#引用modelformset from django.forms.models import modelformset_factory #必須繼承forms.ModelForm！ class StudentStudyRecordModelForm(forms.ModelForm): class Meta: #需要建立關聯的表StudentStudyRecord model = StudentStudyRecord #score", "homework_note 顯示的欄位 fields = ["score", "homework_note"]

class RecordScoreView(View): def get(self, request, class_study_record_id): # modelformset_factory固定的寫法 ，model=StudentStudyRecord這是需要關聯的表名，form後邊是我們上邊的新建類名 ， extra=0 不加它預設資料多一行 model_formset_cls = modelformset_factory(model=StudentStudyRecord, form=StudentStudyRecordModelForm, extra=0) queryset= StudentStudyRecord.objects.filter(classstudyrecord=class_study_record_id) print(class_study_record_id) #2 第2天的課程 print("queryset",queryset) #查詢第2天課程的學生記錄 formset = model_formset_cls(queryset=queryset) return render(request, "record_score.html", locals()) defpost(self, request, class_study_record_id): model_formset_cls = modelformset_factory(model=StudentStudyRecord, form=StudentStudyRecordModelForm, extra=0) queryset = StudentStudyRecord.objects.filter(classstudyrecord=class_study_record_id) # print("request.POST", request.POST) formset = model_formset_cls(request.POST) #??????????????????????????????// print("formset",formset) print(123456789) #判斷是否通過校驗 if formset.is_valid(): formset.save() # print(formset.errors) return redirect(request.path)
