Laravel 7 多参数路由错误：Facade\Ignition\Exceptions\ViewException Missing required parameters for Route

Question

My small project was in Laravel 5.8 and i decided to upgrade it to Laravel 7 using copy paste controllers, models, routes &...

Every things is fine but for route has an Associated array, I given this error:

Facade\Ignition\Exceptions\ViewException
Missing required parameters for [Route: admin-user-login] [URI: admin/users/{user}/login]. (View: /home/hamidreza/projects-tmp/laravel7/resources/views/admin/ads-index.blade.php) 

Route:

Route::get('users/{user}/login', 'AdminUserController@login')->name('admin-user-login');

Error section in blade template:

{{ route('admin-user-login', ['user_id' => $ad->user_id]) }}

But it works if i use Indexed array like this:

{{ route('admin-user-login', [$ad->user_id]) }}

Or this one:

{{ route('admin-user-login', $ad->user_id) }}

I need only Associated array, specialy for multi parameter routes.

Your route in web.php wait for paramenter named user , but you put user_id paramenter for it and it throws exeption for you.

In your case in should be something like this:

// config/web.php Route::get('users/{user}/login', 'AdminUserController@login')->name('admin-user-login'); After that, in your controller:

route('admin-user-login', ['user' => $user]);

or:

$user = User::findOrFail($user_id); route('admin-user-login', compact('user'));

or in blade templates: {{ route('admin-user-login', ['user' => $user]) }}
