问题描述
如何使django formset中的所有表单都需要？我试图验证在 clean_data 中覆盖formset的clean（）方法的所有字段的存在，但它只是默认地失败，没有显示任何错误。
How to make all forms in django formset required? I tried to validate presence of all fields in cleaned_data overriding formset's clean() method but it just fails silently without any error displayed.
谢谢！
源代码：
class BaseScheduleForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(BaseScheduleForm, self).__init__(*args, **kwargs)
self.fields['day'].widget = forms.HiddenInput()
self.fields['user'].widget = forms.HiddenInput()
class Meta:
model = Schedule
def clean_end_time(self):
start_time = self.cleaned_data.get('start_time')
end_time = self.cleaned_data['end_time']
if start_time and end_time:
if end_time <= start_time:
raise forms.ValidationError("End time must be later that start time.")
return end_time
class BaseScheduleFormset(forms.models.BaseModelFormSet):
def __init__(self, *args, **kwargs):
super(BaseScheduleFormset, self).__init__(*args, **kwargs)
for number, weekday in enumerate(WEEKDAYS):
self.forms[number].day_name = weekday[1]
def clean(self):
raise forms.ValidationError('You must specify schedule for the whole week')
ScheduleFormset = forms.models.modelformset_factory(Schedule, extra=7, max_num=7,
form=BaseScheduleForm, formset=BaseScheduleFormset)
有一天有7个表单，所有这些表单必须填写才能有效。在上面的例子中，我刚刚尝试在clean中引发错误。 is_valid（）变为False，但没有显示错误。
There are 7 forms each for one day and all of them must be filled to be valid. In example above I just tried to raise error in clean. is_valid() became False, but no errors were displayed.
推荐答案
这很难理解哪里错误没有显示。
It's a bit hard to understand where the errors are not being displayed.
如果is_valid是False，那么很好，自己的验证正在工作。接下来的地方就是模板层。你怎么检查错误？ {{form.errors}}或{{somefield.errors}}。
If is_valid is False, then good, the validation it self is working. Then the next place to look is for the templating layer. How are you checking for errors? {{form.errors}} or {{somefield.errors}}.
清洁方法在这里设置的方式，他们的错误不会与任何字段相关联，但应该在全部错误插槽中。
The way the clean methods are setup here, their errors will not be associated with any fields, but should go in the all erros slot.
