次のように、特定のオブジェクトを作成しているユーザーをデータベースに保存する必要があります。
(models.py)
class Address(models.Model):
createdBy = models.ForeignKey(User)
address1 = models.CharField("Address Line 1", max_length=40)
address2 = models.CharField("Address Line 2", max_length=40, blank=True)
city = models.CharField(max_length=20)
state = models.CharField(max_length=3)
zipCode = models.CharField("Postal Code", max_length=10)
フォームを処理するための私のビューはここにあります(views.py):
def handlePopAdd(request, addForm, field):
if request.method == "POST":
form = addForm(request.POST)
if form.is_valid():
try:
newObject = form.save(request)
except forms.ValidationError, error:
newObject = None
if newObject:
return HttpResponse('<script type="text/javascript">opener.dismissAddAnotherPopup(window, "%s", "%s");</script>'% (escape(newObject._get_pk_val()), escape(newObject)))
else:
form = addForm()
pageContext = {'form': form, 'field': field}
return render_to_response("address_popup.html", pageContext, context_instance=RequestContext(request))
そして最後に、これが私のフォームコードです: (forms.py)
class AddressForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
self.request = kwargs.pop('request', None)
return super(AddressForm, self).__init__(*args, **kwargs)
def save(self, *args, **kwargs):
obj = super(AddressForm, self).save(commit=False)
if self.request:
obj.createdBy = self.request.user
obj.save()
class Meta:
model = Address
exclude = ('createdBy',)
私はこの質問で提案されたトップの回答を使用していますが、数時間この穴を見つめた後、壁にぶつかりました。
これが私のトレースバックです。エラーは/app/address/add/ の IntegrityError です (1048、「Column 'createdBy_id' cannot be null」)
