django 将模型实例转换为字典

使用Django开发Web应用时，经常需要将模型实例转换为字典的形式，以便于在前端进行展示或者进行其他的数据处理操作。下面将介绍如何在Django中实现这个功能，并提供相应的案例代码。

python
from django.db import models
class Student(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()

python
student = Student.objects.get(id=1)
student_dict = student.__dict__

python
class Class(models.Model):
    name = models.CharField(max_length=100)
class Student(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()
    class = models.ForeignKey(Class, on_delete=models.CASCADE)

python
student_dict['class'] = student.class.name

python
# models.py
from django.db import models
class Student(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()
class Class(models.Model):
    name = models.CharField(max_length=100)
# views.py
from django.shortcuts import render
from .models import Student, Class
def student_detail(request, student_id):
    student = Student.objects.get(id=student_id)
    student_dict = student.__dict__
    # 添加关联字段
    student_dict['class'] = student.class.name
    return render(request, 'student_detail.html', {'student': student_dict})
