Question

我无法从以下POST表单中获取正确的数据：

view.py

queryset=ExampleT.objects.filter(id=var_id).order_by('value1')
form = HiddenForm(initial={'ids': [o.id for o in queryset]})
return render(request, 'test.html', {'form': form})

form.py

class HiddenForm(forms.Form):
ids = forms.MultipleChoiceField(widget=forms.MultipleHiddenInput())

输出：

<input id="id_ids_0" name="ids" type="hidden" value="10" />
<input id="id_ids_1" name="ids" type="hidden" value="1" />
<input id="id_ids_2" name="ids" type="hidden" value="2" />

这是request.POST：

的值

<QueryDict: {u'csrfmiddlewaretoken': [u'g2ktgFpDA5aa3BK2Baaes2nAexxKKh4Y'], u'ids': [u'1', u'2', u'10']}>

如何在数组中获得3个值，可能是[10,1,2]的顺序？

我尝试过这段代码，但只返回一个值：

var_for=request.POST.get('ids')
    for tmp_var in range(len(var_for)):
        print var_for[tmp_var]

Answer 1

试试这个 form = HiddenForm（request.POST）如果form.is_valid（）： var_for = form.cleaned_data [＆＃39; ids＆＃39;]

Answer 2

始终使用form.cleaned_data并检查form.is_valid()

def myview(request):

    if request.method == 'POST': # If the form has been submitted...
        form = HiddenForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass
            # Process the data in form.cleaned_data
            # ...
            ids = form.cleaned_data['ids']
            # ... return some sort of http response
    else:
        queryset=ExampleT.objects.filter(id=var_id).order_by('value1')
        form = HiddenForm(initial={'ids': [o.id for o in queryset]})

    return render(request, 'test.html', {'form': form})
