SQLSTATE [42S22]:找不到列:1054“ where子句”中的未知列“

我不断收到错误

  

“ SQLSTATE [42S22]:找不到列:1054未知列”,其中   条款'“

带有sql输出:

    update `contactables` set `updated_at` = 2019-08-16 20:35:56, `active` = 0 where `` is null and `key_ID` = 235852

我试图在多态模型上使用雄辩的 firstOrNew / firstOrCreate 方法。我已经尝试了各种变体:

  $record1 = Contactable::firstOrNew(
    [
     'contactable_ID' => $location_ID,
     'user_ID' => $user_ID,
     'contactable_type' => Location::class,
    ]);
  $record = Contactable::find($record1->key_ID);
  $record->fill(
    [
     'active' => $active,
    ]);
  $record->save();
    $primaryKey = 'key_ID';
    $guarded = [];
    $fillable = [
        'user_ID',
        'use_loc_contact_info',
        'contactable_ID',
        'contactable_type',
        'active',
        'flag',
        'print_and_save',
        'marketing',
      ];

这似乎仅在尝试更新我实际更改过的记录时发生。创建记录似乎可以正常工作,在我不做任何更改的地方更新似乎可以正常工作。我对下一步的工作一无所知...

我查看了这些(以及十多个与实际无关的其他内容):

我在 Laravel 5.4 中使用了这个修复,与 Kevin Foster 之前的回答非常相似,取自 https://github.com/laravel/framework/issues/5517

在你的 Laravel 模型中插入这个有问题的表 - 插入组合键的列名来代替 column1 和 column2

解决了我的问题 - 感谢之前的贡献者

/**
 * Set the keys for a save update query.
 * This is a fix for tables with composite keys
 * TODO: Investigate this later on
 *
 * @param  \Illuminate\Database\Eloquent\Builder  $query
 * @return \Illuminate\Database\Eloquent\Builder
 */
protected function setKeysForSaveQuery(Builder $query)
{
    $query
        //Put appropriate values for your keys here:
        ->where('column1', '=', $this->column1)
        ->where('column2', '=', $this->column2);

    return $query;
}

您还需要包括:

use \Illuminate\Database\Eloquent\Builder;

经过大量的环顾后,我终于找到了针对此based on this issue I stumbled across的解决方案。我忘记了该表具有复合键,这是此问题的根源。

我将其包含在自定义枢轴模型中,以覆盖“ setKeysForSaveQuery” 的laravel默认值:

class Contactable extends MorphPivot {
    ...
    protected function setKeysForSaveQuery(Builder $query) {
        $query
            //Put appropriate values for keys here:
            ->where('contactable_type', '=', $this->contactable_type)
            ->where('contactable_ID', '=', $this->contactable_ID)
            ->where('user_ID', '=', $this->user_ID);

        return $query;
    }
    ...
}

它像一种魅力一样工作,并解决了导致雄辩地创建...where '' is null and 'key_ID' = 235852查询的问题

我还参考了以下内容,这些内容为我提供了解决方案,但大多数情况下并未解决我过于复杂的自定义复合键多态关系问题。我希望这条路径可以帮助其他人。
