Question

我想从Django模板的python代码中接收变量值。我有两个按钮Yes和No。当我单击按钮之一时，我的python代码必须接收此django变量并检查True或False。但是我找不到有关如何使用这些变量的信息。这是我的html代码：

{% with word=words|random %}
<h1>{{ word }}</h1>
<h1>{{ word.word_ru }}</h1>
<form method="POST">
    {% csrf_token %}
<input type="submit" value="no" name="Answer" >
<input type="submit" value="yes" name="Answer" >
{% endwith %}

这是我的python代码：

def index(request):
    if request.method == "POST" and request.POST.get("Answer") == 'no':
        return render(request, "training/training.html", {})
    else:
        return render(request, "training/training.html", {})

Answer 1

您可以这样重写代码：

# template file

{% with word=words|random %}
<h1>{{ word }}</h1>
<h1>{{ word.word_ru }}</h1>
<form method="POST">
    {% csrf_token %}
        <input type="submit" value="no" name="answer_yes" >
        <input type="submit" value="yes" name="answer_no" >
{% endwith %}

然后是views.py文件：

# views file

def index(request):
    if 'answer_yes' in request.POST:
        my_answer = request.POST.get('answer_yes')
        return render(request, "training/training.html", {'Answer': my_answer})
    elif 'answer_no' in request.POST:
        my_answer = request.POST.get('answer_no')
        return render(request, "training/training.html", {'Answer': my_answer})

应该可以，但是我没有测试。

编辑：

您可以这样隐藏变量：

<input type="hidden" value={{ word }} name="word" >

然后，从此命令获取变量值：

if request.POST:
    my_answer = request.POST.get('word')

Answer 2

如下

def test_view(request):
    answer = True if request.POST.get("Answer") == "yes" else False

Answer 3

通过隐藏的输入类型发送单词变量，或者通过ajax发送。如果我理解正确，您想发送可变单词到您的视图吗？按钮值工作正常吗？

<form method="POST">
{% csrf_token %}
<input type="submit" value="no" name="Answer" >
<input type="submit" value="yes" name="Answer" >
<input type="hidden" value={{word}} name="word" >
</form>
