【django】數據庫存儲的方法： 表單.save() 模型.objects.create()

前端傳到後端 view.py中進行數據存儲

數據存儲的方式：

1.表單存儲form.save()

form = Form（request.POST） 

if form.isvalid

        form.save()

 

if request.method == "POST":
    tag_form = ArticleTagForm(data=request.POST)
    if tag_form.is_valid():
        try:
            new_tag = tag_form.save(commit=False)
            new_tag.author = request.user
            new_tag.save()
            return HttpResponse("1")
        except:
            return HttpResponse("數據保存失敗！")
    else:
        return HttpResponse("數據無效！")

 

2. 直接存儲   模型.objects.create()

if request.method == "POST":
    column_name = request.POST['column']
    # 檢查新建的欄目名稱是否存在，如果不存在，允許創建
    columns = ArticleColumn.objects.filter(user_id=request.user.id, column=column_name)
    if columns:
        return HttpResponse("2")  # 2：不允許創建
    else:
        ArticleColumn.objects.create(user=request.user, column=column_name)
        return HttpResponse("1")  # 1：允許創建
