自定義表單中的語法錯誤

Question

創建自定義表單時，我在語法中收到錯誤。錯誤發生在最後一行「self.fields ...」中。有誰知道正確的語法？

class UpdateStateWithOptionsForm(forms.ModelForm): 
    class Meta: 
     model = State 


    def __init__(self, *args, **kwargs): 
     super(UpdateStateWithOptionsForm, self).__init__(*args, **kwargs) 
     self.fields['relevantoption']forms.ModelMultipleChoiceField(queryset=Option.objects.all(),required=True, widget=forms.CheckboxSelectMultiple) 

Answer 1

你缺少一個分配標誌=：

self.fields['relevantoption']forms.ModelMultipleChoiceField(queryset=Option.objects.all(),required=True, widget=forms.CheckboxSelectMultiple) 

應該是：

self.fields['relevantoption'] = forms.ModelMultipleChoiceField(queryset=Option.objects.all(),required=True, widget=forms.CheckboxSelectMultiple)
