Question

我需要从代码获取价值并重定向到＆＃39; / value /＆＃39;提交。

现在我得到了：

'ApartmentForm' object has no attribute 'cleaned_data'

我完全错过了一些东西。

forms.py

class ApartmentForm(ModelForm):
    class Meta:
        model = Apartment
        fields = ['title']

views.py

def index(request):
    context = {}
    context['apartments'] = get_list_or_404(Apartment)
    if request.method == 'POST':
        form = ApartmentForm(request.POST or None)
        context = {'form': form,}
        id = form.cleaned_data.get('id', None)
        return redirect(id)
    else:
        context['apartment_form'] = ApartmentForm
        return render(request, 'main/main.html', context)

模板

<form action="/{{ apartment.id }}" method="post">
    {% csrf_token %}
    <p><select size="10">
    <option disabled>Chose apartment</option>
    {% for apartment in apartments %}
        <option value="{{ apartment.id }}">{{ apartment.title }}</option>
    {% endfor %}
    </select></p>
    <input type="submit" value="Chose">
</form>

更新

谢谢丹尼尔！在模板中调用表单是如此的失败。我已修复此问题，但仍将None传递给url（http://127.0.0.1:8000/None）。无法弄清楚原因。

view.py

def index(request):
    context = {}
    context['apartments'] = get_list_or_404(Apartment)
    if request.method == 'POST':
        form = ApartmentForm(request.POST or None)
        if form.is_valid():
            id = form.cleaned_data.get('id', None)
            return redirect(id)
    else:
        context['apartment_form'] = ApartmentForm
        return render(request, 'main/main.html', context)

forms.py

APARTMENTS = ()
for apartment in Apartment.objects.all():
    APARTMENTS += ((apartment.id, apartment.title),)

class ApartmentForm(Form):
    apartment = ChoiceField(label='', widget=Select, choices=APARTMENTS)

模板

<form action="." method="post">
    {% csrf_token %}
    {{ apartment_form }}
<input type="submit" value="Chose">

form.cleaned_data来自form.is_valid()，因此您可以像这样更改views.py：

def index(request):
    [...]
        if request.method == 'POST':
            form = ApartmentForm(request.POST or None)
                if form.is_valid():
                    [...]
                    id = form.cleaned_data.get('id', None)
                    return redirect(id)
