Django格式。如何从表单初始化模型字段？

在models.py中：

class Client(AbstractBaseUser):

    username = models.CharField(max_length=32, unique=True)
    email = models.EmailField('email address', unique=True, db_index=True)
    avatar = models.ImageField('avatar', upload_to='avatars')
    id = id(object)

class Order(models.Model):
    class Meta():
        db_table = 'order'

    short_desc = models.CharField(max_length=30)
    subject = models.ForeignKey(Subject, blank=True)
    user_id = models.ForeignKey('Client', to_field='id', related_name='client_id', default='0', blank=True)
    performer_id = models.ForeignKey('Client', to_field='id', related_name='performer_id', default='0', blank=True)
    worktype = models.ForeignKey(Type, blank=True)
    level = models.IntegerField(default=0, blank=True)
    readiness = models.BooleanField(default=False, blank=True)
    description = models.TextField(max_length=2000, blank=True)
    file = models.FileField(upload_to='orderfiles', blank=True)
    #maxdate = models.DateField(blank=True)
    addate = models.DateField(auto_now=True, blank=True)
    price = models.IntegerField(max_length=10, blank=True)
    responses = models.IntegerField(blank=True)

在forms.py中：

class AddOrderForm(forms.ModelForm):

    short_desc       = forms.CharField(widget=forms.TextInput,label="Краткое описание(послужит именем)")
    subject          = forms.ModelChoiceField(queryset=Subject.objects.all(), label="Предмет")
    worktype         = forms.ModelChoiceField(queryset=Type.objects.all(), label="Тип")
    level            = forms.IntegerField(widget=forms.TextInput,label="Уровень сложности (от 1 до 5)")
    description      = forms.CharField(widget=forms.TextInput,label="Полное описание")
    #maxdate          = forms.DateField(widget=forms.TextInput,label="maxdate")
    price            = forms.IntegerField(widget=forms.TextInput,label="Ваша цена")
    responses        = forms.IntegerField(widget=forms.TextInput,label="Кол-во ответов на заказ")

    class Meta:
        model = Order
        fields = ['short_desc',  'level', 'description', 'price', 'responses', 'subject', 'worktype']

在views.py中：

def addorder(request, user_id):
    """
    Adding Order view
    """
    if request.POST:
        form = AddOrderForm(request.POST)

        if form.is_valid():

            form.save()

            return redirect('/')


    else:
        return redirect('/')
    auth1 = auth.get_user(request).username
    return render_to_response('customer.html', { 'form': form,'username' : auth1}, context_instance=RequestContext(request))

我需要在

添加
ing
Order（）
之后立即初始化
class Order
中的
user\u id
字段。我应该在哪里做，用哪种方式？我需要这样的逻辑：
Client
通过
AddOrderForm
添加一个
Order
，然后刚刚添加的
class Order
对象的
user\u id
字段必须用
class Client
对象初始化，该对象的id等于
addorder（）参数中的
user\u id
函数。
您可以在保存表单时使用
commit=False
执行此操作。这是使用字段较少的模型表单保存对象的典型方式

def addorder(request, user_id):
    """
    Adding Order view
    """
    if request.POST:
        form = AddOrderForm(request.POST)

        if form.is_valid():

            order = form.save(commit=false)
            order.client_id = Client.objects.get(id=user_id)
            order.save()

            return redirect('/')


    else:
        return redirect('/')
    auth1 = auth.get_user(request).username
    return render_to_response('customer.html', 
             { 'form': form,'username' : auth1}, 
             context_instance=RequestContext(request))

免责声明：处理错误，例如
Client.objects.get（）
可能会失败。使用适当的字段进行搜索。
您使用integerField的textInput小部件有什么正当理由吗？您可以使用详细名称，而不是重新定义表单中的所有字段。
