如何从复选框表单Django获取值数组 [英] How to get array of values from checkbox form Django

问题描述

我有这样的HTML表单:

I have HTML form like this:

    <p>Models Sizes IDs:</p>
    <input type="checkbox" name="model_size_ids[]" value="1">XS</input>
    <input type="checkbox" name="model_size_ids[]" value="2">S</input>
    <input type="checkbox" name="model_size_ids[]" value="3">M</input>
    <input type="checkbox" name="model_size_ids[]" value="4">L</input>
    <button>Submit</button>

我正在尝试在我的 View 中接收服务器端的一组检查值:

I'm trying to receive an array of checked values on server side in my View:

size_ids = request.data['model_size_ids[]']

但是，我只能提取一个值和最后一个值.所以如果我检查2-3个值复选框形式，我在视图中仅收到最后一个值.我还尝试命名不带括号的输入字段，结果是相同的.谁能告诉我，我该如何解决?谢谢！

But, I can extract only one and the last value. So if I check 2-3 values in checkbox form, I receive only last value in my view. I also tried to name input field without braсkets and the result was the same. Can anybody tell me, how can I solve that? Thanks!

推荐答案

使用getlist方法获取选定选项的列表

Use the getlist method for geting the list of selected choices

request.POST.getlist('model_size_ids[]')
