php - 未找到类 'App\Http\Controllers\Search'

Question

我是 Laravel 新手，我们正在尝试将 ( https://github.com/TomLingham/Laravel-Searchy ) 添加到我们的项目 ( https://github.com/wvulibraries/rockefeller-css/tree/trying-searchy ) 以允许搜索表中的多个字段。我可以看到该包作为 tom-lingham 位于供应商文件夹中，由于某种原因我什至无法使用它。我在 DataViewController.php 第 79 行收到 FatalThrowableError:未找到类“App\http\Controllers\Search”。我按照 github 存储库中的说明进行操作。如有任何建议，我们将不胜感激。

public function index(Request $request, $curTable){
// Get the table entry in meta table "tables"
$curTable = Table::find($curTable);
if(!$curTable->hasAccess){
  return redirect()->route('home')->withErrors(['Table is disabled']);
}
// Get and return of table doesn't have any records
$numOfRcrds = DB::table($curTable->tblNme)->count();
// check for the number of records
if ($numOfRcrds == 0){
  return redirect()->route('home')->withErrors(['Table does not have any records.']);

您遇到了命名空间问题。

您的 Controller 位于 App\Http\Controllers 命名空间中，因此默认情况下它会在该命名空间中查找。在 Controller 顶部，在现有的 use 行旁边添加 use Searchy; 行将使其正常工作，或者您可以在前面加上 Searchy 使用 \ 告诉 PHP 从命名空间根开始。

$rcrds = \Searchy::search(...);
