将查询集存储在本地存储中

问：

我想存储表单提交的查询集结果，以便在再次访问后恢复其状态。我尝试使用，localStorage，cache，但它们都出现了问题，即 valus 不是将数据保存为查询集，而是存储为字符串。

views.py

def Elective_HD_list(request):
  
    try:
        Elective_list= localStorage.getItem("list_HD")

        form=ElectiveForm_HD()
    except AttributeError:
        Elective_list=[]
        form=ElectiveForm_HD()
    if request.method=="POST":
        form=ElectiveForm_HD(request.POST or None)
        
        if form.is_valid():
               
                Elective_list=form.cleaned_data['Elective_ID']
                request.session['form_data'] = Elective_list
                localStorage.setItem("list_HD",Elective_list) #stored as a string instead of query

               
               
               
    return render(request,"homepage/Elective_HD_list.html",{"form":form,"elective_list":Elective_list})```



Is there a way to store queryset which I can access in further iterations as needed
