遷移Django的1.1.1 - > 1.2.1：{％URL％}

Question

我移植一個Django項目從1.1.1到1.2.1

現在既不是{% url %}標籤不起作用的作品，也不是@models.permalink -decorated get_absulute_url工作

即我得到

TemplateSyntaxError at/
Caught TypeError while rendering: __init__() got an unexpected keyword argument 'error_message' 

爲

<li><a href="{% url archive_talks %}">talks</a></li> 

而URL模式是這樣的：

url(r'^archive/talks/$', 'talkapp.views.archive_talks', name="archive_talks"), 

有沒有人遇到同樣的問題？有解決方案嗎？

Answer 1

這個問題無關與實際{% url %}標籤。您在該標籤上觸及它的原因是URL反轉過程實際上會導入您所有的Django視圖，並且在完全不同的位置出現錯誤：BlogForm類。

沒有這種形式的代碼，很難確切地說出那裏有什麼問題，儘管它似乎通過了error_message參數，而不是error_messages（帶有s）。
