Formset(表單集)是多個表單的集合。Formset在Web開發中應用很普遍，它可以讓使用者在同一個頁面上提交多張表單，一鍵新增多個數據

class StudentStudyRecordModel(forms.ModelForm):
    class Meta:
        model=StudentStudyRecord
        fields=['score','homework_note']

view檢視

from django.forms.models import modelformset_factory

class Student_study_record(View):
 

def get(self,request):
        model_formset_cls=modelformset_factory(model=StudentStudyRecord,form=StudentStudyRecordModel,extra=0)
        queryset=StudentStudyRecord.objects.filter(classstudyrecord__id=request.GET.get('pk')) #批量操作的queryset
        formset=model_formset_cls(queryset=queryset)
        
 
return render(request, 'students/Student_study_record.html', locals())

    def post(self,request):
        model_formset_cls = modelformset_factory(model=StudentStudyRecord, form=StudentStudyRecordModel, extra=0)
        formset=model_formset_cls(request.POST)　　#與modelform校驗基本一致,就是不用穿instance了
        
 
if formset.is_valid():
            formset.save()
            return redirect('/class_study_record/')
        else:
            print('formset.errors##################',formset.errors)
            return self.get(request)
