Answer 1

端折った解答をしますと、 views.py の以下行だけでは、データが何も入っていないのではないかと思いました。

question_D = question.objects.filter(Profile_A.user=request.user)

ですので、試しに動かす文には、 question_D に以下のような具合でデータを入れてはいかがでしょう。（「インスタンスを作る」工程が抜けているとも言えます）

question_D = question(title="テストです", pageurl="http://example.com", urltype=urltype_choice.nanika,text="ローレンイプサム", user=jonhdoe)
question_D = question.objects.filter(Profile_A.user=request.user)

ちなみに、私はDjango詳しくないので、参考程度にとどめていただければと思います。
