Django下拉列表过滤器与ajax?

当用户选择下拉列表的值时,我需要更新模板。有可能通过ajax调用或类似方法执行此操作吗?完美的是,如果用户选择下拉列表的值,则该值将被发送到我的视图,并且页面中的内容将更新而无需刷新页面。

我尝试了不同的方法,但是没有任何效果。欢迎任何建议。

这是我的简化代码:

models.py

class Author(models.Model):
      id = models.IntegerField(primary_key=True)
      author = models.CharField(max_length=50)
      status = models.CharField(max_length=50)          

      [...]

views.py

def authors(request):
     authors = Author.objects.all()
     if request.method="GET":
         authors = Author.objects.filter(status = filter)

模板

<div class="dropdown">
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    Choose status
  </button>
  <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
    <a class="dropdown-item" href="#">Staff</a>
    <a class="dropdown-item" href="#">Admin</a>
          [...]
  </div>
</div>

{% for author in authors %}
{{author.author}}
{% endfor %}
