Question

我的ModelMultipleChoiceField中的form.py格式如下：

class UserResponseSearchForm(forms.Form):
    def __init__(self, *args, **kwargs):
        qry = kwargs.pop('qry')
        super(UserResponseSearchForm,self).__init__(*args, **kwargs)
        self.fields['gejala_id0'] = forms.ModelMultipleChoiceField(queryset=Gejala.objects.filter(gejala__icontains=qry).values_list('gejala', flat=True).distinct().order_by('gejala'),widget=forms.CheckboxSelectMultiple, required=False)

    gejala_id1 = forms.ModelMultipleChoiceField(queryset=Gejala.objects.all().values_list('gejala', flat=True).distinct().filter(id_organ=1).order_by('gejala'), widget=forms.CheckboxSelectMultiple, required=False)
    gejala_id2 = forms.ModelMultipleChoiceField(queryset=Gejala.objects.all().values_list('gejala', flat=True).distinct().filter(id_organ=2).order_by('gejala'), widget=forms.CheckboxSelectMultiple, required=False)
    gejala_id3 = forms.ModelMultipleChoiceField(queryset=Gejala.objects.all().values_list('gejala', flat=True).distinct().filter(id_organ=3).order_by('gejala'), widget=forms.CheckboxSelectMultiple, required=False)

我的views.py是这样的：

def responsePenyakit(request):
if request.user.is_authenticated:
    if request.method == 'POST':
        form = UserResponseForm(request.POST)
        gejala0 = form["gejala_id0"].data
        gejala1 = form["gejala_id1"].data
        gejala2 = form["gejala_id2"].data
        gejala3 = form["gejala_id3"].data

        if (len(gejala0) > 0):
            for i in range(0, len(gejala0)):
                userAnswer = UserAnswer()
                userAnswer.gejala_answer = gejala1[i]
                userAnswer.user_id = request.user.id
                userAnswer.number_diagnosis = user.number_diagnosis + 1
                userAnswer.save()
                print(gejala0)

        if (len(gejala1) > 0):
            for i in range(0, len(gejala1)):
                userAnswer = UserAnswer()
                userAnswer.gejala_answer = gejala1[i]
                userAnswer.user_id = request.user.id
                userAnswer.number_diagnosis = user.number_diagnosis + 1
                userAnswer.save()

        if (len(gejala2) > 0):
            for i in range(0, len(gejala2)):
                userAnswer = UserAnswer()
                userAnswer.gejala_answer = gejala2[i]
                userAnswer.user_id = request.user.id
                userAnswer.number_diagnosis = user.number_diagnosis + 1
                userAnswer.save()

        if (len(gejala3) > 0):
            for i in range(0, len(gejala3)):
                userAnswer = UserAnswer()
                userAnswer.gejala_answer = gejala3[i]
                userAnswer.user_id = request.user.id
                userAnswer.number_diagnosis = user.number_diagnosis + 1
                userAnswer.save()
    return redirect('diagnosis_penyakit:response_matching')
else:
    raise Http404

我想获取从gejala_id0表格中选择的数据。我尝试像在views.py中那样获取数据。

但是有返回错误Key 'gejala_id0' not found in 'UserResponseForm'.，这是什么问题？我认为我所做的是正确的。 CMIIW

请帮助我。我是django的新人

首先创建字段，然后在__init__中更改查询集。

class UserResponseSearchForm(forms.Form):
    def __init__(self, *args, **kwargs):
        qry = kwargs.pop('qry')
        super(UserResponseSearchForm,self).__init__(*args, **kwargs)
        self.fields['gejala_id0'].queryset = Gejala.objects.filter(gejala__icontains=qry).values_list('gejala', flat=True).distinct().order_by('gejala')

    gejala_id0 = forms.ModelMultipleChoiceField(queryset=Gejala.objects.none(), widget=forms.CheckboxSelectMultiple, required=False)
    gejala_id1 = forms.ModelMultipleChoiceField(queryset=Gejala.objects.all().values_list('gejala', flat=True).distinct().filter(id_organ=1).order_by('gejala'), widget=forms.CheckboxSelectMultiple, required=False)
    gejala_id2 = forms.ModelMultipleChoiceField(queryset=Gejala.objects.all().values_list('gejala', flat=True).distinct().filter(id_organ=2).order_by('gejala'), widget=forms.CheckboxSelectMultiple, required=False)
    gejala_id3 = forms.ModelMultipleChoiceField(queryset=Gejala.objects.all().values_list('gejala', flat=True).distinct().filter(id_organ=3).order_by('gejala'), widget=forms.CheckboxSelectMultiple, required=False)

还将qry发送给表单：

def responsePenyakit(request):
if request.user.is_authenticated:
    if request.method == 'POST':
        form = UserResponseForm(data=request.POST, qry=query)

找不到表格或无法识别表格
