OctoberCMS -“SQLSTATE [42S22]：未找到列：1054 未知列 'users.application_id'

Question

我收到有关关系的错误消息，但我无法找到我需要做什么来阻止此错误。

我有一个带有控制器和组件的应用程序模型。在后端我可以添加一个新的应用程序记录。但是查看我得到了错误。

  "SQLSTATE[42S22]: Column not found: 1054 Unknown column 'users.application_id' in 'where clause' (SQL: select * from `users` where `users`.`deleted_at` is null and `users`.`application_id` = 1 and `users`.`application_id` is not null limit 1)" on line 662 of /srv/users/sssandwich/apps/website/public/vendor/laravel/framework/src/Illuminate/Database/Connection.php

我隔离了在 fields.yaml 中添加此代码时出现的错误 Acme\Models\Application\fields.yaml.

# ===================================
#  Form Field Definitions
# ===================================

fields:         
    client:
        label: Client
        type: relation
        disabled: true
        select: concat(name, ' ', surname)
        span: left

在

Acme\Models\Application.php

我将关系设置为

/**
     * @var array Relations
     */
    public $hasOne = [
    'client' => ['RainLab\User\Models\User', 'table' => 'users'],
    'cv' => ['Acme\Acme\Models\Cv']
    ];
    public $hasMany = [];
    public $belongsTo = [
    'owner' => ['Backend\Models\User']
    ];

下面是数据库结构...

public function up()
{
    Schema::create('acme_acme_applications', function(Blueprint $table) {
        $table->engine = 'InnoDB';
        $table->increments('id');
        $table->string('jobs_id')->nullable()->index();
        $table->string('application_id')->nullable()->index();
        $table->string('owner_id')->nullable()->index();
        $table->string('user_id')->nullable()->index();
        $table->string('vacancy_id')->nullable()->index();
        $table->string('ref_no', 50)->nullable();
        $table->char('status_update')->nullable();
        $table->timestamps();
    });
}

我已经 grep 了 'application_id'，它只出现在数据库结构中。 users table 是 Rainlab User 插件，但我不确定为什么它试图在 table.

中找到 application_id

 "SQLSTATE[42S22]: Column not found: 1054 Unknown column 'users.application_id'...

我认为这个错误是 self-explanatory 假定应用程序模型具有 application_id 外键，因为您定义了 One-To-One 关系；

如果应用程序 Has-One 用户，则用户的 table 应包含一个 application_id 列：

 public $hasOne = [
    'client' => [
    'RainLab\User\Models\User',
    'table' => 'users',
    'key' => 'application_id', // the foreign key in User's table
    'otherKey' => 'id', // Model record id
        ],
    ];

并且您应该在用户模型中定义反向关系，用户 belongsTo

 public $belongsTo = [
    'application' => [
    'Acme\Models\Application',
    'table' => 'acme_acme_applications',
    'key' => 'application_id',
    'otherKey' => 'id',
        ],
    ];

如果您不想直接编辑 RainLab User 的插件（更改将在更新期间丢失），请查看here它如何扩展插件并向数据库添加多列。
