Django：如何在通用的创建视图上设置一个隐藏的字段？ [英] Django: How to set a hidden field on a generic create view?

问题描述

我正在运行Django 1.6.x

I'm running Django 1.6.x

为了扩展我的用户，我添加了另一个存储数据的模型：

To extend my user I've added another model storing the data:

class UserProfile (models.Model):
    user = models.ForeignKey(User)`
    height = models.IntegerField(blank=True, null=True)`

现在我想添加一个视图，这是允许用户添加自己的信息在那里开始使用 django.views.generic.edit.CreateView ，但也希望至少提供一个编辑/更新。

Now I wand to add a view, which is allowing the user to add its own infos there. Started with django.views.generic.edit.CreateView, but want also to provide at least the edit/update one to.

所以我添加了导入并创建了一个视图：

So I've added the import and created a view:

from django.views.generic.edit import CreateView, UpdateView
# .... 
class UserProfileCreateView(CreateView):
    model = UserProfile
    fields = ['height']

此外，我还在urls.py中添加了条目：

Also I've added the entry inside urls.py:

    url(r'^userprofile/new/$', login_required(UserProfileCreateView.as_view()), name="add_userprofile")

但是现在我坚持如何以正确的方式分配用户ID。我想让这个字段设置在后台。任何提示？

But now I'm stuck on the point how to assign the user ID in the correct way. I want to have this field set in background. Any hints?

推荐答案

你可以这样做：

• 从请求对象获取用户。


• 覆盖UserProfileCreateView类上的form_valid方法，


• 将用户添加到表单并保存。

class UserProfileCreateView(CreateView):
    model = UserProfile
    fields = ['height']

     def form_valid(self, form):
         user = self.request.user
         form.instance.user = user
         return super(UserProfileCreateView, self).form_valid(form)

此代码适用于Python 2.7.x
