django - 自定义表单中的语法错误

Question

创建自定义表单时，我收到语法错误。错误在最后一行“self.fields ...”中。有谁知道正确的语法？

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

您缺少一个作业标志=：

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

应该：

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