django modelformse批量编辑 查询学生班级成绩

复杂版

将字段设置联合唯一

class Meta:    unique_together=["student","classstudyrecord"]

 1 class ClassStudyRecordView(View):
 2     def get(self,request):
 3         ClassStudyRecordlist=ClassStudyRecord.objects.all()
 4         return render(request,"ClassStudyRecord.html",{"ClassStudyRecordlist":ClassStudyRecordlist})
 5

 8     def post(self, request):
 9         print(request.POST)
10         func_st = request.POST.get("action")
11         num = request.POST.getlist("selected_pk_list")
12
13         print("num", num)
14         if not hasattr(self, func_st):
15             return HttpResponse("非法输入")
16         else:
17             func = getattr(self, func_st)
18             queryset = ClassStudyRecord.objects.filter(pk__in=num)
19
20             print("queryset", queryset)
21             ret = func(request, queryset)
22             if ret:
23                 return ret
24             return redirect(request.path)
25         #批量删除
26     def patch_delete(self, request, queryset):
27         queryset.delete()
28         #批量查询,利用跨表查询查询创建字段,为了避免添加重复使用联合唯一
29     def patch_choice(self,request,queryset):
30         try:
31             for i in queryset:
32                 for item in i.class_obj.student_set.all():
33                     StudentStudyRecord.objects.create(student=item,classstudyrecord=i)
34         except Exception as e:
35             pass

views.py

跳转页面进行编辑,通过获取form的值构成列表循环录入成绩

 1 def buhui(request,id):
 2
 3     if request.method=="GET":
 4         ret=StudentStudyRecord.objects.filter(classstudyrecord_id=id)
 5         return  render(request,"student_std.html",locals())
 6     else:
 7
 8         user = request.POST.getlist("user")
 9         homework = request.POST.getlist("homework")
10         for a,item in enumerate(ClassStudyRecord.objects.filter(pk=id).first().class_obj.student_set.all()):
11             print(a,item)
12             StudentStudyRecord.objects.filter(student=item).update(score=user[a],homework_note=homework[a])
13         return redirect(request.path)

views.py录入成绩

modelformset 简单版

1.首先引入模块

from django.forms.models import modelformset_factory

2.

后端

 1 from django.forms.models import modelformset_factory
 2
 3 class StudentStudyRecordModelForm(forms.ModelForm):
 4     class Meta:
 5         model=StudentStudyRecord
 6         fields=["score","homework_note"]
 7
 8 class RecordScoreView(View):
 9
10     def get(self, request,class_study_record_id):
11 #modelformset_factory()里面需要2个变量,model和modelform,extra默认为1,显示添加
12         model_formset_cls=modelformset_factory(model=StudentStudyRecord,form=StudentStudyRecordModelForm,extra=0)
13         queryset = StudentStudyRecord.objects.filter(classstudyrecord=class_study_record_id)
14         formset = model_formset_cls(queryset=queryset)
15         return render(request,"student/record_score.html",locals())
16
17     def post(self, request,class_study_record_id):
18         model_formset_cls = modelformset_factory(model=StudentStudyRecord, form=StudentStudyRecordModelForm, extra=0)
19         queryset = StudentStudyRecord.objects.filter(classstudyrecord=class_study_record_id)
20         print("request.POST",request.POST)
21         formset=model_formset_cls(request.POST)
22         if formset.is_valid():
23             formset.save()
24
25         print(formset.errors)
26
27         return redirect(request.path)
