Question

我有一个与用户相距甚远的模式。但是,当我根据这一模式提交表格时,我并没有正确地向用户提供。

class Thing(models.Model):
    """Things."""
    user = models.ForeignKey(User)
    salt = models.IntegerField()
    # [...]

class GenerateThingForm(ModelForm):
    """A form for registering a new Thing."""
    class Meta:
        model = Thing
        fields = (...)    # There are some, but it would distract here

这一观点说:

@login_required()
def register_thing(request):
    """Register Thing."""
    if request.method ==  POST : # If the form has been submitted...
        form = GenerateThingForm(request.POST)
        if form.is_valid():
            form.salt = random.getrandbits(32)
            # Apparently I need to specify form.user.
            # Same result if just request.user
            form.user = User.objects.get(request.user)
            form.save()   # Oh, no!   user_id  is null!

感谢任何倾斜。

如果不将用户或盐类放在形式上,那么它就不知道如何做。将其放在由<代码>格式>生成的一览表上。

thing = form.save(commit=False)
thing.salt = whatever
thing.user = myuser
thing.save()
