Now. let’s go we will solve the above error. first, open the AppServiceProvider.php file from the app/Providers/ directory. after then we will load the schema “use IlluminateSupportFacadesSchema;” on the top header and set the “Schema::defaultStringLength(191);” into boot method.
You can see the below code, therefore, then you can better understand.
<?php
namespace AppProviders;
use IlluminateSupportServiceProvider;
use IlluminateSupportFacadesSchema;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
//
Schema::defaultStringLength(191);
}
}
?>
After the above changes, you can again migrate the table and then it will be successfully migrated.Read AlsoLaravel 6 Image Upload Tutorial ExampleLaravel 6 Ajax Image Upload Example TutorialLaravel 6 Multiple Image Upload Example Tutorial
