Django: How to set a hidden field on a generic create view?

Question

I'm running Django 1.6.x

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)

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.

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']

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

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

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?

You can do it that way:

• get user from request object.
• overwrite form_valid method on your UserProfileCreateView class,
• attach user to form instance and save it.

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)

This code is for Python 2.7.x
