[英]Django Attribute Error: 'function' object has no attribute 'is_usable'
[英]Django attribute error: 'module' object has no attribute 'is_usable'
在Django中調用url時出現以下錯誤。 它之前正在工作,我想這與我所做的一些偶然變化有關,但我不知道它們是什么。
羅伯特,謝謝你的幫助

看起來Django正在尋找一個可用的模板加載器,但是在settings.TEMPLATE_LOADERS
中發現了一些不符合模板加載器功能協議的東西( 這里簡要描述)。
您最近的更改之一是settings.TEMPLATE_LOADERS
還是自定義模板加載器? 如果是后者,您的模板函數需要一個is_usable
屬性,大概設置為True
。
