缺少 [Route] 所需的参数

Question

我有这个问题：

Illuminate\\Routing\\Exceptions\\UrlGenerationException 缺少 [Route: admin.percent.edit] [URI: {locale}/admin/percent/edit/{id}] [缺少参数：id] 的必需参数。 （查看：C:\\Users\\kawed\\OneDrive\\Desktop\\flooss\\resources\\views\\admin\\includes\\top.blade.php）

Answer 1

你在 url 中有 2 个参数定义（locale & id）但在你的函数中只有一个 id 所以添加 locale 参数

public function edit(Request $request, $locale, $id) {

或从 url 中删除参数并从请求中使用它
