'Undefined index: Driver' 使用 neo4j 作为 laravel 表单的数据库时出错

Question

我的场景：我使用 laravel php 框架编写了一个表单。我希望将该表单数据保存到图形数据库（Neo4j DB）中。这是我的 app/config/database.php。

<?php

return array(

    /*
    |--------------------------------------------------------------------------
    | PDO Fetch Style
    |--------------------------------------------------------------------------
    |
    | By default, database results will be returned as instances of the PHP
    | stdClass object; however, you may desire to retrieve records in an
    | array format for simplicity. Here you can tweak the fetch style.
    |
    */

    'fetch' => PDO::FETCH_CLASS,

    /*
    |--------------------------------------------------------------------------
    | Default Database Connection Name
    |--------------------------------------------------------------------------
    |
    | Here you may specify which of the database connections below you wish
    | to use as your default connection for all database work. Of course
    | you may use many connections at once using the Database library.
    |
    */

    'default' => 'neo4j',

    /*
    |--------------------------------------------------------------------------
    | Database Connections
    |--------------------------------------------------------------------------
    |
    | Here are each of the database connections setup for your application.
    | Of course, examples of configuring each database platform that is
    | supported by Laravel is shown below to make development simple.
    |
    |
    | All database work in Laravel is done through the PHP PDO facilities
    | so make sure you have the driver for your particular database of
    | choice installed on your machine before you begin development.
    |
    */

    'connections' => array(

        'sqlite' => array(
            'driver'   => 'sqlite',
            'database' => __DIR__.'/../database/production.sqlite',
            'prefix'   => '',
        ),

        'mysql' => array(
            'driver'    => 'mysql',
            'host'      => 'localhost',
            'database'  => 'appdb',
            'username'  => 'root',
            'password'  => 'password',
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
        ),

        'pgsql' => array(
            'driver'   => 'pgsql',
            'host'     => 'localhost',
            'database' => 'forge',
            'username' => 'forge',
            'password' => '',
            'charset'  => 'utf8',
            'prefix'   => '',
            'schema'   => 'public',
        ),

        'sqlsrv' => array(
            'driver'   => 'sqlsrv',
            'host'     => 'localhost',
            'database' => 'database',
            'username' => 'root',
            'password' => '',
            'prefix'   => '',
        ),
        'neo4j' => array(
            'host'     => 'localhost',
            'port'     => 7474,
            'username' => null,
            'password' => null,
        ),

    ),

    /*

    |
    */

    'migrations' => 'migrations',

    /*

    | such as APC or Memcached. Laravel makes it easy to dig right in.
    |
    */

    'redis' => array(

        'cluster' => false,

        'default' => array(
            'host'     => '127.0.0.1',
            'port'     => 6379,
            'database' => 0,
        ),

    ),
);

面临的问题：当我填写该表格并按下提交按钮时，数据不会被推送到 neo4j DB。它显示错误：错误异常 (E_UNKNOWN) 未定义索引：驱动程序

预期结果：单击提交按钮时，需要将表单数据保存在 neo4j DB 中。

Answer 1

我设法修复了它：我决定使用 Vinelabs\NeoEloquent 包。 Link 是 here。
我将 neoeloquent 包要求添加到 compser.json 文件，运行 composer update 命令。然后我将该包添加到 app/config/app.php 中的 providers 数组，然后我像这样替换 app\config\database.php 中的连接数组：

'connections' => [
            'neo4j' => [
                    'driver' => 'neo4j',
                    'host'   => 'localhost',
                    'port'   => '7474',
                    'username' => null,
                    'password' => null
            ]
    ],

然后我编写了自己的模型文件来将表单数据推送到 neo4j 数据库中。它奏效了。
