Django外鍵下拉篩選器

Question

我有一個名爲Listing的模型，它基本上是由我的用戶發佈的職位列表。其中一個字段是一個名爲Address的外鍵（因爲用戶可以有多個地址）。這裏是我的models.py：

class JobListing(models.Model): 
    title = models.CharField(max_length=250) 
    description = models.TextField() 
    customer = models.ForeignKey('CustomerAuth.CustomerProfile') 
    address = models.ForeignKey('CustomerAuth.Address') 

這裏是我的forms.py：

class JobListingForm(forms.ModelForm): 
    class Meta: 
     model = JobListing 
     fields = ['title', 'description', 'address', 'customer'] 

最後我views.py的相關部分：

def create_listing(request): 
    form = JobListingForm(request.POST or None) 

    if form.is_valid(): 
     listing = form.save(commit=False) 
     listing.save() 

     current_user = CustomerProfile.objects.get(user=request.user) 
     listing.customer = current_user 
     listing.save() 

     return HttpResponseRedirect('/listings/id/%s' % listing.id) 

    context_dict = {'form': form} 
    return render(request, 'listing/create-listing.html', context_dict) 

因爲它目前爲當用戶從下拉列表中選擇一個地址時，它會顯示每個人的地址。無論如何，我可以過濾它，以便只顯示該用戶輸入的地址。

Answer 1

forms.py

class JobListingForm(forms.ModelForm): 
    class Meta: 
     model = JobListing 
     fields = ['title', 'description', 'address', 'customer'] 

    def __init__(self, user, *args, **kwargs): 
    super(JobListingForm, self).__init__(*args, **kwargs) 
    self.fields['address'].queryset = Address.objects.filter(user=user) 

在您查看文件

def create_listing(request): 
    user = request.user 
    form = JobListingForm(user, request.POST or None) #pass request.user 

Answer 2

嘗試這樣的事情

model1.objects.get(pk=1).model2_set.all()
