A noobish question to be sure.

<a href="{% url 'stuff.views.SomeView' %}/somethingnew">
    <button>See something new on this page</button>
</a>

<form action="" method="post">{% csrf_token %}
    <button name="somethingnew" type="submit" value=True>See something new on this page</button>
</form>

With either choice, I update some boolean variable, perform the appropriate calculations, call the page view and render a page with something new on this page. Part of the reason I use either method is to save the state of a collection of boolean variables. What is the best way 1) change a boolean variable 2) save its state 3) perform the necessary updates when the button is clicked and finally 4) render page after the underlying data has been updated?

Right now, I am using forms rather than links so that I don't need to code a url for each boolean variable. Which method is better? Will one method improve the time it takes to reload the page (assuming many boolean variables)?

1) 遵循 REST 思维方式，POST 请求是为了传输用户输入，因为您正在更改数据库对象。

2）如果永远不需要输入（会话持续时间），我会将其保存在 Session 对象中。否则，就像您现在所做的那样在数据库中。

3/4）我会在一个表格中收集所有必要的信息。当用户在 POST 请求中提交表单时，我会计算数据并使用包含计算结果的呈现页面进行响应。如果输入变量是通过间歇性计算逐步收集的，我只需相应地更新输入表单（在组合框中显示不同的选择或类似的东西）。当然，传输也可以通过 AJAXy 方式完成。
