访问辅助实体的属性

var person = {
  name: "John",
  age: 30
};

console.log(person.name); // 输出 "John"
console.log(person["age"]); // 输出 30

from django.db import models

class Person(models.Model):
    name = models.CharField(max_length=50)
    age = models.IntegerField()

person = Person.objects.get(id=1)
print(person.name)  # 输出 "John"
print(person.age)  # 输出 30

import org.junit.Test;
import static org.junit.Assert.assertEquals;

public class PersonTest {
    @Test
    public void testGetName() {
        Person person = new Person("John", 30);
        assertEquals("John", person.getName());
    }

    @Test
    public void testGetAge() {
        Person person = new Person("John", 30);
        assertEquals(30, person.getAge());
    }
}

SELECT name, age FROM person WHERE id = 1;
