Django的get_absolute_url NoReverseMatch零模式試圖

Question

我一直在努力，現在天使用get_absolute_url，每當我在管理頁面上的視圖中點擊網站上的按鈕，或者點擊提交我的外接窗體頁上，我得到這個錯誤：

NoReverseMatch at /admin/r/14/3/ (or NoReverseMatch at /blogs/add/) 

Reverse for 'blog_detail' with arguments '()' and keyword arguments '{'pk': 3}' not found. 0 pattern(s) tried: [] 

如果我去的mysite /博客/ 3我得到博客的詳細信息頁面就好了，因爲我有它設置。所以我知道該網頁的工作原理，但它似乎沒有試圖找到它，因爲它說零模式嘗試。

文檔我看主要有：（我認爲至少是相關的，如果需要更多的信息讓我知道請）

您需要的命名空間blogs解決網址是這樣的：

return reverse('blogs:blog_detail', kwargs={'pk': self.pk})
