从django

Question

在我的视图中。 我正在尝试发送表单类中不存在的附加变量，因为我在HTML文件中定义了它。 答案不是在表单类中定义它。 例如，我还有其他不会将其播放到Django表单定义的HTML小部件。

def AnalyseDoc(request):
    doctype=""
    if request.method == "POST":
        form = AnalyseForm(request.POST, request.FILES)
        if form.is_valid():
            filecontent = request.FILES['filename']
            doctype=form.cleaned_data['doctype']
            # dummydata=form.cleaned_data['dummydata']
            print(dummydata)
            analyse = analyseStuff(file=filecontent,doctype=doctype, dummydata=dummydata)
    else:
        form = AnalyseForm()

    return render(
                    request, 
                    "summary.html", 
                    {
                        "dummydata": "x",
                        "form": form,
                        'filecontent': filecontent,
                        "doctype": doctype,
                    },
                )

这有点难

    <h1>What file would you like to Analyse?</h1>
    <form action = "" method = "post" enctype="multipart/form-data">
        <div class="form-check form-switch">
            <label class="form-check-label" for="dummydata">Use Dummy Data</label>                    
            <input class="form-check-input" type="checkbox" role="switch" id="dummydata" checked>
        </div>
            {% csrf_token %}
        {{form | crispy}}
        <button id="submit" type="submit" class="btn btn-primary">Analyse<button>
    </form>  

如何在这种情况下访问“ dummydata”的值

显然，我无法从Cleaned_Data获取内容。这不是正式的形式领域。 我看不到使用

request.POST.get('dummydata')

关于我如何在视图功能中访问dummydata的任何想法？

在您的情况下，您需要做的所有事情都指定了复选框的

名属性。这也是一个可能有帮助的link

。这样的东西：

<form action = "" method = "post" enctype="multipart/form-data">
  <div class="form-check form-switch">
    <label class="form-check-label" for="dummydata">Use Dummy Data</label>
    <input class="form-check-input" type="checkbox" role="switch" id="dummydata" checked name="dummy">
  </div>
    {% csrf_token %}
  {{form | crispy}}
  <button id="submit" type="submit" class="btn btn-primary">Analyse</button>
</form>

然后

request.POST
