Let's say I have a basic model, but I want to add additional fields without deleting the current data. How can I go about doing this? It seems that whenever I update my models, the whole table is being deleted and then re-generated. As a sample, let's say below is by create_tablename.php file:

    class CreateTypesMappingsTable extends Migration
    {

        public function up()
        {
            Schema::create('name_tablename', function($table)
            {
                //Settings
                $table->engine = 'InnoDB';

                //Fields
                $table->increments('id');
                $table->timestamps();
                $table->integer('region_id')->nullable()->default(null);
                $table->integer('country_id')->nullable()->default(null);
                $table->integer('city_id')->nullable()->default(null);
                $table->integer('type_id')->unsigned();

                //Foreign keys
                if(Schema::hasTable('name_tablename2'))$table->foreign('region_id')->references('id')->on('name_tablename2')->onDelete('cascade');
                if(Schema::hasTable('name_tablename3'))$table->foreign('city_id')->references('id')->on('name_tablename3')->onDelete('cascade');
                if(Schema::hasTable('name_tablename4'))$table->foreign('type_id')->references('id')->on('name_tablename4')->onDelete('cascade');

                //Indexes
                $table->index('region_id');
                $table->index('city_id');
                $table->index('type_id');

            });
        }

        public function down()
        {
            Schema::dropIfExists('name_tablename');
        }

    }

you can remove the down method and create the following code (in new file) for example,

<?php namespace Rahman\Galleries\Updates;

use Schema;
use October\Rain\Database\Updates\Migration;

class AddIsPublishedToPetfies extends Migration
{

    public function up()
    {
        if ( ! Schema::hasColumn('rahman_galleries_petfies', 'is_published'))
        {
            Schema::table('rahman_galleries_petfies', function($table)
            {
                $table->boolean('is_published')->after('id')->default(0);
            });
        }
    }

    public function down()
    {
        if (Schema::hasColumn('rahman_galleries_petfies', 'is_published'))
        {
            Schema::table('rahman_galleries_petfies', function($table)
            {
                $table->dropColumn('is_published');
            });
        }
    }

}

update your YAML file and run this code,

php artisan october:up
