        $table->boolean('active')->default(false);
        $table->string('level')->default('user');
        $table->string('first_name');
        $table->string('last_name');
        $table->string('mobile');
        $table->string('birth_date');
        $table->boolean('gender');
        $table->bigInteger('province_id')->unsigned();
        $table->bigInteger('city_id')->unsigned();
        $table->text('address');
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();

        $table->foreign('province_id')->references('id')->on('provinces')->onDelete('cascade');
