在Django中扮演有趣的按鈕

我一直試圖更好地理解Django中的DeleteView，後面跟着this turorial，一切正常，除了我的按鈕標籤看起來不像它應該那樣。相反，我必須使用輸入標籤才能使其工作，這使得在提交按鈕中放置glyphicon-trash（引導程序）成爲不可能。在Django中扮演有趣的按鈕

我不知道它是否與我在pythonanywhere.com上運行它有關，因爲某些網站建議在某些條件下，按鈕標記將無法正常工作，作爲<input type="submit">的替代方法。

這是我的代碼。（我一直都在按鈕標籤和比較的目的輸入的標籤。）

<ul> 
{% for card in all_cards %} 
    <li>{{ card.front }} 
    <form action="{% url 'delete-card' card.id %}" method="post"> 
     {% csrf_token %} 
     <input type="hidden" name="card_id" value="{{ card.id }}" > 
     <input type="submit" class="btn btn-default" value="DELETE"> 
     <button type="submit" class="btn btn-default"><span class="glyphicon glyphicon-trash"></span></button> 
    </form> 
    </li> 
{% endfor %} 
</ul>

令我百思不解的最多的就是按鈕被點擊標籤時，它給了我此錯誤消息。

Failed to load resource: the server responded with a /like_treasure/ status of 404 (Not Found)

* like_treasure是在完全不同的Django項目中使用的目錄的名稱。

任何意見將不勝感激。

顯示我們url.py文件.. – Boky

@Boky：雙方提交按鈕張貼到相同的URL ... –

注意''元素有一個*值*，則''

剛剛從「url.py」到「urls.py」更改文件名。

對不起，這是一種類型。實際的文件被命名爲「urls.py」。 – Yuta
