Django存储匿名用户数据 [英] Django storing anonymous user data

问题描述

我有一个django模型，从表单输入中存储用户和产品数据：

  def ProductSelection（request，template_name = 'product_selection.html'）：
 ... 
如果user.is_authenticated（）：
 user = request.user 
 else：
＃处理匿名用户信息
 project = Project.objects.create（
 user = user，
 product = form.cleaned_data [product]，
 quantity = form.cleaned_data [product_quantity]， 
）
  

当然这对于经过身份验证的用户来说很好，但我也希望能够存储匿名用户项目，如果可能，最终在用户注册和验证时将它们与用户关联。

我的想法是创建名为= some_variable（timestamp）的匿名用户连接随机哈希？），然后将该用户名保存在会话数据中。如果我确保该会话变量（如果存在）用于记录该用户的所有项目活动，我们应该能够在注册时使用用户的真实凭据更新项目。

$ b $这个过于复杂和脆弱吗？我有风险不必要地节省数千行数据吗？这个常见问题的最佳方法是什么？

对此的任何指导都将不胜感激。

解决方案

可以使用 Django的会话框架来存储匿名用户数据。

然后，您可以向 Project 模型添加一个字段，以保存 session_key $匿名用户的价值

  project = Project.objects.create（
 user = request.user， ＃可以是匿名用户
 session = request.session.session_key，
 product = form.cleaned_data [product]，
 quantity = form.cleaned_data [product_quantity]）
  

或简单地存储项目实例在会话中具有的所有数据

 如果user.is_authenticated（）：
 project = Project.objects.create（
 user = request.user，
 product = form .cleaned_data [product]，
 quan tity = form.cleaned_data [product_quantity]）
 else：
＃处理匿名用户信息
 request.session ['project'] = {
product：form .cleaned_data [product]，
quantity：form.cleaned_Data [product_quantity]} 
  

您可以在创建适当的用户时稍后从会话中检索数据。

I have a django model which stores user and product data from a form input:

def ProductSelection(request, template_name='product_selection.html'):
    ...
    if user.is_authenticated():
        user = request.user
    else:
        # deal with anonymous user info
    project = Project.objects.create(
        user=user,
        product=form.cleaned_data["product"],
        quantity=form.cleaned_data["product_quantity"],
    )

Of course this is fine for authenticated users, but I also want to be able to store anonymous user projects, and if possible, associate them with the user when they eventually register and authenticate.

My idea is to create anonymous user with name = some_variable (timestamp concatenated with a random hash?), then save that username in session data. If I ensure that that session variable, if exists, is used to record all projects activity of that user, I should be able to update the projects with the user's real credentials when they register.

Is this overly complicated and brittle? Do I risk saving thousands of rows of data unnecessarily? What would be the optimal approach for this common issue?

Any guidance on this would be much appreciated.

解决方案

You can use Django's session framework to store anonymous user data.

You can then either add a field to your Project model to hold the session_key value for anonymous users,

project = Project.objects.create(
    user=request.user,  # can be anonymous user
    session=request.session.session_key,
    product=form.cleaned_data["product"],
    quantity=form.cleaned_data["product_quantity"])

or simply store all the data a Project instance would have in the session

if user.is_authenticated():
    project = Project.objects.create(
        user=request.user,
        product=form.cleaned_data["product"],
        quantity=form.cleaned_data["product_quantity"])
else:
    # deal with anonymous user info
    request.session['project'] = {
        "product": form.cleaned_data["product"],
        "quantity": form.cleaned_Data["product_quantity"]}

You can retrieve the data from the session later, when creating a proper user.
