Question

控制器：

public function store(CatalogRequest $request, $collectionId)
    {
        $input = $request->all();
        $input['collection_id'] = $collectionId;
        $model = $this->model->create($input);

        return redirect(cms_route('catalog.edit', [$collectionId, $model->id]))
            ->with('alert', fill_data('success', trans('general.created')));
    }

请求：

public function rules()
    {
        $id = $this->route('catalog');
        return [
            'title' => 'required|min:2',
            'slug' => 'required|min:2|unique:catalog,slug,'.$id,
        ];
    }

错误：

array_map(): Argument #2 should be an array

in ValidationRuleParser.php line 89

如果我删除此代码“ unique：catalog，slug'。$ id”，则它正常工作

此行将整个模型绑定到路线：

   SELECT DATE_FORMAT(date, '%m/%d/%Y') AS Dates, count(*) num_entries 
   FROM API_phones 
   WHERE date BETWEEN NOW() - INTERVAL 30 DAY AND NOW() 
   GROUP BY Dates
   ORDER BY Dates ASC

因此，既然有了模型，您就可以从中获取ID：

SELECT DATE_FORMAT(date, '%m/%d/%Y') AS Dates, COUNT(*) AS entry_count
   FROM API_phones 
  WHERE date LIKE '%' AND date BETWEEN NOW() - INTERVAL 30 DAY AND NOW()
  GROUP BY Dates
  ORDER BY Dates ASC

Laravel使用Postgresql错误array_map（）验证唯一性：参数＃2应该是一个数组
