Question

试图循环forms.py内的formset表单，但它仅返回formset的最后一个索引，而不是所有索引。 forms.py：

class MyModelFormSet(BaseModelFormSet):
def clean(self):
    super(MyModelFormSet, self).clean()

    totalforms = self.total_form_count() #to get number of forms in formset

    for form in self.forms:
        for n in range(totalforms):
            d = self[n].cleaned_data['debit'] # if i use  manullay self[0], self[1] it works
        if d == 100:
            raise forms.ValidationError('debit is 100!')
        return d

最终通过NVS评论解决这是更新的代码：首先需要设置一个列表，然后附加到该列表

class MyModelFormSet(BaseModelFormSet):
def clean(self):
    super(MyModelFormSet, self).clean()

    totalforms = self.total_form_count() #to get number of forms in formset
    ds = []
    for form in self.forms:
        for n in range(totalforms):
            d = self[n].cleaned_data['debit']
            ds.append(d)
        if 100 in ds:
            raise forms.ValidationError('debit is 100!')
        return d

Django setset中的帮助循环仅返回form.py中的最后一个索引
