Currently, Ravel 5.4.23 creates Blade files for common layouts and individual user-only content settings pages for that link.
The following error message occurred while configuring the Blade file link:How can I change the settings without any errors?
Also, if you change the contents of the anchor tag in lines 56-57 of the Blade file for common layout to /channel, etc., there is no specific error.You can also upload the full source, so please let me know.

After creating the database and generating and modifying the migration file, I created the model and controller and performed the migration.
/database/migrations/2014_10_12_000000_create_users_table.php is as follows:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migration;
class CreateUsersTable extensions Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('users', function(Blueprint$table){
$table->increments('id');
$table->string('name');
$table->string('email') ->unique();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('users');
}
}
US>Generated migration file
/database/migrations/2018_04_05_021909_create_channels_table.php has been modified as follows:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;

});
}

In /app/User.php, we added the following:
public function channels(){
return $this->hasMany (Channel::class);
}
Currently, /app/User.phpUser.php is as follows:
<?php
namespace App;
use Illuminate\Notifications\Notify;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extensions Authenticatable
{
use Notify;
/**
* The attributes that are pass assignable.
*
* @var array
*/
protected$fillable=[
'name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
public function channels() {
return $this->hasMany (Channel::class);
}
}
/app/Channel.php has the following conditions:
<?php
namespace App;
use Ravel\Scout\Searchable;
use Illuminate\Database\Eloquent\Model;
class channel extensions Model
{
use Searchable;
protected$fillable=[
'name',
'slug',
'description',
'cover',
'avatar',
];
public function user() {
return$this->belongsTo(User::class);
}
// The getRouteKeyName method is a method for displaying and processing url's permalink in a slug instead of an id.
public function getRouteKeyName(){
return'slug';
}
}
/app/Http/Controllers/ChannelController.php is as follows:
<?php
namespace App\Http\Controllers;
useApp\Jobs\UploadChannelCoverImage;
useApp\Jobs\UploadProfileImage;
use App\Channel;
use Illuminate\Http\Request;
class ChannelController extensions Controller
{
public function show (Channel $channel) {
return view('channel.show',[
'channel' = > $channel
]);
}
public function edit (channel $channel) {
$this->authorize('edit',$channel);
return view('channel.settings',[
'channel' = > $channel
]);
}
public function update (Request $request, Channel $channel) {
$this->authorize('update',$channel);
$this->validate($request,[
'name' = > 'required | max: 255 | unique: channels, name, '.$channel->id,
'slug' = > 'required | max: 255 | alpha_num | unique: channels, slug, '.$channel->id
]);
if($request->file('cover')){
$request->file('cover')->move(storage_path()."/uploads", $fileId=uniqueid(true));
$this->dispatch(new UploadChannelCoverImage($channel,$fileId));
}
if($request->file('avatar')}{
$request ->file('avatar') ->move(storage_path()."/uploads", $fileId=uniqueid(true));
$this->dispatch(new UploadProfileImage($channel,$fileId));
}
$channel->update([
'name' = > $request-> name,
'slug' = > $request->slug,
'description' = > $request->description
]);
return redirect()->to("/channel/{$channel->slug}/settings");
}
}
Routing can be found in /routes/web.php as follows:
<?php
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider with a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', function(){
return view('welcome');
});
Auth::routes();
Route::get('/home', 'HomeController@index') - > name('home');
Route::get('/search','SearchController@index') ->name('search');
Route::group(['middleware'=>['auth']], function(){
Route::get('/account', 'AccountController@show');
Route::post('/account', 'AccountController@update');
Route::get('/channel/{channel}/settings', 'ChannelController@edit');
Route::post('/channel/{channel}/settings', 'ChannelController@update');
});
Auth::user()->channels() is probably null.
Check to see if the current user has a channel record.
