Cannot migrate table using Laravel 4 - laravel

Question

When I try to migrate tables I created I get this error
PHP Fatal error: Class 'Users' not found in /var/www/html/laravel/vendor/laravel/
framework/src/Illuminate/Database/Migrations/Migrator.php on line 301
{"error":{"type":"Symfony\\Component\\Debug\\Exception\\FatalErrorException",
"message":"Class 'Users' not found","file":"\/var\/www\/html\/laravel\/vendor
\/laravel\/framework\/src\/Illuminate\/Database\/Migrations\/Migrator.php",
"line":301}}
Here is my code:
Users table:
<?php
//Users Table
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
class CreateUsersTable extends Migration {
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('users', function(Blueprint $table) {
$table->increments('id');
$table->string('username');
$table->string('email');
$table->string('password');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down(){
}
}
Posts table:
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
class CreatePostsTable extends Migration {
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('posts', function(Blueprint $table) {
$table->increments('id');
$table->string('title');
$table->text('body');
$table->string('m_keyword');
$table->string('m_disc');
$table->string('slug');
$table->integer('user_id');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
}
}

Answer 1

If you get the above error while running a migration, please run the below command
composer dump-autoload

Answer 2

Maybe what has gone wrong is that you did not call
php artisan migrate:rollback
before
php artisan migrate
Try to force delete the tables and try to migrate again.
And another thing. The 'user_id' column in the 'posts' table should be connected to the users table like this:
Schema::table('posts', function(Blueprint $table) {
$table->foreign('user_id')->references('id')->on('users');
});
and I would call the create the table column like this:
$table->unsignedInteger('user_id');
or
$table->integer('user_id')->unsigned();
