Question

问候Django专家！我在尝试更新django模板中的数据时遇到问题。

我正在尝试在我的django应用程序中实现服务器端分页，为此我使用单个视图联系模型以根据前端返回的值获取数据。

例如：第一次：没有参数从前端发送，因此返回第一页下次：前端发送基于其生成用于渲染的新数据的附加数据

我的问题是新数据（第二次及以后）没有被发送到django模板。它仍然显示相同的旧数据（第一次获取）但是我能够在python控制台上打印new_data，只是在视图返回渲染之前的一步。

我是否缺少任何设置/ Django配置，以便在相同视图的同一模板上呈现新数据。我已经花了足够的时间来解决这个问题，但却未能找到解决方案。

查看对我不起作用的代码段：

def get_category_records(request):

    # Logic which generates data for result variable

    pprint.pprint(result)
    return render(request, 'SampleApp/category_list.html', {'category' : result })

示例模板SampleApp / category_list.html

<!--{% autoescape off %}-->
{{ category }}
<!--{% endautoescape %}-->

我可以看到更新＆＃39;结果＆＃39; django python控制台中的变量值BUt的变化没有反映在django模板中！我的项目的Setting.py
