Make column not nullable in a Laravel migration

Question

I\'m writing a migration to make certain columns in a table nullable right now. For the down function, I of course want to make those columns not nullable

Answer 1

You can just declare the column again without ->nullable() and use ->change

public function up()
{
    Schema::table('table_name', function (Blueprint $table) {
        $table->type('column')->change();
    });
}

public function down()
{
    Schema::table('table_name', function ($table) {
        $table->type('column')->nullable()->change();
    });
}
