Question

こんにちは私はプロファイリングシステムを実装しようとしています。ユーザーがログインするとすぐに、学生は識別され、学生モデルから情報を引き出して、システム内のページ。また、うまくいけば

私はこのエラーを取得します.... URLの最後に学生のユーザー名を追加します：

profile() missing 1 required positional argument: 'username'

Answer 1

def profile(request, username):  

views.profileは、あなたが経過していない要求とともに追加の引数を取ります。

url(r'^$', views.profile, name='profile') 

Answer 2

あなたprofileビューがusername引数が必要ですが、あなたのURLの構造は、それを定義していません。

url(r'^profile/(?P<username>[\w\d]+)/$', views.profile, name='profile')) 

のようなものを先頭にprofile一部をライン

url(r'^$', views.profile, name='profile')) 

を変更することは、あなたのindex URLからそれを区別するために追加されます。
