如何通过一个POST请求从两个不同的模型创建两个对象实例？

# 后端代码示例（使用Python和Django框架）

# models.py
from django.db import models

class ModelA(models.Model):
    field1 = models.CharField(max_length=100)
    # 其他字段...

class ModelB(models.Model):
    field2 = models.CharField(max_length=100)
    # 其他字段...

# views.py
from django.http import JsonResponse
from .models import ModelA, ModelB

def create_objects(request):
    if request.method == 'POST':
        data = request.POST
        field1_data = data.get('field1')
        field2_data = data.get('field2')

        # 创建ModelA对象实例
        model_a = ModelA.objects.create(field1=field1_data)

        # 创建ModelB对象实例
        model_b = ModelB.objects.create(field2=field2_data)

        return JsonResponse({'message': 'Objects created successfully.'})

# 前端代码示例（使用HTML和JavaScript）

<form id="myForm" method="POST" action="/create_objects/">
    <input type="text" name="field1" placeholder="Field 1">
    <input type="text" name="field2" placeholder="Field 2">
    <button type="submit">Submit</button>
</form>

<script>
    document.getElementById('myForm').addEventListener('submit', function(event) {
        event.preventDefault();
        var formData = new FormData(this);

        fetch('/create_objects/', {
            method: 'POST',
            body: formData
        })
        .then(response => response.json())
        .then(data => {
            console.log(data.message);
        })
        .catch(error => {
            console.error('Error:', error);
        });
    });
</script>
