There are two ways to delete associated record or related record. First way is  Suppose we have two models Category and Product. we have association like category has many products. our Category model like this class Category extends Model {     /**      * Get the comments for the blog post.      */     public function products()     {         return $this->hasMany('App\Product', 'category_id');     } } our Product model like this class Product extends Model {     /**      * Get the comments for the blog post.      */     public function category()     {         return $this->belongsTo('App\Category');     } } so write this in your category model. public static function boot() {         parent::boot();         static::deleting(function($category) { // before delete() method call this              $category->products()->delete();              // do the rest of the cleanup.

use Illuminate\Support\Facades\Schema;  public function boot()   {      Schema::defaultStringLength(191);    }

export PATH="$HOME/.composer/vendor/bin:$PATH" source ~/.bash_profile

There are many ways to send data to views from controller i am assuming $data you have to send in view return view('layout',['data' => $data]); return view('layout',compact('data'));  return view('layout')->with(compact('data'));  return view('layout')->withData($data);  return view('layout')->with('data',$data);

make sure you are using create instead of table. use Schema::create to create new. Schema::create('links', function (Blueprint $table) {       $table->increments('id');       $table->timestamps(); }); some this like this

php artisan make:migration create_YOUR_TABLE_NAME_table --create=YOUR_TABLE_NAME For example i am creating links table php artisan make:migration create_links_table --create=links this command will generate migration like this Schema::create('links', function (Blueprint $table) {       $table->increments('id');       $table->timestamps(); });

php artisan key:generate generate key php artisan config:clear clear project cache php artisan config:cache php artisan serve start server again
