Missing required parameters for route in Laravel
提问by steven
in my laravel application whenever i go to this route: /admin or admin/users I get the following error message but the the other routes work like admin/users/create or admin/users/edit:
在我的 Laravel 应用程序中，每当我转到此路由时：/admin 或 admin/users 我收到以下错误消息，但其他路由的工作方式类似于 admin/users/create 或 admin/users/edit：
Missing required parameters for [Route: admin.users.edit] [URI: admin/users/{id}/edit]. (View: C:\xampp\htdocs\CMS\resources\views\admin\index.blade.php)
To note I'm not including all the html code of index.blade.php as it's too long the only blade code is from what i have pasted.
请注意，我没有包含 index.blade.php 的所有 html 代码，因为它太长了，唯一的刀片代码来自我粘贴的内容。
Index.blade view:
Index.blade 视图：
<ul class="nav nav-second-level">
<li>
<a href="{{route('admin.users.edit')}}">All Userss</a>
</li>
<li>
<a href="{{route('admin.users.create')}}">Create User</a>

Here is your error. You missed to pass the variable in route:
这是你的错误。您错过了在路由中传递变量：
<li>
<a href="{{route('admin.users.edit')}}">All Users</a>
</li>
Instead of {{route('admin.users.edit')}}use:
而不是{{route('admin.users.edit')}}使用：
{{route('admin.users.edit', $id)}}
{{route('admin.users.edit', $id)}}
This is actually editing route. If you want to get all users use:
这实际上是编辑路线。如果您想让所有用户使用：
{{route('admin.users.index')}}
{{route('admin.users.index')}}

Change {{route('admin.users.edit')}}to {{route('admin.users.edit', $id)}}and dont forget to change $idto the real id variable :)
更改{{route('admin.users.edit')}}为{{route('admin.users.edit', $id)}}并且不要忘记更改$id为真实的 id 变量:)
And its strange, because you write All usersand giving the edit route :)
这很奇怪，因为您编写All users并提供了编辑路线:)

You are using:
您正在使用：
<a href="{{route('admin.users.edit')}}">All Userss</a>
in your Blade file, but your route is defined like so:
在您的 Blade 文件中，但您的路线是这样定义的：
Route::get('admin/users/{id}/edit', [
'uses' => 'AdminUsersController@edit',
'as' => 'admin.users.edit'
]);
so it's edit action and you need to pas id of user you want to edit for example:
所以它是编辑操作，您需要传递要编辑的用户 ID，例如：
<a href="{{route('admin.users.edit', [auth()->user()->id])}}">All Userss</a>
