Question

对不起，我是初学者。如何将变量/值x =“ ABCDE”传递给表单？

#views.py
     ...
     x = "ABCDE"
     form1 = KSS_Form1(initial={'x':x})
     context = {'form':form1, **context}
     return render(request, 'af/size/01_kss_size2.html', context)

#forms.py
class KSS_Form1(forms.Form):
    mat_geh_innen = forms.ChoiceField(choices=[], widget=forms.Select())
    def __init__(self, *args, **kwargs):
         super(KSS_Form1, self).__init__(*args, **kwargs)
         self.initial['mat_geh_innen'] = x
         self.fields['mat_geh_innen'].choices = \
            [(i.id, "Housing: " + i.mat_housing.descr) \
            for i in afc_select_housing_innenteile.objects.filter(Q(series__valuefg__exact=x) & Q(anw_01=True))]

目前，我收到一条错误消息 Exception Value: name 'x' is not defined

如果表单中有许多不同的ChoiceField，如何传递2、3或更多的值？

谢谢

您可以从self.initial字典中获得此信息：

＃forms.py

class KSS_Form1(forms.Form):
    mat_geh_innen = forms.ChoiceField(choices=[], widget=forms.Select())
    
    def __init__(self, *args, **kwargs):
         super().__init__(*args, **kwargs)
         self.fields['mat_geh_innen'].initial = self.initial['x']
         self.fields['mat_geh_innen'].choices = [
             (i.id, 'Housing: ' + i.mat_housing.descr)
             for i in 
             afc_select_housing_innenteile.objects.filter(series__valuefg=x, anw_01=True)
         ]

但是，您可能希望使用ModelChoiceField [Django-doc]，以便更轻松地选择模型对象。
