不基于formset组件的普通写法>>
views：
class RecordScoreView(View): # 录入成绩 def get(self, request,class_study_record_id): class_study_record_obj = ClassStudyRecord.objects.get(pk=class_study_record_id) student_study_record_list = class_study_record_obj.studentstudyrecord_set.all() score_choices = StudentStudyRecord.score_choices return render(request,"study_record/record_score.html",locals()) def post(self, request, class_study_record_id): print(request.POST) data_dict = {} for key, val in request.POST.items(): print(key, val) if key == "csrfmiddlewaretoken": continue # 跳过 field, pk = key.rsplit("_", 1) # 切割 以右为分分一次 if pk not in data_dict: data_dict[pk] = { field: val } else: data_dict[pk][field] = val print(data_dict) for pk, data in data_dict.items(): StudentStudyRecord.objects.filter(pk=pk).update(**data) #StudentStudyRecord.objects.filter(pk=pk).update(**{field:val}) 等同于field = val 打散的格式 return redirect(reverse("class_study_record"))

基于modelformset的写法>>
用modelformset首先得有一个modelform类
class StudentStudyRecordModelForm2(forms.ModelForm): class Meta: model=StudentStudyRecord # 需要编辑校验的字段，不编辑的不协商__all__所有字段 fields=["score","homework_note"]
view:
引入modelformset：
from django.forms.models import modelformset_factory
CBV 视图：
# 基于ModelFormSet 的录入成绩视图| 多个表单 class RecordScoreView2(View): def get(self, request,class_study_record_id): model_formset_cls = modelformset_factory(model=StudentStudyRecord, form=StudentStudyRecordModelForm2, extra=0) #extra=0设置额外增添的编辑表单个数 queryset = StudentStudyRecord.objects.filter(classstudyrecord=class_study_record_id) # 把当前班级对象下面的所有学生学习记录对象传给ModelFormSet # formset每一条学生记录对象做成一个表单对象 formset = model_formset_cls(queryset=queryset) return render(request,"study_record/record_score_formset.html",locals()) def post(self, request,class_study_record_id): model_formset_cls = modelformset_factory(model=StudentStudyRecord, form=StudentStudyRecordModelForm2, extra=0) queryset = StudentStudyRecord.objects.filter(classstudyrecord=class_study_record_id) print("request.POST",request.POST) formset=model_formset_cls(request.POST) if formset.is_valid(): formset.save() print(formset.errors) return redirect(reverse("class_study_record"))
