amount'],
            'invoice_id' => '',
            'transection_datetime' => '',
            'created_by' => '1',
            'status_id' => '1', ),
array(
            'user_id' => $request->input('user_id'),
            'user_subscription_plan_id' => $request->input('subscription_plan_id'),
            'name' => $userSubscription['name'],
            'description' => $userSubscription['description'],
            'duration' => $userSubscription['duration'],
            'start_datetime' => $start_date,
            'end_datetime' => $end_date,
            'amount' => $userSubscription['amount'],
            'invoice_id' => '',
            'transection_datetime' => '',
            'created_by' => '1',
            'status_id' => '1', )
        );
        dd(UserSubscription::insert($user_subscription_array));

.

UserSubscription是我的型号名称。 如果成功插入“假”，则会返回“真实”。

Answer 9

可以解决这个问题的漫游方式是使用集合和循环它插入模型利用时间戳。

<?php

use App\Continent;
use Illuminate\Database\Seeder;

class InitialSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        collect([
            ['name' => 'América'],
            ['name' => 'África'],
            ['name' => 'Europa'],
            ['name' => 'Asia'],
            ['name' => 'Oceanía'],
        ])->each(function ($item, $key) {
            Continent::forceCreate($item);
        });
    }
}

.

编辑：

抱歉我的误解。为了散装插入这可能会有所帮助，也许可以用这个，你可以制造良好的播种机并优化它们。

<?php

use App\Continent;
use Carbon\Carbon;
use Illuminate\Database\Seeder;

class InitialSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $timestamp = Carbon::now();
        $password = bcrypt('secret');

        $continents = [
            [
                'name' => 'América'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'África'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Europa'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Asia'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Oceanía'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
        ];

        Continent::insert($continents);
    }
}

.

Answer 10

解决问题.............迁移的表格...

$table->timestamp('created_at')->nullable()->useCurrent();

.

易于

Schema::create('spider_news', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('source')->nullable();
            $table->string('title')->nullable();
            $table->string('description')->nullable();
            $table->string('daterss')->nullable();

            $table->timestamp('created_at')->nullable()->useCurrent();
            $table->timestamp('update_at')->nullable()->useCurrent();
        });
