WSGIRequest」對象有沒有屬性‘user_slug’，而使用模型從多個應用

Question

在我外鍵的出價「應用程序，我使用‘秩序’爲外鍵從‘訂單’應用作爲

from orders.models import Order 
from sellers.models import SellerCompany 
class Bid(models.Model): 
user = models.ForeignKey(User) 
order = models.ForeignKey(Order) 
company = models.ForeignKey(SellerCompany) 
bid_price = models.DecimalField(max_digits=10, decimal_places=2) 
active = models.BooleanField(default=True) 

在我views.py 的訂單應用程序中，我定義投標視圖

def bid(request, order_slug): 
if UserType.objects.is_seller(request.user): 
    form = BidForm(request.POST or None) 
    if form.is_valid(): 
     new_form = form.save(commit=False) 
     new_form.user = request.user 
     new_form.order.slug = order_slug 
     new_form.company.name = request.company.name 
     new_form.save() 
    return render_to_response('bids/bid.html', locals(), context_instance=RequestContext(request)) 
else: 
    messages.error(request, 'consumer account can not bid') 
    return HttpResponseRedirect('/') 

在我行

new_form.order.slug = request.order_slug 

它顯示了一個錯誤

'WSGIRequest' object has no attribute 'company' 

和其他錯誤是

Bid has no order. 

我forms.py文件投標型號是

from django import forms 
from .models import Bid 
class BidForm(forms.ModelForm): 
class Meta: 
    model = Bid 
    fields = ('bid_price','active') 

通過這個練習中，我試圖order_slug分配到的爲了模型蛞蝓場。和公司以的名稱SellerComapny誰是出價。

您的時間n幫助將不勝感激。

如果您想使用參數「order_slug」，則不必使用請求。你應該使用這個代碼：

new_form.order.slug = order_slug
