如何从下拉框中获取值django？ [英] How to get the value from the drop down box django?

问题描述

我应该使用下一个工程吗？

Should I use the next construction?

def PageObjects(request): 
    q = bla_bla_bla(bla_bla) 
    answer = request.POST['value'] 


<form action="PageObjects" method="get">
       <select >
        <option selected="selected" disabled>Objects on page:</option>
        <option value="10">10</option>
        <option value="20">20</option>
        <option value="30">30</option>
        <option value="40">40</option>
        <option value="50">50</option>
       </select>
       <input type="submit" value="Select">
  </form>

我该如何解决这个问题？我需要写什么？

推荐答案

我建议发送您的数据：

<form action="PageObjects" method="post">
  <select >
    <option selected="selected" disabled>Objects on page:</option>
    <option value="10">10</option>
    <option value="20">20</option>
    <option value="30">30</option>
    <option value="40">40</option>
    <option value="50">50</option>
  </select>
  <input type="submit" value="Select">
</form>

您应该通过 clean_data 字典：

def page_objects(request):
  if request.method == 'POST':
    form = YourForm(request.POST)

    if form.is_valid():
      answer = form.cleaned_data['value']

我真的建议您阅读Django文档：

I really recommend that you read the Django docs:

https://docs.djangoproject.com/en/1.4/topics / forms /＃using-a-form-in-a-view
