How can I modify a migration in Laravel?

Question

I\'m trying to modify a existing migration. Here is my current migration class:

class CreateLogForUserTable extends Migration
{
    public function up()

You can use the change method, it allows you to modify some existing column types to a new type or modify the column's attributes.

For example modify a column to be nullable:

Schema::table('log_for_user', function ($table) {
    $table->string('error_message')->nullable()->change();
});

But first of all you'll need the doctrine/dbal package

composer require doctrine/dbal
