使用Django和AJAX表单更新模型值的最简单方法

from django.db import models

class ExampleModel(models.Model):
    value = models.CharField(max_length=100)

from django.shortcuts import get_object_or_404
from django.http import JsonResponse

def update_model_value(request, model_id):
    example_model = get_object_or_404(ExampleModel, id=model_id)
    new_value = request.POST.get('new_value')

    example_model.value = new_value
    example_model.save()

    return JsonResponse({'success': True})

var modelId = 1;  // 模型的ID
var newValue = '新的值';  // 要更新的值

$.ajax({
    url: '/update_model_value/' + modelId + '/',
    type: 'POST',
    data: {
        'new_value': newValue
    },
    success: function(response) {
        if (response.success) {
            console.log('模型值已成功更新！');
        } else {
            console.log('更新模型值失败！');
        }
    }
});
